All right before I start this video off, I just kind of wanted to say a few things. I am looking for a new service technician to work with our team to add to my team, okay, but here's the caveat, I'm looking for a service technician with experience that lives in the Inland Empire. Okay, I our offices out of Riverside. We mainly work in the Inland Empire and Orange County okay, but I need someone right now in the Inland Empire to add to our team.

We're, obviously you know, got lots of work going on and I've just been thinking about it for a long time. I wanted to do this before the whole virus thing, but I needed to kind of get through it as we're coming out of it. I'm ready to do this. Okay.

Now I am looking for an experienced service technician that is capable and already works, or knows how to work in the restaurant side of things. Okay, I do restaurant refrigeration and air conditioning. I work on air conditioning refrigerators, ice machines, walking coolers, prep tables. Okay.

I do not do any hot side work. I don't work on fryers. I don't work on soup wells, any of that kind of stuff. Okay, just the refrigeration and air conditioning side, like I said, an experienced technician right now now, as far as the people that aren't experienced and cannot hit the ground running at this point, I will be willing to train soon, but not yet okay, so the resumes that I'm looking for right now is for the experienced service technician that has experience in the restaurant side of things.

Okay, if you have that experience and you're interested in working with me, you guys have seen from my videos - I'm probably an okay, but I mean we. We treat everybody right. I just expect things to get done right all right. I really really care passionately about the customer, the customer taking care of them, making sure that we're fair and honest with them.

Okay, we're not a sales driven company; we're not there to push crap down people's throats, that they don't need, we're there to fix their equipment to do it right to get it working to be honest and to make good money. That's what we're here for okay! So if you are that service technician and you live in the Inland Empire of Southern California and you're interested in coming to work for me, I'd like you to send me a resume to HVAC our videos at gmail.com. Again, I realized that there's a lot of people that are going to want to apply that don't have the experience guys, I'm not looking for you right now, but I will be soon okay, but right now, I'm just looking for that experienced service technician that lives in The Inland Empire that wants to come work with us I'd love for you to join our team, so send me an email to HVAC our videos at gmail.com yeah. I'm gon na change that right now and you know what else I'm gon na do - is we're gon na fix these empower this guy down and fix this? This video is brought to you by sport'ln quality, integrity and tradition.

Today we have a call on a kitchen AC that is not working properly. This is not one of my normal locations. I've done some work to help them out in the past before here, anyways long story, but so we're gon na dive into this guy. They did send me a video of what was going on and whether or not it all makes sense, but they had a transformer that was tripping like a secondary circuit breaker.

So we open it up and we've got a number ten on the m17 board looks like we have a full call for cooling G, y1, y2 and occupied signal. Now the customer told me they came up here, thinking they could fix it. You see the trip transformer, but they had told me they thought maybe the fuses they were just kind of reaching, so they had pulled the fuses out. So I have the fuses.

I'm gon na go and put those back in and it looks like. I believe this is the secondary transformer is tripped so we're gon na dive into it. Alright, I threw the fuses back in and powers off to the unit. I've confirmed it, I'm just doing a visual inspection, and this unit is a mess.

I mean little things like look, someone there's a relay missing: it's a combustion air, so I'm assuming this thing has no heat. All the wires are just they're. Just it just seems like a mess, and it's weird though too cuz look up here. Look! Look at this seam right here.

You see that seam, it's like and there's a bunch of screws, and I don't know it looks weird looks like someone was wrenching on it. It's guy like they grabbed it with channel locks like what the heck are they doing. So this is the return air section and like look at that, the insulation is just falling down these cheesy filters in there ridiculous, but look at look at how much stuff we see. We just see wire shorted.

This thing is greasy of salt, get up it's nasty, but like a mound of grease that came out of that hole, so obviously they have a greasy kitchen. Filters are dirty. Look in here same thing like look at the the top of the unit someone's been. I don't know why they would have pulled the top off of one of these there's really no reason to unless someone didn't know what they were doing, but things a mess.

I mean drain pans plugged up full of water. That's a large amount of water in that drain. Pan. Oh, it's gon na be interesting.

Look at how many extra belts there is like. I said this is on my store, but we're just looking for any obvious signs of a short or potential short causing the transformer to trip things just sitting there rubbing on the bottom things. A mess belts are somewhat snug, but like look at the top of this unit, I mean people have done some silly things in here. You know that I mean you know it's a mess.

I don't know what is going on here why someone would pull the top off this unit, these Lennox units there's really no reason to pull the top off. Look at that! That's crazy! All right! Well, I'm looking right here because this is where the hinge from the door goes right here, I'm looking to see if we have a short right there, maybe no doesn't look like it, but that's interesting I mean could have some. No, I don't see any cut wires, but man this unit is just beat down for real whoever's. Taking care of this place is not doing a good job and down in here I'm just looking for any wires, see all sorts of things.

I think there might be a refrigerant leak too, because there's oil all over that 3/8 copper line coming down in here all right. Well, you got ta figure out. What's tripping that transformer, so we're gon na start, troubleshooting looks like an economizer jack, whether or not that's actually even hooked up. I don't know so.

I started off by removing the ground wire from the transformer because they ground them out oftentimes on the common side. Now there could be other ground sources on the common side of the low voltage transformer we're going to start there. Now. I also verified that I have a good ground to the panel in multiple places.

I verified. We've got a good ground, so then we're just going to go from there's a terminal strip up here. It goes pink and then gray on the bottom gray is the the common side of the transformer low voltage. So we should have no short to ground on the pink.

That's the high voltage side and we've got a direct short to ground right now on this low voltage transformer. So we need to trace out that problem. We have a direct short to ground on the positive power side of the low voltage transformer and it's going to be starting on any one of these five wires and we can trace it out from there to figure out where the short to ground is all right. I have confirmed that this transformer is labeled T 18 and this transformer is labeled t1.

Our problem lies more than likely in T 18. If we come over to the schematic, we can see right here. This is the electrical symbol for a transformer. So this is one transformer notice that it says t1 and we come over here.

Here's another transformer and it says T 18. So they have one ladder diagram right here, showing all the different low voltage things that are going on in here. So what we need to do is we need to follow T 18. So if we follow it down, it's going to this ladder right here and each one of these dots is a connection point so relay K.

159. That is a symbol for a relay, so k. 159 is what we need to look at. I've marked them all que 149.

We need to look at que 150. P. 118. You notice right here, there's no black dot.

That means that it's not making a connection, that's kind of like a jump over. So this is controlled by the other transformer. So we ignore ignore, ignore look right here. We have the black dot so k1, 14 and then k3.

So we need to investigate those relays and the the wiring going to them to see if we can find where our potential short could be all right. So what I'm doing is this is a mess by the way there's wires going everywhere, but um. I started at K 159 because that's the first relay that I came across and I checked across the coil to make sure that we had good resistance and we did the next one is K 149, which is the outdoor fan relay. So I'm just testing the relays.

First and what I'm gon na do is go ahead and test to make sure that my relay across the coil has resistance, forty-four ohms, and that was about what K 159 had also it's kind of difficult to see. But if you look on these wiring there's labels to make sure that they're going to the right place, so you can actually verify this one's a little faint. But this one says K 149 a and if you look on this relay it says a so. This one goes here: k 149 B is going to be the common all right and I'm gon na go ahead and disconnect the comments to each relay because we still do have, I think, a grounded wire on the comments, so we're gon na disconnect the comment and Leave them unhooked, if I can do it carefully so that way, we can still trace this problem out.

All right, I couldn't find the source. I still have some things unhooked, so I powered the unit back up and we're gon na see what happens when we get a call. We've got no call powers applied and we did not trip the transformer yet so we're just gon na monitor and see what happens? You know when we get a call that kind of stuff, so alright a couple things talking with the manager again, this isn't my location, so I'm trying to make sense of some weird stuff. First off, I don't like wires just hanging down like this.

You know, but this transformer it just doesn't look right, so I start investigating a little bit more and I find out that it's only a 50 VA from the factory. They have a 70 VA in here. So I'm gon na start there, okay, whether or not there's a lot of wiggle room in the factory's transformer - I don't know, but we're gon na start by putting back the proper transformer in there. The next thing I'm noticing is that when I apply voltage to this contact or powers not apply to the unit right now, but when I apply voltage, I've got 24 volts and this contactor is not pulling in, but it's owing out good.

So I don't know what's going on here. This is a little interesting, so we're going to start by putting the factory transformer or the equivalent. I'm gon na put a 75 VA in there and then we're gon na clean up this mess in here and then go from there. Alright, I got the new transformer in there.

The wires are tucked up. You know nice and neat plugged in where they should be. I'm gon na clean up some of this too, but next thing I'm doing is I happen to have one of these relays, so I'm gon na go ahead and wire this up. So we don't have a bunch of wires just dangling in here and if you look in the bottom of the unit, especially after other people played with it, you'll start finding all the screws, like here's all the screws, the extra screw for that guy people just drop Stuff for the most part, so you just look down, see there's another one too people just drop everything so we're just putting the unit back to factory specs and then we'll continue our troubleshooting okay.

So we have a call for G, my compressor cut. There goes my compressor contactor, just called them hold it. Okay, you know we have a compressor contactor we're gon na watch this guy, because I don't like doing what I did and that I just started changing things without finding exactly what was wrong. But the problem is: is that I'm undoing another company's mess, and so it's like? Where do you start? Sometimes you just got to pick a point and start so I started by putting the relay back in and getting rid of all the dangling wires.

I started by putting the proper transformer in and then we're going to continue to troubleshoot, so we're going to keep watching it. Watch all the stages come on and see what happens. I have got all stages, calling right now k2, which is not on that transformer is chattering or buzzing, it doesn't have voltage drop across it, but that one doesn't affect that transformer, but we're probably going to change that contactor, though I'll make sure that we got a Good 24 volts coming in so far, I'm not seeing anything that would cause the transformer to trip, but I will say that the condenser fan motors aren't cycling correct and I think that they've messed up the wiring. So I got to go through here and figure out.

What's going where yeah see this one's labeled 4k 150, which is condenser family for so they're, not staging the condenser fan motors correctly, and that could cause a problem see when you walk up to things like this. It can be a cluster F, trying to figure out what other people have done. So you sometimes you really got ta, look at the big picture kind of a thing and try to evaluate and undo their mess before you start troubleshooting. So what I noticed was when just one compressor was running my condenser fan motors for the first stage weren't running - and you know I have them labeled here according to the skin.

It didn't make sense. So the first stage is the top half of the front of the condenser. So, theoretically, we should have been running these to one of them cycling on pressure, one of them running so I got to go through but, like I said this one's labeled, K, 150 and it's on you a 68. A 150 is number four, so I got to figure out which ones are which and label them.

Alright, I swapped them. So these two bottom relays the condenser fan motors for flip-flops, which could cause my head pressure issues later on down the line. So I verified all the condenser fan motors are wired correctly and controlled by the respective relays. That does not sound yeah.

I'm gon na change that right now and you know what else I'm gon na do - is we're gon na fix. These covers to welcome power. This guy down and fix this, so I replace this contact her because it was buzzing chattering making not. You know not working correctly and I had the right voltage and then I reversed the covers unn trigger myself.

One thing I will say man, this uh indoor blower assembly is really loud where that belt could use a tightening. I'm talking to this customer they're gon na have to let me come in and do some PM work, because this is disgusting. These drains, I'm on overtime. Today, because it's a Saturday, so this has literally just get them out of a bind and then we'll come back and clean it up we're back up and running again all stages you can see.

I can actually hear myself think and it's not buzzin my face off anymore. You can only do so much when it comes to zip tying things in here, because you don't want to put too much strain and stuff the only thing I did it doesn't look the greatest, but I got these from laying on the top of this box. Just zip tied up and then just kind of zip tight, it's kind of weird. If you look at the control voltage, they brought it in through.

So I'm not gon na redo that right now that's kind of a loop. That's silly really don't want to be running that control voltage with the high voltage either they look at another time. Just kind of went through here is, if tight a few things up, mainly in here couple zip ties, got it nice and tightened up yeah just still watching the unit operate seems to be good. So far came over here to this economize, er actuator and I actually tested it the actuators not working.

We had a signal from the unit telling it to open. It was maxed out and this the actuators not moving. So I went ahead and unplugged it for now. Just to eliminate it as a overload or anything and we're gon na go in here we're gon na secure this sensor, while I'm assuming that's the enthalpy sensor, probably - and I don't think it's running so we're just going through and just you know, fine-tuning a few things Making sure we're not you know, don't have any other shorts and again, I'm gon na talk to customer to letting me come back and clean this unit up, hopefully, according to measure quick, our head pressures a little bit low, our suction pressures, a little bit high.

Let's go through the numbers here and see what we got super heats on. The money. Sub cooling is just a little bit on the high side, but I'm gon na be honest with you. I'm not too worried about that sub cooling, liquid line yeah seems to be coming and going.

The approach is really low. This is a Lenox unit and we don't have a very good TD right now. We only have a 14 degree temperature split on this guy. Okay, so the first stage doesn't look horrible to me, we'll pull up measure quick and see what it has to say.

I'm just gon na go ahead and clear that out low load on the evaporator. I agree because it's really cool in the kitchen potential duct leakage. Maybe system maybe overcharge, that's you know that approach being really low. It's possibility, okay, so we're going to go ahead and gage up on the second stage and see what that one looks like an important thing to remember on these Linux units when you're, usually measure quick, is it's important to draw out which condensers, which you will get A different air temperature in here, as opposed to out here because, let's say the Sun is beating down on the condenser, so you can you've got to make sure that you get your air probes put appropriately in the right place.

So this one, because I'm deal with the second stage now well, the other thing too is you want to make sure all the condenser fan motors are running. So the first stage was on this side. Second stage we're going to go ahead and grab in here, because the second stage is the top half of that guy and then the third state is going to be a mix of the bottom. So alright! So, let's first off I'm on the second stage, we have high suction pressure high head pressure, our approach temperature is lower than what the factory wants it to be.

I mean we're close. The factory wants about 8 degrees approach on the second stage. Let's go ahead and scroll back here, subcooling about 14 degrees, I'm not too worried about that. Linux doesn't publish subcooling, but I tend to see in the 1415 degree range, so it's not horrible.

I'm leaning towards on all of these guys that this unit needs just a darn good p.m. I'm leaning towards dirty condenser possible overcharge, but I don't think so. We'll see we're gon na gauge up on the third stage. Now: okay, we're on the third stage, we're a little low on our approach temperature, it's kind of ranging back and forth, but the factory ones, 9 degrees approach on the third stage.

Subcooling is a little bit higher oops when we have a fancy cover on our tablet. It's showing my head pressure being a little high suction pressure being high, but overall everything is running. We still don't have a great temperature split across the unit, we're still low on that our BTU output is low, but we need to clean this unit up as unit needs. A thorough, condenser, coil cleaning.

Also what's kind of weird is these - should all be the condenser? The same condenser fan motors and they're all amping differently, one of them's amping. I can't remember if it's a lot and I are a lot lower, so we could have it's possible. I need to investigate it. When we come back, they may have not put the right to nets or fan motor in there and I'll show you those numbers real quick.

So the condenser fan motors are actually rated at 2.4 amps. So, actually that's how bad two amps, but there's one of them in here - that's really weird. 1.79. That's really low! That's condenser fan motor number one two amps, the other ones running two amps I've tested it.

So we got one running 1.76, which is kind of weird. It is really weird because the one running the low amps is actually this one, a unit just satisfied to shut down, but they're all the same motors. It's ready to run 2.4 and this one's running 1.76, but all the other ones are running 2 amps. It's kind of bizarre huh.

Well we'll talk to him again. We're gon na have to come back, so I am back the problem persisted so I left on a Saturday. It ran all day, Saturday no problems and then took a dump again on a Sunday. This is the problem that the manager had told me about.

Originally that I didn't see when I was here is the transformer keeps tripping, so I reset it right now and it trips again further investigations kind of telling me a few things. So again, this isn't my location I mentioned, and another company has been servicing this and I'm remember. I showed you guys in the video that, like hey, that someone had taken the top off the unit, I don't know why stuff was just you know, wires were undone, it looked like someone had been troubleshooting this now I had asked the manager hey. Do you have an invoice from the previous company and they said no, they can't find it.

I told him that would really help me, but I'm looking at a few things right and notice that people have written codes, 10, 49, 47 and notice that we come over here and someone has marked 10:14 and then, if you come in here, that's actually my error Code is 10 because it's just a low voltage short and what happens is when I reset it. Well, it's not gon na. Do oh yeah, it's gon na. Do it right now, but it just trips again, so we're gon na have to get in here.

Oh, no, I have to reset the board to get it to trip again. So if you hold this down power it down and then watch it'll trip right away when it starts so I got ta trace this down. This obviously has a problem that I think the previous company was trying to diagnose the same issue and all that I know the manager had told me was they changed a thermostat? That's all that I know they have done and now remember when I came out here. I found they had the wrong transformer.

I found that there was a relay missing. I cleaned that up and I couldn't get it to duplicate the problem. Again. 24 volt short scale 20 different variables in here I mean it could be in the circuit board.

It could be in a lot of things, so I'm gon na get to troubleshooting and see if I can show you guys what I figure out. I disconnected all the thermostat wires and what I'm gon na do I reset the transformer it doesn't trip by itself, which tells me it has something to do with the call for cooling, who knows so we're gon na put the unit into test mode and see if, If we can run it in test mode, so we're gon na go shift unit test. We're gon na go see 11 for full cooling, see 11 full cooling. We're gon na see what happens there.

Goes it trips, okay! So that tells me it has nothing to do with the thermostat okay, so we're using some troubleshooting techniques. It has absolutely nothing to do with the thermostat, so we can trace it from there now it has something to do with the unit wiring. Let's do another test here and what we're gon na do is go ahead and take it out of test. We're gon na go shift unit test and we're gon na reset it okay, and then we going to test each individual component because you can do it that way too.

So we're gon na test each individual component and see if we can figure out where the problem is by testing each component. Understanding everything about this unit can be a little difficult. I've traced, my my trying to trace my problem to the the indoor blower contact, or at least that's where I kind of associated with and what I did was I come over here and I start noticing some markings terminal board. 24.

I found terminal board 24. That's right here and it's literally just a junction point: the wire comes out of the board goes into that comes back up goes into the board, but I start looking at the connectors that are also connected to this, and then I start thinking what else is going On with the indoor blower motor - and I start thinking about some limit switches for the heating section, okay and then I remembered that hey, I had seen a problem with limit switches. So I come over here and I saw this the other day and I don't know why junk didn't jump on this earlier. This limit switch looks like junk and I went ahead and disconnected all the wires from it and it no longer trips.

So this is one of those ones that was really difficult to find. Cuz low voltage shorts are always difficult on these units, so I disconnected it and let's, let's see if we can duplicate our problem, so we can put it into test mode. Now I'm just testing the blower decimal pops up, indoor blower turns on and we're not tripping the transformer. So I'm gon na go ahead and hook that that limit switch back up and see what happens and let's see if it trips again, so we're getting good nope.

It's see it's an intermittent short and it's somewhere in that limit, switch it's intermittent huh. So let's take a screwdriver see if we can get it to trip by tapping on it. That's why I couldn't find the short the other day. Now, I'm not going to do it, but it's intermittent comes and goes so we're gon na disconnect that limit switch and then get them some new ones.

What a pain man! Alright! I went ahead and disconnected this one for now and I climb back here to disconnect this one and I'm gon na. Take you back there and see what I see it's one of these things that just drives you, nuts look at the wire right here. Intermittently shorting drive you nuts man, all right, I'm just gon na disconnect everything these wires are numbered, so I'll know how to rewire them we're gon na get to new limit switches. I'm hoping that this is that again.

This is an intermittent problem, so put a pain in you're right. We started back up and it recognized that we have a primary heat limit, which is the one that we bypassed. I'm going to turn off all the gas valves, so the heater won't turn on and will actually turn off the main gas too, and then that way we can order the limit switches, but I'm going to test the unit to make sure that everything works right now. One of the things that you got to remember in the beginning of this video - I don't know if I caught it on camera or not, but I said something about those limit switches.

I said they looked like crap. I remember and you've got to trust your gut. So it was an intermittent problem right because I was like where's. This short, I started to try to chest the ground and I really wasn't picking it up.

It was weird I was getting and it makes sense it's intermittent now. Okay, because I got a short, but then I didn't get a short. It was just tripping me out and that's where I started, by putting the unit back together, putting the correct transformer in there replacing that relay where the wires and then I just inspected everything and I couldn't get it to trip again. Okay, I didn't think twice about the writing from the previous company.

I didn't even look at that. You know and same thing here. I didn't even look at that and then but then, once I started to investigate, I see that the previous technician was using the same logic that I had and they were, like. You know jumping through that stuff and I should have addressed those limit switches when I saw it the first time, because I might not be here today - it's not my fault.

This is still billable time because, especially because I'm coming in on another company, I have to fix what they did before. I could you know, because it you know it just happens that way. Okay, now it'd be one thing. If I was the technician to disconnect all that stuff and then leave it that way, yeah, I probably would you know, kick back on some labor or something like that because yeah whatever, but no, I'm not kicking back on any labor on this one.

That's the way. I'm rolling because I had to put this unit back into operation from the factory essentially before I could go any further and I explained that to the manager. In fact it was written on my invoice to so. This is all billable time, but I am gon na order.

Those relays and that'll give me some time to make sure that we don't have any more intermittent short issues. There certainly is a lot wrong with this unit plugged up filters, economize economize are messed up. You know there's this units beat down, but I'm pretty sure that we got at this time, because I was a little unsure when I had left on Saturday. You know just changing the transformer in the relay and I couldn't couldn't duplicate the problem and that's why I covered my butt and explained to the customer that I had to start over and you know because usually when I do something like that, I want to see The problem, because I don't want to make a guess or assume, because sometimes this happens and it makes you second-guess yourself - okay, so that's what we're at we're gon na order that limit switch and then I'm gon na go down and turn y1 and y2 on it.

The thermostat to make sure that we get a full call and no trips. Alright, we have a full call for cooling. We are staggering between 60 and 50 as an error code, and that's primary limit switch one primary limit switch, to which I have them bypass and that's another thing to I was thinking. Why would a limit switch when it's in the cooling mode trip to safety or trip the transformer? Well, with exactly the point being that it shows the error message, it's always providing power to that like right now, we're not in heating mode, but the board is recognizing that I disconnected those limit switches.

So it's always applying power to those limit switches. It was intermittently making, it was intermittently tripping it basically and again, it makes more sense to because if I go to this terminal board right here, it says w2 on that terminal board and the limit switch that actually with a further one, was the one where the Wire was disconnected and that's w2, so it has something to do with this section. It's probably powered by this transformer. You know that whole thing.

So again, I'm thinking in my head like. Why would it trip you know the cooling cycle and all that stuff? But that's more than likely, it makes sense to me that's why so yeah we're gon na order, those limit switches and then go from there came back out today to replace these bad limit switches that we're all shorted got them both installed that one right there and Then the other one back in there, the wires are secured now so they're not rubbing on anything. You know nice and high, so yeah we're gon na start it up. Alright, I'm starting the unit back up, no error codes displayed.

What I am gon na do, though, is reset the error codes. So we're going to go to recall and see it's gon na show you all the different error codes we're gon na reset them all, so we're just gon na hold down the button until it disappears. Zero so now there's no error codes in the unit and we're good. Now I need to see a full call for cooling without tripping the transformer and we'll be done with this one, all right, so that one was you know, another interesting service call right.

This situation was, I was called to help out a location of a particular customer that I don't normally service. I've been doing that a lot lately when we're kind of we're kind of slow coming through this virus thing, and so I've been able to help people that are usually out of my source area, mainly just because the the location is so far from my service area And the traffic is ridiculous is why we don't service that location anyways. They were having a lot of issues with an air conditioning problem. They wanted me to come out and kind of go through it for him, so went out there and what I found was.

It was a mess as usual right and I had to put it back into normal factory condition before I could really troubleshoot what was going on, because you know I tried to troubleshoot it with the way that it was, and it was just. I couldn't figure out where the short was. I was picking up when I initially got there. I was picking up a short combing it out, but then it went away and I couldn't find it and I kept going and I and it just disappeared the short and it was tripping me out so then I decided okay, I'm gon na put this unit back To factory spec put the right transformer in it fix the couple spots where there might be a short put that combustion relay back in and it didn't do it anymore and the unit started up and ran.

I saw all stages of cooling going. It ran for, I think, a day and a half, and then they called me back after that and they said hey. I went down again, it's like okay. I was already anticipating going back with with something.

What was it? I wanted to go back and clean it. That's right, but um anyways. I ended up going back and found the problem. The problem was the limit switches for the the gas heating section.

Okay - and I showed you in the video that it was that one wire that was just every once in a while shorting out - I didn't see it from the front of the unit. I still don't know why the other company had taken the top off that unit, because there was no refrigeration repairs made to that unit. I don't understand, I don't know it's sometimes you're, never gon na make sense of what other people are doing to those units. It was you know, it's still that unit looks like crap, but I ended up finding the short it was in the combustor and that little limits, which I ended up, ordering new limit switches coming back out, putting them in and the unit is operating.

I mentioned this. Probably in one of my recent videos before this that I made a lot of recommendations to the customer to have me come in there and p.m. that equipment and they declined that right now, I'm not angry. I mean it's a little bit frustrating because you know I want.

I don't want that to turn into another emergency service call, but I kind of understand because we're going through this virus right now, the restaurants still are not open to Dinan seating, so they're not making any money and they're basically in survival mode. So you know they just need to get things patched up and operating so that way they somewhat work. I guarantee that they're gon na have me go back in and clean those once they open up the dining rooms and in fact the dining rooms are gon na. Be opening here in the next couple weeks to limited capacity but they're gon na start rolling stuff in and we're gon na start getting a lot more service calls at these restaurants, and in fact, most of my restaurants, that I go to all have particular pieces of Equipment that are broken and they've just been kind of holding off, because they're just trying to save money there again, like everybody else, they're in survival mode.

Okay, so they declined the preventative maintenance repairs. They don't want me to clean anything because it's operational so long as it doesn't become a problem and, like I said, they'll call me back and we'll go back later. Okay, but you know the whole big picture. Diagnosis thing that I'm always preaching guys all right.

You you know you got a look at everything: okay, even myself. I find myself thinking. I said it in the video. I should have listened to my gut when I first opened up that into a blower section, and I saw on the front limit switch that the ground wire.

There was a ground wire. I don't know if you guys can catch it on film, but there was a ground wire that was dead, broken off from the limit switch and someone had grounded it out. There's nothing wrong with that. Okay, it just the the wire itself grounded out.

I mean a you know had broken off and I should have dug into that more, but I just saw it and then kept on troubleshooting. You know and then when when I changed the transformer and the combustion relay or replaced them and the problem didn't happen again. I was like okay, you know I'll follow up. Another thing was, was that was a Saturday morning call you know, and it was like.

I really didn't want to be there all day. I was already there for a couple hours trying to find a short, and I was a little bit frustrated. You know, of course, I'm kind of going against my better judgment, because my better judgment is is to always give them all of my attention and spend all the time in the world, but it does get kind of frustrating when you get called out on an overtime Call and the unit's filthy the drains are plugged up all this stuff and you're, like you know what they're not gon na get all of my attention right now. You know so I battle with that too.

I know I stress to you know, take care of the customer with the utmost professionalism and stuff, but there's times that you get frustrated too okay, so I can only give them so much, and you know some of my personal time on the weekend, even though I'm On call, you know they're only gon na get so much and we'll come back when we're not on overtime and follow up and clean it up. That's sometimes my logic. Okay, to an extent, I guess I should say, but but anyways we found the problem. It was an electrical short, it was.

The limit switch is replaced them it's since been a week. Customers still happy, no complaints, that's pretty much! It really appreciate you guys taking the time to watch these videos and we will catch you guys on the next one. Okay.
