Man, the weather man, said there was going to be a cool down 115 on the route. It's warm. This video is brought to you by sportlin quality, integrity and tradition. I wanted to start off and give some context.

This video was filmed uh at the end of the summer of 2020, so somewhere around september of 2020, we were just going through a crazy fire season, so that should give some context to the time situation within the video got a complaint about a york package unit. Today customer says it's not cooling. I verified that the thermostat is calling visual inspection looks okay from in here. We need to go ahead and open up the control section in here and see if we have any safety limits, see what we got going on.

Okay, so yep, okay, let's count them one. Two, three one, two, three, four one, two three one, two three four and come on right down here: three is high pressure. Four is high pressure, so it's a high pressure lockout. Let's have a look at this condenser.

It doesn't look uh, it's it's kind of dirty kind of dirty. Let's go ahead and reset this bad boy and see if the condenser fan motors actually start up looks like a bunch of plastic bags. These units are really beat down all right, so i think i did this last time. I can't remember how you reset this: i'm holding down the test and reset button okay come on over here, condenser fan motor is spinning slow compared to the other one spinning at full speed.

So we got an issue there, all right, we're going to power it down and uh investigate a little bit further, oh, and that disconnect switch is also going bad. It doesn't really uh actuate very well, so we'll have to make sure that it fully engages when we push it back, got the run cap for that motor right here and uh we're gon na test to see if it's working, if it's got the right rainy, it's A seven and a half so that doesn't seem horrible, it's a little bit low, but okay, let's go ahead and test the other one too, and then we'll check voltage at the motor test, the other one, the other one's, also a seven and a half. Let's see what that one does that one tests kind of okay too, but you know i was looking at that labeling and that doesn't quite make sense, so i don't know which one's actually which but okay, i'm gon na put the caps back in. When you see these schematics and these uh legends use a brush and don't use your towel, because if you use your towel oftentimes, if it's a really old one you'll rub the writing right off, but a brush will typically clean it.

So, looking at the the legend right here, we've got a capacitor here, capacitor here so capacitor up top is number one capacitor below is number two and then let's go ahead and look and see m3m4. What are those we're going to have to go up here so see? This is a really good example. This one's really unlegible so just give it a good little wipe. You can see, that's already wiping off.

So if i get it with a towel, it'll wipe off real quick. So m4 is outdoor motor m4. That's this one right here! This one right here is condenser fan motors, so they both get powered at the same time. So we need to check voltage at that.

Contactor leaving it to see if we've got properly operating motors now i also want to inspect the motors a little bit to see if they're, both 1075's or 850 rpms. Their factory is supposed to be 850 rpms, but these all have aftermarket blades and stuff. So it looks like they've all been changed. All right got the side panel off got to those two stupid, hidden screws, um, i'm not seeing anything jumping out as far as broken wires and stuff go so we're just kind of giving it a visual inspection um.

I want to get in here. I need to rotate this motor to be able to see what the rpms are. I don't see them yet it's really weird. I thought this was spinning slower.

I turned it, so the compressor can't turn on um. This is an 825 rpm we're running under amps. We're allowed to run two amps 1.77, but i thought it was spinning slower. It looks like it's doing.

Okay, now, that's interesting. Okay, i'm gon na have to investigate the wiring a little bit more we're gon na power. It down uh while i got the saw it could be that we just had a dirty condenser. That's interesting though, but that one shuts down really fast.

That's me. I have that panel just pushed up there. Um, that's another thing, though too, with how fat yeah this one's got bad bearings. You can see how it's slowing down yep bad bearings, okay, um, i'm gon na go ahead and clean the condenser.

This is a beat up. Condenser owner knows it too we're doing everything we can to get some more life out of this thing. But it's just you can't even straighten these fans. They they bend so easily.

So i'm gon na go ahead and clean it and we're gon na get a new condenser fan motor for this guy right here, because this guy's locking up, i can tell um. Let me see - and this one i think, is a 1075. yeah. I can't even get down in there, but i'm pretty sure, that's a 1075.

all right. I actually have someone bringing me that other condenser fan motor, so i still have to make sure there's nothing wrong with this one, but for some reason i saw one spinning slower, but the reason why is because one's an 825 one's a 1075. and the 1075? I can clearly tell has bearings going bad on it, so i'm gon na go ahead and start rinsing this guy, i imagine it's probably pretty dirty because of all the fires and everything. So, let's see what we get out of this thing i mean the water is barely even coming through.

I think that's not even coming through at all, but this condenser is also very, very damaged, very, very damaged, but look at that. Oh, my goodness, there's just that stuff coming out of there really really bad just getting the surface stuff off and then we'll uh we'll start rinsing with cleaner and get from the inside out. But this thing they used to have a maintenance guy that used to come up here and um yeah, it's bad like almost not even gon na be okay. It there's like no water coming out of that.

Let's try the front the front's, pretty bad too. Barely anything coming out all right, we're gon na get the surface really good and then we'll uh put cleaner on there and try to get a little bit better yeah, that's pretty nasty coming out again. This is only gon na, be it's not gon na be perfect. Basically, but you always want to do a initial rinse anyways, because it helps the coil cleaner to run smoother down the surface, so go ahead and apply some of this coil cleaner in here.

Try not to get it on the electrical i'm using it. On the c setting as usual, oh no, but i'm not instantly, turned way too high. Now we're gon na go to the c setting there we go. That's better so we're just going to spray it all over the place i'll get in from the other side, too i'll get it from the front and then we're just going to let it sit work its magic - and this is the refrigeration technology's blue venom pack over There so let this stuff sit on there and i'll bring you back when we go to do the rinse off.

I'm letting the coil cleaner sit on that one and check this out this one's dirty too, because when i spray it look at the stuff just coming out the top. It's just blowing dust out. These fires are killing it right now and it's just black coming out. Um, if we come over here, they weren't even complaining about this one.

But this one has an error message too one two, three four and that's high pressure number two. So this one has got a problem too high pressure control tripped, so we're gon na go ahead and clean this one. When we're done with this one okey, let's see if we get anything out of this guy yeah, it's coming out slowly, yeah it's coming out dirty too cool yeah. It's definitely coming out nice and dirty, and that's just pure black.

Coming out, oh yeah, i like this wand for this reason, because you can get right deep down inside and watch all the crap come out nice and good, probably going to give it another coat of coil cleaner. It's not going to ever come through perfect because the fins are all bent, but one more coat of coil cleaner, just to make sure we get it as clean as possible. All right. I went ahead and rinsed from this side too.

All good put some rust buster penetrating oil on this guy, been sanding up the shaft, i'm gon na clean it and then try to get the fan blade off. I'm gon na have to reuse the guard because the motor that i have doesn't have a guard, but so i had this motor in the shop uh and it's a um uh oem york motor, but it had a busted fan guard. So i went and picked one up from the supply house, just the fan yard, where i had someone bring it to me. I also got a new capacitor for the motor and i got a new capacitor for that motor too we're gon na replace them both.

So we're going to get this guy wired in, but you always want to take note when you can of the motor specs and stuff before you button everything up. So that way, you can check to make sure it's working properly when you're all done redid the electrical uh, the wire wasn't long enough. So i ran some new wire up into here nice and good, secure into the connector. So we should be good they're going to get the fan blade on, i'm hoping that's an oem fan blade and it's going in the right direction, because this oem motor is not reversible.

You never know that with some of these people putting the wrong motors in here and stuff so we'll have to see all right new condenser fan motors installed. Let's see what happens, hopefully, nothing blows up an interfam motor spin in the right direction. It's moving a good amount of air. Both of them are 850 rpm.

Now i like it. Okay, let's check the current draw. Both of them should be running right around two amps, one of them, the new one's allowed to run 2.1 and the old one's allowed to run too. So, let's see i have the compressor still shut off, so we're running 1.85 1.73.

So both motors are fine they're, not over ramping. I'm going to finish putting this uh fan guard on, because i didn't tighten this up. Yet i'm going to tighten this thing up and then once that's done, we'll turn on the compressors and make sure it's all working right man, the weatherman said there was going to be a cool down. It's 115 on the route.

It's warm all right, so this guy's turned back on i'm waiting for the time delay to go through, and everything and uh i'm gon na go ahead and pull the side off of this guy and go ahead and do a thorough cleaning on this. I did do some research and find out that their preventative maintenance is actually due this month, so i'm gon na go ahead and get a jump start on it and get some of this stuff done that way. We can spend time doing other things even rinsing. This guy from the front, it's still coming out pretty dirty, so i'm gon na give it a good rinse and then we'll get some good cleaner on there same thing on this side, yeah it's coming out and then i'll try to clean up those wires.

So this guy's pretty dirty in here too, but it's coming through. It's just coming out nice and slow all that brown stuff working my way up, so these things just needed a good cleaning, all the fires and the smoke and the ash is just killing everything all right. We are going to profile this system and measure quick right now, so let's go ahead and open it up and we'll set everything up uh. This is a 90 000 btu seven and a half ton package unit r22 refrigerant with the txv.

It is a heat pump, but we're not worried about the heating right now. So first we're going to change the refrigerant to r22. Then we're going to go to system info we're going to set it up as a package unit. 90.

000. Btu. 7.5 ton. It is not 13 to 16 here we're going to say 10 to 12 seer.

Everything else is okay. We hit submit and we're all profiled. So now i just need to go ahead and hook up all the probes, so the first stage uh the unit, ended up. Having a piston, so i changed it over to piston um first stage we're running high head pressure, which, with the shape of that condenser, i totally expect that let's go ahead and scroll on over super heat's, looking really good.

Everything else is doing good 106 degrees outside sure feels like it's hotter yeah we're looking pretty darn good notice, there's no latent load. It is extremely dry outside right. Now, all right we're going to go ahead and jump on over to the second stage, see how that's performing okay. The second stage is looking better.

As far as the head pressure goes. Um, the superheat again is looking good. Everything else is cool, i'm not worried about it, so we're gon na go ahead and let this one go. I've already talked to the customer about that condenser they're.

Just trying to make this thing last all right. I ended up mixing up the compressors. This is actually the second stage and the other one's the first stage, but i have the probes in the right spot. So the first stage, conde or second stage condenser, is the one that's just flattened to all heck, there's nothing.

You can do about that. That condenser is trash so um. It is what it is like. I said the customer knows, but that's it um.

The filters are dirty too, but uh they're. Preventative maintenance is due. So we're gon na come back next week and change off the filters and change the belts, but i took care of hosing and cleaning all the condensers, so all is well we're. Gon na wrap this one up all right.

This one was a service call on a heat pump unit, obviously not working in the cooling side. Okay, it was extremely hot outside we were going through a crazy summer. As i said, this was the end of the summer of 2020 and the customer just called saying the ac wasn't working now, as you guys saw in the video. They didn't even know that their other unit wasn't working either.

So this is that hole, don't walk in with blinders on. They called me about no cooling on half of their building and the other half wasn't working all the way either. One of the stages was out on lockout two because of a high pressure situation. Okay, so of course i communicated with the customer made sure they were okay with it and then went ahead and cleaned that unit up too okay.

So the main one, though, that the problem we had a failing, condenser fan motor, so you can't just go up and say: hey both the fan motors are working and walk away. You got to investigate more use your senses. I noticed that one of the motors looked like it was spinning slower than the other one right so immediately. I thought the one that was spinning slower was problematic.

No, in fact that was the one that was working properly. Someone had taken an aftermarket, condenser fan motor that had the wrong rpm on it and put it on that unit. Okay, so the one that was actually spinning faster. It started back up, but the bearings were failing so eventually it would have slowed down and locked up and made the unit go off on a high pressure situation.

So using my senses i was able to look and see hey. One of these motors is spinning faster than the other. Something was wrong, you know and then turning it off spinning the motors and you know again just getting used to how things work. I'm able to look and say hey that motor shouldn't be slowing down that fast.

When you spin it by hand, it should be a nice gradual slowdown instead of an abrupt stop like it was doing so. It helped me to diagnose that we had failed bearings on the motor. Now it worked out perfect because, as usual, i'm not a fan of putting the wrong motors on these units. Okay, so let me preface that a little bit, i'm okay with an aftermarket motor right, but here's my dilemma with aftermarket parts.

When you use aftermarket parts, you have to use brain power to make sure that the part is suitable for that unit. A condenser fan motor. We have to make sure that you know the size of the motor is correct. The shaft size is correct.

The rpm is correct. The current draw is correct, all that stuff, and it's not that i don't like using aftermarket it's just that. I don't like to have to think that hard. It's so easy for me to just say: hey, let's go get an oem motor because boom, it's done no thought power involved so long as you put the right motor in it's easy, okay, so the motor that was already in the unit that i left in there In fact was an aftermarket motor, but it was an 825 rpm.

It was running properly. The wiring needed a little bit of help. I fixed that and it was okay. So i left the first one: okay, that was an aftermarket motor there.

It was working fine, the one that i replaced was actually a factory motor and i went ahead er. No, the one that i replaced was an aftermarket motor too, but um. I went ahead and put the factory oem motor because i had one sitting in my shop. It was actually worked out perfect that motor actually had been sitting in the bottom of my shop, and i was trying to figure it out because i thought maybe it was for like a linux unit.

But then, when i looked at it i was like that's not a linux motor, you know and then it just so happened. Like a week later i was at the service con. I was like. I recognize that motor.

You know. I know where that other motor is. That's in the back of the shop, so it was kind of cool because it had just been sitting in the you know the corner of the shop and i was able to finally utilize it. That's why i'm not a huge fan of throwing away like old parts that are sitting in the shop as long as they're, still good i'll, just tuck them back there, because you know, if they're not taking up important shelf space, then we'll make use of them eventually.

In the future, so this one was a bonus right so got the system, operational change, the condenser fan motors and clean the condensers. Okay, now um, i use the the the coil brightener or viper bright venom pack, the blue venom pack on this guy and that stuff really does a great job. But you need to be very careful to make sure that you use the concentration correctly. Okay, if you mix it in correctly, it can have some adverse effects on the condenser, so we got it cleaned up as best as possible.

Now that condenser is trashed. Okay, it's not going to be perfect, so i did the best i could and that was reflected in the refrigerant pressures, guys those refrigerant pressures. You know the high side was a little bit high, but that condenser is just trash, there's not a whole lot. We can do on that, okay, so it's now been several several months.

Customer was happy. You know we have warm cold weather all that good stuff. Since then, everything's been good. We did end up going back a couple days later and finishing up the preventative maintenance and the cool thing was since i was there on a service call.

I did a lot of the work that we would have done on the preventative maintenance. So when i sent my guy back out there, he was able to focus on other things, such as the ice machines and the walk-ins and stuff like that, more so than the normal time we have allotted on it. So it worked out perfect all right um. I really really appreciate you guys making it to the end as usual.
