Take over here and let's see if we can hear this, you guys can hear that bearing sounds dry. This video is brought to you by sport'ln quality, integrity and tradition. Today we have a somewhat of an emergency call on a kitchen AC, not working in that kitchen. Ac over there on the right - this is my unit right here and the thermostat is blank downstairs gon na open.

This up see we got in here. We have a unit that appears to have power, doesn't look like it has any safety limits on it. We've got a call for a fan and a call for occupied, but no call for cooling. So first, what we're gon na do is we're.

Gon na check incoming power. We should have 208 three-phase line, one to line two. My 1 2 line 3 mine to Deline three, so we have three-phase power coming into this unit. It is the correct voltage.

Then we need to check. Is transformer 24 volts, so I'm going to go ahead and check it at the terminal step towards thermostat, one 24 volts going down to the thermos whether or not we have 24 volts at the thermostat? Is the question: let's jump down there and take a look all right? We have a blank thermostat here and look right here. We've got some corrosion right there. That's not good and we're gon na go ahead and test for 24 volts at the thermostat.

Between R and C we have 24 volts presence, so it looks like we have a bad thermostat here. All right, I made a temporary repair and what I did was uh. We're in the middle of this kovat thing so they're only using their kitchen AC and their bar AC, so I grabbed the thermostat off at the dining room temporarily, just the faceplate swapped it over to get them through the night and I'll come back possibly tomorrow. If not Monday morning with a nuclear estat but they'll be fine.

For now I've got three-stage, cooling units running I double-check, the tightness of the belt and all the condenser fan motors are running so we're good for now and we'll come back out all right. We've got a new thermostat installed here and we just need to basically program it. We're gon na go ahead and jump up onto the roof and check the unit out. We got call for fan y1 and y2 and all the compressors are running.

So that's a good sign. That means the thermostat was wired up right. I didn't screw everything up when I was here the other day. I noticed that the indoor blower motor was making a god-awful sound, so we're gon na kind of investigate that a little bit take you over here and, let's see if we can hear this, you guys can hear that bearing sounds dry so shut this guy down and Pull that out and try to lube up the bearings or grease up the bearings and see if that helps, when you grease bearings, don't be that guy.

That leaves grease everywhere, got to get in there and remove the grease from the zerk fitting down in there, and it looks like these seals are starting to go bad, but yeah remove the grease that way. There's not a big old mound of it later same thing that can hear get the grease all cleaned off and I had gotten some right down here. That way, you don't get a surprise. These blower wheels are dirty man, things need to be pulled out and like thoroughly cleaned right.

We are going to grease the motor bearings now this one works out nice because we have a drain, so I can put a zerk fitting right here and then we have a drain out the other side that we were not just packing it full useless grease. So we're going to push the grease in there and then let it come out the other side then seal it up. I temporarily stole the zerk fitting from the bearing I just pulled it off, I'm going to put it on here temporarily and then increase these guys up on both sides and hope that that solves that problem yeah, those bearings were dry. I pushed it through and all that came through was mine.

I didn't even push out any old grease, so yeah those things were dry much better. The the motor pulley is going bad, so the belts kind of riding funny in there but bearings sounds good. I don't hear that grinding sound coming from there anymore, dad it's just that. Frickin Bell, pull o'clock comes up with new pulley on there, but all right cool.

My got him some more life out of that. They utilize that umbrella, like a lot to try to keep the Sun off my neck, because I'm so afraid of skin cancer, he's gon na start getting ready to put out my smartfrog. So I can check everything with measure quick kind of somewhat doing. Okay, the condenser doesn't legendary all right, so my unit recording to measure quick has a little low on the head pressure.

I'm sorry suction pressure, let's go ahead and scroll through some point is a little bit high. We don't really use self pulling on this unit. So much as we as approach, though, the approach temperature, the bay one, he's approximately six degrees. Our approach temperature right now is about four degrees, so it kind of acts like it might be a little overcharged, but it could also be a dirty condenser.

What's alarming is my return air? Do you see how it says? 85 degrees - that's really high, because it's not 85 degrees in that kitchen. Right now the airflow looks very low, too temperature splits kind of high. I already kind of have an idea. What's going on, I'm gon na take you over there and show you right now.

I had opened this a minute ago and I noticed something when I was putting my probe in there now look. This is a full-fledged economizer, we're pulling a hundred percent outside air, because the way it's set up the indoor air damper is completely closed. Now, it's probably for building balance because they have some funky stuff going on here with their balance. Let's look at these metal mesh filters plugged up these metal mesh filters are plug these metal mesh filters is your return air right now, because they're pulling so much outside here here right, so this is almost like a dedicated outside air unit, but it essentially has no Return air, so I'm gon na pull those things out and we're gon na watch that suction pressure and that airflow rise.

Alright, so that's a little bit better, but we still need to clean that blower assembly too. So this unit's definitely in need of some love, but its operational, I'm gon na go ahead and check out the other stages right now. Alright, this is my second stage now. Approach is low, dad we're going to jump onto the third stage pretty much the same on the second stage.

Third stage is running much higher head pressure. What the heck super meat is extremely high. Sub-Points extremely high approach is kind of on point, though that's weird alright, so at this point everything is is indicating kind of low air flow kind of seems like the unit needs a good PM. Obviously the metal mesh filters are plugged.

The condenser, I think, is kind of acting like it might be a little plugged up too, even though it doesn't quite look it. So we're going to talk to the customer, we got to get it operational by changing the thermostat, but we're going to talk to them about doing some p.m. work, because if you look over here, we got water leaking all over the floor. My umbrella is blowing all over the place.

Well, yeah you got water leaking from that unit. Just look at this just pouring out of here no butter just pouring out of that guy open this guy up, see what it looks like look at that I am. This thing is vibrating to all hell really bad. This is their bar unit holy crap.

That's not good. You got something stuck in that blower wheel, man, oh yeah. They need some p.m. work here, so we'll talk to them and see what they want to do.

I just pulled those metal mesh filters out for now. Okay, when it comes to calls like that, you know the customer doesn't always want me to do the big picture repair I went to them. We had a bad thermostat. I've said this a million times with all my videos right now we're in the middle of this virus thing, and they don't want to spend any money that they don't have to spend.

So the original service call was kind of an emergency service call where they wanted us to. It was late in the evening on a Friday, they wanted us to come out, get their air conditioner up and running, found a bad thermostat. I ended up doing a temporary repair. Okay, I ended up stealing the front thermostat, basically off their dining room, a/c, throwing it on to the kitchen to get him through the weekend and then I came back out Monday morning.

Changed the thermostat finished going through the rest of the unit. I heard a funny noise when I was there on Friday investigated it found that the bearings were dried out on the motor and on the indoor blower assembly. So I greased all the bearings. You saw high grease the bearings on the motor.

You got to be very careful when you're, when you're filling up motors with grease. If there's nowhere for that grease to go, it can become a problem sometimes on some of the motors. If you pull it, we start pulling apart motors when you change motors, pull them apart and just look at where the grease goes. Okay, oftentimes, there's nowhere for it.

In this situation I had a grease fitting and basically a drain, so I was able to push grease in one side, eliminate all the old grease. There really wasn't much left of it and put all the fittings back on. Then I put the zerk fittings back on the main blower bearings. Okay.

I used to carry zerk fittings in my van just like a little case of them, but I never used them so I took them out here. We go. I finally found a point where I could use them, but it is what it is. So I went to the customer and I let him know hey.

This is everything that's going on. I got you unit operational. We really need to do a good p.m. on it and they chose to just let it be.

For the time being, I even told him about the other unit that sounded like a helicopter about to take off on the roof. They said just leave. It be right. Now, until the unit takes a dump, they just want to leave them alone.

You know I still go into every call, looking at the big picture, giving them all the information and then that way when something bad happens after I leave it's, not my fault, I've, given them everything I've, you know given them my suggestions. This is what should be done. This is what's broken la-dee-da. I need to clean it before I can finish diagnosing that kind of stuff, but you know sometimes they don't go for the big picture repair.

It is what it is. I really really appreciate you guys taking the time to watch these videos, if you guys see any tools that I use in the videos that you guys like you can help to support the channel. If you choose to do so true tech tools, comm, you can use my offer code. Big picture.
