 This video is brought to you in part by TrueTechTools. Quality tools, essential support. Well, it's Monday guys. Let's get started again. Let's go see what's going on here. We have a say kitchen AC unit that keeps tripping the breaker and they keep resetting it. I've went in here and taken some basic looks around and got some basic information what we got right here. AD amp breaker that keeps tripping and we need to go up here on the roof and see what's causing it. All right, this is K1 and of course it's raining wonderful weather and we're pumping heat so it's not an immediate refrigeration issue at least with the circuit that's running. Now we could have fan motors failing because that's all kinds of stuff. Everything's R22, both compressors are running. What do we got tripping here? We have a blower fan motor. What's failing? I'm shorting. We got to start digging in to find out. Yeah, let's go ahead and get started with our total amp draw here. We're pulling 50 amps of the compressor because we are below the 20% threshold of 80. So currently as it runs, we're not having a major issue. It could be short cycling with the compressor. It's a possibility. They are electronic thermostats but anything's possible. Let's go ahead and start checking our connections of the compressors here. Push the button to record the errors. First display is the most recent. Recall second one down. There we go. Smash the button. 82. Main power board reset outage occurred. Well that's probably because we keep resetting the breaker. Hit it again. 24. Low pressure switch is open. Now think about that. Low pressure switch will cause that to trip. If the fan would stop running the blower, your suction pressure would start to drop because you have no load going across that evaporator. We may have a fan fan in. 25. Low pressure switch two. So we have 24, 25. It's open three times during a demand. Three steps to restore compressor two. 24 back to that again. So during one demand it tripped that many times. Let's take a look at our suction pressure. Running a 60 pound suction which is about 34 degrees. So we're not we're nowhere near that should be an issue. However let's stop that. Let's see if we can stop that blower from running. I think is this one right here. It'll be a little dangerous here and see if we can pull a wire off that contactor. Pressure is still running. Look at that pressure we're on the suction side. 44. It's 60 a minute ago. That's less than a couple seconds there. See right here is S88. So you know that's the one. This is the compressor. There we're at 40. Running an 18 degree evaporator temperature. It's coming up a little bit. TXP is trying to counter it. Give it long enough to probably shut down. I mean I can't be for certain but I mean what do you know all you can do is start adding things together and start figuring it out. There must be something wrong with the heat because gas is turned off. I'm a bit surprised we don't need it very often for that. The belt I changed it to 622. Holy crap so it's been a month and a half already. It was pulling 15 amps. This is rated for 13.9. So it's going a little faster than what it should. So I must not have looked too close to that. So that's a little over SF amps 14.4. So we're just a touch over. We'll turn that down a little bit. That wouldn't cause it to well what it would cause is the motor to get too hot which it ain't really that hot and it could go off on thermal and it would shut off. But that wouldn't cause the breaker to trip. What's causing the breaker to trip? That's what I want to know. So there's 45 that's holding there. So let's go ahead shut her down to make sure she's safe and let's go ahead make sure the power's dead here. All dead on that. Let's all right so let's slow this down one turn. Okay pull a couple screws out slides out. When we loosen that up a little bit and reduce that the belt's going to be tightened back up again. It's been clanging on quite a few times. That wasn't very tight. See that? One of the reasons why these I've been starting they went back to using these over lines. Lines are great for pounding on stuff. Not that they're made for that but they work real good for it. So we got that loosened up. So we got some penetrating oil which I want to get two nuts with it because I don't want it in the place where the belt actually is going to be at. But grab these little channel locks which really ain't good for much anything other than something like that. Oh yeah somebody really got on their stupid. Yep gotta love stupid people. Gotta love them. God bless your souls. Got to spray some in the middle. We're gonna have to break some rules here. There we go. Yep took a little something but we got it. See where that puts our belt at. A little bit down in there. Now we got to wipe off that stinking oil. So get a rag on that or we can have some brake cleaner and get that off of it either way. There we go. We'll just stick that in there for now. Let's see what kind of amp draw we got. Yeah I told them that some of these pulleys needed replaced. Yeah pulleys got some good wear in there and that's probably what they did to get around half of their place. It was to squeeze it together more. I'm pretty impressed with this cheap Pittsburgh. Got a ball socket deal there and actually holds onto it. That's a pretty good job. Can't hardly go wrong on socket sets. See what the amp draw is before we get two nuts. Now we're down to 11.3 capable of 13.4 so you technically could back it up one turn maybe. Let's go ahead and kill power. Or I might have one of these motor leans here taking a dump. I mean it's just hard to tell. And I wonder too, here's the other thing, are we having problems with it blocking out and they're just turning it off to get it running again? Who knows. Getting a hold of the person who might have actually been here probably isn't gonna be very easy. So let's just go ahead and lock it up in there. I checked all this with a straight edge earlier. Here a little bit of noise in that motor. Let's spin this motor and see if it sounds sounds bad. Bearing seem fine. We're still above the groove that's wore. All right put that back together and like I said that's not the real reason. Let's take a look in here see if there's nothing. Make sure there's nothing coming apart in that area. Gonna be an investigator. That's what we're doing. They've got them all wired tied together. They're wired. Got tape on the nuts. I don't see anything there on that. Take a look some of our other high amperage type components. These compressors here were made or done in 20 according to what the date code is on them. Nice lugs on those. Nice lugs there. I mean that's not the compressors causing it. I just checked some of these contactors so we could be having phasing going on. All those are tight. It's just Hodgepodge City in here. I replaced some of these capacitors. What a Hodgepodge mess. Look for shorts. Any of the spots coming through. It's got plastic insert there. That's a Hodgepodge hot mess. Let's look at some of that garbage. Now I did replace one of the evaporator fans in one of the other units. Got some in play on that. That could be shorting. I did not tear every one of these apart. I don't feel very good. Let's see about this one here. That bad boy is hot. That is, yeah you shouldn't be having your hand on it that long. You should be able to leave your hand on it. Yeah they're probably all undersized motors which is why I got OEM motors for them. That one's fairly warm but not as bad as this one here is. Yeah that one's way way hotter. This is for the kitchen so you can't leave it off for very long. That is quite the capacitor setup right there. Capped off the extra one there because I didn't use the capacitor over there. So that, you know what, since there's a capacitor right there, I wonder if it's got double capacitors hooked up on it. That's just not good. What's bad is we don't know if that's what's causing it or not. Now this one here, they didn't use the white brown wire there. Of course it's just kind of setting there. We've got some of the wires out of there. Some of them are just still paying the butt. I'm going to get this replaced hopefully later this week. That, that is bad. That is really bad. Okay the highest leg on there on that motor is 12.6 or under 13 grand total amp which I really don't like playing with less than the water. 50 amps, 42. I'm going down there and asking some better questions to find out. Got those wire tied up. I think the way I like to do it but it's not going to dangle into other things. We can fix it when I come back. I'm going to recommend replace both these fans. The one's too hot and the bearings are running out on this one. I got to go down there and find out about this tripping breaker. It's just resetting it to make it run. Because they said they had to do it four or five times. I just can't imagine. Boom! Okay let's do it again. Boom! Let's do it again. Every hour. Yeah. Don't make a lot of sense to me. All right. Just like I figured. Bad translations, bad, bad whatever. Asked them, was you having to trip the, was you have to turn the breaker on and off to make it run or was it in the middle position? When I did it to that, not granted, you may not be talking to the same manager. Might have been three people that told another person to tool to another person that you're finally getting it but she did not believe it was in the middle position. So if that's the case, then it was going on on low pressure switch because maybe the blower motor was overamping. But as far as the condenser fan motors, if they weren't tripping, you know, they're working but they really should be replaced. I'm going to recommend that. And with the amperage being down below by an amp, we should be good there. Yeah. This is just one of the things where once again, you figure it's pretty cut and dry but it comes down to technology. You've got to make sure you question the customer right. And the reason why I didn't do it is because half the time you don't talk into the same manager. You're talking to somebody that called it in or just left a note for the next person and they don't even know either. And sometimes just waste of time to even ask or they may tell you wrong and then boom, send you on the wrong path of travel. They're trying to find the right problem. So that's what we're doing. Order and see if we can get to two motors authorized to be replaced. Right now the thing is running and the refrigerant charge looked to be fine. Reset the codes. If it comes back and it has low pressure switch again, then we know we've got a fan motor failing and we'll have to have to have it replaced if that's the case. So anyhow guys, I hope you enjoyed the video and you want to see more like it, give it a thumbs up till next time. We'll catch you on the next one. Consider subscribing. And later, so there you go, having to reset breaker every half hour. Yeah, yep. So it did say having to reset breaker every half hour. Reset because it's tripped to resetting the breaker just to reset the unit. Really would have been reset the unit. Would have been resetting the unit. So yeah.
