 On our next one here, we got a milk reach-in cooler that I changed the thermostat a couple months ago. And it's cool starting back up and it's not running. They said it didn't get cold at all. First thing I wanna do is check and see whether anything is warm, which I already done did. I didn't have no heat coming off the hot gas discharge. I have a feeling that it's either not pumping or it's got a leak. What I wanna do is go ahead and do a quick check to see if we got anything that's noticeable before I tap into it and possibly contaminate the area. And that's basically what we're doing right now is just seeing if there's any major leaks because it had worked just fine prior to. And you know how that goes. You just look on it. All we're gonna do is we're gonna go ahead and tap into it and see if we're correct. And I just kinda wonder, is it a problem with the charge or what? And I bought these things a long time ago. There you go. See how this works. It's still here. Yep. You may have to make it tighter, I don't know. I'm just afraid that things will be too big. Don't be sissy. It'll be all right. It'll be all right. It's made for just recovery. I'm just doing this for test and purposes. Helen might leak her on the corners, she knows. I bought it a long time ago and I'm lucky if maybe I used it once if I even done that. So you gotta hit the power button. I'm not familiar with these things. Oh my gosh, look at that, zero it out if you want. They're never zero, because they don't have a fancy sensor in them. So we go to 404, not that it really matters for checking pressure, but all right, so we're good to go. It's got a safety glasses on. What about your hearing protection, you know? We can always go for more. Keep your face away. Even using this kneeling pad, my kneeling pad. Okay, it must not have punctured it. I don't even puncture. Yeah, I don't think you did it right. So, pop those suckers off or it's empty like we figured. Possibilities. Well, yeah. No, it's punctured it. No, it's definitely punctured. He's de minimis release them. See if we can get a pressure even though. I may not be punching it on that straighter core there. Before you try to ruin my seals. There we go. I mean, it's tight. There we go, we got three pounds of pressure. So it's got a leak. Love it. Look at that, it works just wonderful on it. It actually didn't work too bad. This guy's glass is off. Of course, they're dark so you can't see anything. So, you know. Oh, that's not good. Let's put some nitrogen on this thing and see what happens. You can see that actually punctured it pretty good. This is a big old clod fingers get out of there. And it gets shaken. Yep. You just call my fingers clod fingers. Got rude. Oh, wait. Could tell him what your name is, you know. It's Clyde. You also remember my name. It's Clyde. I don't even remember my name. I know what your name is. What is it? Starts with a C. Play hall. Winner, winner, chicken dinner. And you gotta use it to make a pond, stay full so it doesn't leak. And it takes a ton of it. So, you know. I'll give you that one, that one's pretty good. I try to be creative here. Yeah, you probably don't have a reamer in that bag, do you? Ah, we need a reamer for us at the end of your flyers as four. Oh, I know. Yeah, well, we're just gonna hook that thing on the outside anyway, so it's not a humongous deal. What we're gonna do is go ahead and get this thing tapped on there, and we'll do a pressure test on it. Now we'll see if we can find the leak with the ultrasonic there. Chances are it might be in the wall. If that's the case, there's not a whole lot you can do about it. Oh! Setting off the smoke alarm. There we go. Floaty, floaty, floaty. Don't melt that plastic on that thing. Don't melt that. There you go. It won't show that you've got your sunglasses on. I'm sorry, I went 56. So we've got, what, 155 in that thing? Boy, that's such a nice picture. Probably not wanna use my action camera anymore. Not losing yet. Not agreeing if we would've done it on the high side, we could use the pressure test timer built into the gauges. But let's see if we can hear anything. It's probably in a side wall, so we may not be able to find out a whole lot of anything. So we can't use that because there's gotta be some rodent stuff in here because it's squealing no matter where I go, but I go out into the control room where the chiller's at and stuff like that, and it goes away. It's just really super, super strong in here. So I got 155 pounds on this thing, and it's holding. What have we got going on here? You find anything on that? I was sorting about that right there. My fingertip. It looks like someone tried piercing that. I sprayed bubbles on there and it was crazy. You should be crimping it back here too, though. You're crazy. All right. Maybe we're both crazy. It could be. All right, well, let's find a sucker. I don't think it's leaking that fast. Makes me wonder. It's a 5.2 for a while. Yeah, it ain't dropped a whole lot. Let's switch it to the high side and put the timer on it. Well, that's not gonna work because we didn't put the trader core in there because I told him not to. Perhaps check your brace joint here. Doubt me. Yeah, not really. It's all right. I mean, you got like seven inches of brace on that thing. It should be all right. So, it's not really dropping much. Let me kind of see if it, it's live and direct. Of course, it just went right back up to 152. You can see right there, that's three eighths lines going up. You can see the capillary tube right there. Basically what you can do is isolate it here and pressurize the wall. Find out if it's in the cabinet, but we're not really to that point yet. However, we're not hearing anything. Can't hear anything because the ultrasonic's not on door. Now we can take it out in the parking lot and we can double check it out there. But that's not even a guarantee that you're gonna pick it up because if it's inside this insulated piping that you can't see because the light won't turn on, you're not gonna hear it if it's sitting underneath that. I'm not seeing, we should see some oil somewhere if it's leaking and I'm not seeing any oil. Wilbur has a hypothesis. He says, what happens if the capillary tube is plugged up? 100%. I suppose it's a possibility because you're not gonna back feed from the condenser into the compressor. It's gonna hold against it. So I mean, it is a possibility. It could have sucked it all up, pumped it into it. It's not gonna equalize if it's 100% plugged. Now I've never seen it completely, completely plugged like that. Spaceship was just working beforehand but I suppose anything's possible. So we're gonna go ahead and relieve the pressure off this thing. Cut that thing loose, put one on the high side and see what we get. We should have probably recorded it but we went ahead and relieved the pressure off of this thing. But it sure didn't seem like, I mean, granted, it only holds 10 ounces. Let's go ahead and cut that high side but be careful, make sure you got your safety glasses on there. So we can get frostbite today. Oh you sissies, all you get new guys are so afraid to get frostbite. Eventually your hands just go numb and you don't feel it anymore. You should wear gloves. I've been sure off a bit before already. Nope, meth busters busted. All right, let's go ahead and put one on it anyway. And you paint it on the outside, make sure you pull it in there. There you go. Oh, he's blowing stuff off. He's getting scared, he's scared now. We've got one on the high side, one on the low side. Let's go ahead and get that thing hooked up there and see what we get. You getting something? Yep. That kills that hypothesis. So wait a minute here. We know that it's now bleeding through one side to the other. Now we can't use the ultrasonic in here. Let's go ahead and just pull a vacuum on it, throw it for refrigerant and then charge it up, see if it runs and then do a leak check and then they know that there's a leak somewhere and we could look for it. If we don't find it then they know there's a leak and then we just go from there. Because I mean at this point we're kind of just wasting time. Filling a little laser today. Getting one to bring in the other comp. So we're pulling through the big line. We've got the little line there just doing the high side. Because otherwise we're pulling through the capillary tube. Either way, I just want to get it pulled down. I want to see if it holds or if it's hurt horizon. They just get it done there. We're bound off. We got well under 500. We're watching it. It's, you know, it's coming up a little bit. You can see the leak rate, it's pretty slow. But I mean, where do you think the refrigerant went? Do you think it just evaporated through the sidewalls of the copper? No, you got a leak somewhere. Is it humongous leak? Obviously not or it'd be slamming high up fast. Quick, quick, boom, boom, bang, bang. Really fast. So we're going to go ahead and recharge this thing. We're going to see what we got. Let's see if we can scan for the leak so we can find the leak. If not, they know they got a leak. School starts here in two more days and they needed to run. Just added to the list of all the other equipment that doesn't last until we're out and they can't get because everything's back-ordered. It's running right now at seven degree evaporator temperature, which, you know, this is going to run a little colder. That pressure looks a little high. We're also a warm box, which is going to drive everything else up. How are we doing on temperatures there if they hand-touch method? The coil is a lot warmer than the bottom. Well, that's good. It means we're condensing at the bottom, coming out of the liquid, going in hot gas. Yeah, that, I don't like the head pressure. It's really getting up there, but we just started it. It just seems like it's up there a little bit because it's kind of cool in here. We're probably lucky if it's 70, 72, 73, about 40 degrees over ambient. We went over by half an ounce to two and an ounce. We didn't go over a bunch. When we disconnect, we won't dump it back in. We'll just keep what's in the hoses out of it and kind of see where we're at. Just do what? All right, so it just shut off, which this is going off of skin temperature. How's the walls look? Are they starting to frost? Yep, that's good. So it's starting to frost all the way through, so it's feeding really well. Same thing down there at the bottom. So it's feeding. What we're gonna do is leave a note in there and put the date of what we did. And I would just tell them that, you know, it may last for quite a while. It may not. We can always dig into it deeper for right now. It's gonna run. But, you know, this is the very first time it's been tapped. If this is as old as what the school is, it's at least 16 years old. And they've done pretty good compared to what most things that are, you know, nowadays where they're built. So we're gonna do that. We didn't find any obvious leaks. We was able to pull it down under 500. It held for a good majority of the time. Some of it was just boiling off the refrigerant in the oil, which is normal. And, you know, it charged up right and it's getting cold. So it's gonna cycle a few times until it gets to treat box temperature. That's gonna wrap this one up. Everything else looks really good on it. I think it was just getting low and just luck of the draw. We replaced the thermostat, which the thermostat was having other issues. And we ended up, which they replaced the thermostat part of us getting here, if you remember correctly. And we got them the correct OEM thermostat and it worked fine for the rest of the season. And then, you know, summertime happened and here we are. So that's what we got guys, on to the next one. So we're on the next one. We came here to clean some ice machines and they're like, hey, cooler ain't working very well. So we got us a beverage here, milk cooler, obviously. So because I got Clayton with me, I'm gonna let him figure it out. He's probably not done too much with these, have you? Not so much specific to these, but... So nothing's running, right? That's what they said. We got power. And we got power. So what's gonna be the first thing you're gonna check? If I wanna pull this out, make sure we get power to the compressor and then I just gotta add a compressor start cord. But I don't... You don't have a start cord? I made a video on how to make one. Yeah, I did. Getting one ordered. Well, here's the thing I'm thinking, okay? What controls the compressor and the fan motor? What do I mean? Well, I'm just wondering, do we need to tear it all out of there? Can we find some of the problem faster? Kind of go with trial and elimination. So if the compressor was defective, wouldn't the condenser fan still run? I guess, yeah, it should. Okay, so why not feel both of them, see if they're hot? Maybe we're both off on thermal. Feel anything? No. Okay, so we doubt it's that. So the next thing it controls, that would probably be what? These aren't very fancy. They don't have any pressure controls. What do you mean what we're controlling? What turns it on and off? Thermostat. Yup. So where's the thermostat at? I would check a thermostat first to see if it's got power. It's probably hidden in there somewhere. It could be on the back. It's hard to say. Sometimes they'll tuck a probe up through the back and it's underneath. Oh, there it is. So what I would do to be safe is probably unplug it and then drop that down and check and see if you got power there. Once you've got that kind of isolated from all the stainless steel to short into, you should be able to check power to see whether you got power coming in and going out. I guess the other thing too would be since this has an evaporator, I didn't even know it had an evaporator. I thought it was just an evaporator plate. I thought maybe the fan would be running, but I don't think I heard even the fan running. So it might be something major killing the whole thing. No power to the stat, not even one leg. Make sure just because it ain't looping through it don't mean that it ain't got one leg possibly. Kind of go to chassis ground for make sure and then I always double check with my little light stick just as a backup. Anything? You're on probes. See you right here. That's really crazy. It ain't got nothing at all. Well, I bet you anything, we've got to get into this top panel possibly. What do we got underneath here? Take a lucky. Okay, there's main plug right there. That's where it intercepts and distributes power. There's a pan there. So let's see if we've got juice down here to this thing. Let's go in this case. Trust them, we shouldn't. Yeah, we got it on the one leg. They must have that ground wrapped around it because it's blocking the lines. So the power goes right here. See that? And it kind of makes its way up that stainless steel. I would say let's unplug it and start looking inside there. That is really odd that we're not getting anything on that one. I'm wondering if we got a block down at the bottom because that should be picking that up. This is pretty sensitive usually. That block I wonder is defective. This is where the light pan comes in handy. Let's dig into that, see if we can get that. We'll look back out. Let's see if we can get into that. There's usually a screw holding this block in right there, Phillips. See this comes in here. That intercepts and breaks one line with the thermostat. Power comes in on this terminal here and goes on up. But for us not to get anything on that one wire unless I'm getting a false alarm, makes me think that box is defective. Now to be positive, without being destructive we'd need to probe that wire. You would think what we've got going on here is you've got power wire going up on one terminal, one lead, coming back on the other and empowering that thin blade there on the left that's your hot usually. That's what I think is going on. I have a funny feeling that this is where the problem lies. You know what we could do, you could go here meter. You could go from the one side here up top to down here to see if you got continuity. That would kind of save us from having to tear everything apart. It might be a little difficult, you may have to stretch. I'd be able to put this thing up here in the middle like that and hook one lead into the bottom there and then you may have to take off your prongs there. But it should be the female socket. It's a little thinner one. You can see that we've plugged in there, the smaller blade. She'll drive one in there and then stretch that around. Go on and go on to the inside. Go on and go on in. Are you gonna try and force it through this side? That's open in the back like that? Yeah. Really? Yeah. That's pretty sad they didn't insulate it very good. Yeah, because I mean, for me to tear that thing apart, it's gonna be completely destroyed. So I don't really want to tear it apart unless we're positive. Get it on one of those terminals. So you got it on one, get on both of them? Well, you still got it on the thermostat. Okay, so the thermostat's closed. Go ahead and unplug the thermostat. You want to isolate it and get that open. You want to find out which one's your power leads. So re-probe it there and find out which one it is. So you got nothing on that one. That's probably the power coming in. The other one you should have it on. Nope. Try it on the other one. The lead that you unhooked. There you go. So that's your power lead going down. So the other one's the power coming in. So now you should be able to take the cord from the wall. Outlet. I believe the one here on the left, right there. And probe the other one there. One's neutral, one's hot. So you want to, this one right here's your hot. So go there, do the one, and then go to the other one too inside and see if you've got continuity. The other one's back there. So you don't have anything. Well, my other one is in that interceptor block. Okay. Okay, so what we want now is to take that one because we tested the one we could test. So we want to test now there to there. What you're doing is this is the power coming in. Are you following what I'm saying? So you got power coming in on this cord. It comes down to that block. Comes out of that block. Comes up to the thermostat. Comes thermostat back down on the other plug. So they're sending power on one and bringing it back on the other. That's why the neutral's separate. So you should have continuity between one of those terminals. I believe it's the one on your, that right there. And it should be the terminal that you didn't have anything on the last time. That makes no sense. So that one, I didn't have any continuity on this one last time. Well, correct, because that's your power wire. So the power's coming in from there to that side on the right. And it comes out on the other wire back down to your plug that you're plugged into. So what doesn't make sense to me is is this plugged in and then they intercepted the walk back there? Well, I'm wondering how you didn't have any voltage on that. That's what I'm wondering. Because if you've got it now with that, there's no reason why you shouldn't have voltage. And a light pin should have picked it up. So even if a neutral's busted, you still should have had some voltage there. Something don't make sense here. Either way you didn't, we ain't got a good ground reference, but even my pin should have went off. But my pin's acting a little weird. So it's something to sense. Something weird going on. So he's able to disassemble it and everything looks like it's fairly tight here. But I'm not really impressed with it. Okay, it has a crimp on there. So can't say so because people get mad about that. What we got here is basically, I ain't supposed to say basically. The people bitch because they say basically and they bitch because they say so. Why? I don't know. I don't know. Yeah, exactly. What we probably end up going to boil down to is we just need a new male plug on the end. Because look at that. Everything's pretty tight right there. You can kind of visualize what's going on here. You got one wire feeding up above to the thermostat, comes back on there and then feeds this outlet here. So everything's fine. It's gonna be that male plug. But yeah, go ahead and there she goes. Comes down to it. Looks like we just got a bad plug here. But that's smoking and stuff. That's crazy. But that looks like what happened here has gotten so warm in the past that it kind of melted that and indented it. That's not good. No good. No good. So you can understand how we did it. It's pretty simple, right? All they're doing is intercepting the power going down and coming up. I told him he's got these wires too long. So what's the verdict? The verdict is you destroyed it and it's all your fault and they're gonna take this out of your check for the next six years. Correct, that's how long it would take too. I know. No, you've got a plug that was malfunctioning and we're ordering a new one but for right now we've put a temporary one on there to get you by since you guys are starting school here real soon. Yeah, I mean it was working. Yeah, I went, whoop. Nope, nope, just defective plug. Yeah, I told him that. I said, you're gonna make this about an inch and a half. There. And he's like, no, you're crazy. Soon I'm gonna tuck all that crap in there. I can't leave that layout like that. I smell defeat. So I was learning. Yeah, yeah. Did we mess it up bad? You burnt the whole building down. This plug right here was starting to smoke on the end. Well, how long did we have that plugged in for? Last week we put them in. Yeah, it literally, it wasn't getting power up there. We was having some problems with it. We had power at the plug but wasn't getting through the wire and then finally after we checked everything out it ends up showing that the thing starts smoking. It's like, yeah, that ain't good. Oh yeah, because Becky said they plugged in like for a week. Yeah. Yeah. You got that yet there? I got things to do. Trying to find a hole. Seven days later. These are some cheap plugs, but we got it. I can't imagine why this is acting up. I mean, they got this thing kind of cranked in there. I do not like that plug either. Kind of got that, look at that. Kicked it right on. Our biggest problem is the email in plug. There was no good way to check that block so we were getting a new block. We got this mounted on the outside so it's easy to make sure it doesn't get pulled out of place. It's taped all back up. The same piece of plastic was on there. It's just not a rivet, holding it down. Just that piece of plastic, the plastic tape and it's all back in there. It's gonna work for them until then. We'll get the right UL rated plug that's OEM for it and it'll be good to go. But that's where your pin thing will come in handy. Because I mean, it basically told us right off the bat we didn't get power up here. Agreed? Yes, sir. Okay, get her done. Let's get on to the next one.
