I went ahead and scouted this out. Well, we've got the system we haven't worked on. So it's kind of new to us, I believe, far as happened to work on it lately. The initial problem was the customer had this particular evaporator freeze up. So what she did was turned off the fans, which these are both together in parallel and the system continued to run. They left it off for a week and here's what happened. So to say the least, it got worse than what it was originally. So what I've done is gone up on the roof, flipped off, pumped the system down by putting it into a defrost and then shut the power off to it. We got one fan out here. We've got, I believe, another fan here. That looked like it wasn't one of these didn't look like they were spinning right. They might be working now, but we're completely froze up inside here. We've got milk, which is their biggest concern right now because they just got a delivery. But we're going to get this milk moved into another cooler. Well, they have two other coolers over here that were turned off. And so I'm up on the roof and I look at this cooler here and it's turned on pushing straight reports and there's no refrigerant. So this cooler is not going to run. And we've got other problems to fry before we would even consider screen with that and they haven't been using it anyway. So we have a freezer. So flipped on the freezer and the freezer runs. So what we end up doing is going in and flipping the thermostat up to 35 degrees. Moving the defrost clock down to 20 minutes because it's a heated defrost and that's going to be good enough to get them by to hold their milk. And it was holding at 35 and with the door open to hit to 40. So we're going to be fine there from now while we're working to get that going. That's the start of what I'm running into. I couldn't find the key. Luckily, a little piece of duct tape really kills that siren and we got that wedged. We're going to do is we're going to try to break off some of this ice from the bottom because I really don't want it all melting all over the floor. As you can see, it's already starting to melt pretty quick. I'm going to grab a trash can, dump it into the trash can, see if we can knock that loose and then then we'll melt the rest of water. We went ahead and knocked some of the ice off. Knock some of the ice off there. You got to be careful though, because you don't want to puncture anything or create more problems. Still got more to get off there yet. But I'm trying to get that done as quick as possible because it's making a mess. They never put floor drains anywhere near here, which just makes it more difficult. We could have put a tarp on this, but I usually don't run into this that often. I am going to figure out a way to make sure these stupid switches are gone. There's no reason they should have had these. Unfortunately, these should have been wired with a solenoid that if you're going to shut down the fans, you need to shut the solenoid off and then you shut down the refrigeration system. There's no reason to have these on a cooler anyway. I see it sometimes on a freezer, but even then you need to wire it on so it kills the solenoid at the same time. That way the system can pump down and then the system shuts down, things get warm and you go like, oh man, something's not working. Instead of just letting it run, run, run, run. Melting it away slowly here. We've got most of it knocked off the bottom. Oops, got most of it knocked off the bottom. Once we get the back down, we'll go ahead and get the inside done. I got the fans shut back off. As soon as I can get it to release from the coil and just kind of snap it loose. And then that way, because I'm not trying to melt it completely, I can bump it a little bit and make it pop out great. Otherwise you can spend all day here. I've been doing this kind of throttle on it and shooting mainly at an angle so it doesn't go too far into the coil. That way most of it hits the outside. I've already gotten one piece to snap off, literally just bumping it. And it doesn't hurt the coil as long as you're going in flat all together. Then I thrown it in the trash. But yeah, we got the back about completely done. And then we got a little bit in the front to do at the bottom there. We'll get that here in a moment. I noticed this fan here slows to shut off. So we're going to replace that one. And I already got one that's completely dead down there. We'll get that one back all done. Everything's fine. Kind of rinsing off some coil. See a little bit of dirt there. Not horrible, but definitely got a little bit there. I don't think that was enough to slow down air flow to create what we got going on here. I think we got defrost issues. It was set for like, I think 30 minutes total. And if they're trying to make this into a beer cave type style thing, that's not going to be long enough. Usually we got to go somewhere between 45 and 60 minutes of timed off defrost, but meaning it just doesn't run the compressor section. We got that. We're going to pull a couple of these fan shrouds and get in behind there and you got to make sure that there's nothing in between in the coils themselves because it will hide there and you'll think you got it and you don't. Well, you definitely got some ice out of there. The Klein flip bit here. Works out perfect for making that quicker and it's magnetic. So it kind of holds it right there for you. All right. So we were able to get the last bit of it. If I can sneak behind here and not get it on the motor, I get it in here this way. I need to really watch out for the motor. I'll go ahead and yank it out. But literally was able to pull that out without bending it, speeding it up. Now what I did notice here while I was working on that was when I seen this one shut off before it it there. You can see that it's it's sometimes catching and stopping. This one here just an easy turn. Look how long it goes. Just an easy turn. This one here easy turn. This one stops that when they're still going and this one here stuck. So we're going to get these replaced. I'm going to check this coil here. We'll probably spray it off just to be safe. All right, broken loose with some pliers there. Get these out of here while I'm in here. I'm going to look around and see if there's any wires that are getting close to shorten into anything. These were pretty well wire tied so they wouldn't. This was wire tied to this wire right here. The nice big nuts here probably won't fit the new motor. So we'll have to use the small ones that come with the motor replacement motor and a little stand there for us. Okay, got it out. Little Fasco motor looks like it's 115 volt. 20th horsepower. You can see the oil that had leaked out of it. It does not want to turn. So it's definitely got some issues there. This is where I like regular keys like this with the extension. How I can break them loose. It seems like it's easier. There we go. There we go. And this one here would not spin at all. Sometimes you can just get on there with your linemen's, break those loose like that, and take off the way by fingers. And since they just got in deliveries, it works out great for a little table. What we use is the Rescu 9662s. Pretty much about the same motor. It's reversible rotation. You carry 230 volt version of it. And like I said, the capacitor might need switch to the front. It's hard to say if I do, I can just undo it from there and move it to the front. It does come with both plugs. I think it takes that wider one. So I'll tape that together so it won't fall out. And rotation will just see what it is when we get in there. All right. What I ended up doing is just trimming off the nubs on the back side. I got plenty of room back here. Okay, I went ahead and taped that together so it doesn't pull apart. Got to leave that adapter on there because it's a wider plug. Then I'll put a wire tie on that so that it can unplug itself. And strap that down to these other wires. Flip it on real quick. See what my rotation is. See what's going on away. They had a do not turn off the fan thing there. Some of them make stickers. And that way, I don't have to unwire it. And then they will at least know because they didn't know any different. So there we go. Switches two wires back in. We should be good to go there. Okay. We was able to wire tie it there and that won't pull out from there. Got that reversed. And now just put our blade on. So we got them all together. Let's get them on. Make sure all the fans are going the right direction at the running. They're all blowing. They're all blowing. We're good to go. I went ahead and washed the grills. Washed, washed, washed, whatever. Clean that up. Those ones are going to need a little bit yet. Those are all got cleaned up because I take them all apart. And so we should be ready to adjust our defrost and check operation. See if our cyclist is full. I'm not sure exactly why this froze up originally other than just one fan motor, which I find that kind of hard to believe. However, we're going to check the thermostat there, which who knows what that's set at. Like it's set for 35 degrees, which is perfect. I'll give us enough for a traditional off cycle defrost naturally. And then the defrost clock will do the rest. Let's go ahead and go upstairs and see what we got going on up there. They had high pressure port on there for some reason. And let's just see how this things feed and see if there's maybe a TXV issue, something like that. Who knows? I went ahead and repositioned the bulb over back behind here. So that way it'll have the air coming through and that would be more accurate than set and dead in the middle. I usually like to see it either up in this corner on the back corner close to it, bulb pointing down with a refrigerant line coming into the top. And I already go horizontal, which is what I did there. Yeah, I'm on the conduit, which normally would not be a good idea, but all this conduit is inside here. It keeps it away from the wall and that's not an outside wall anyhow. So let's go up on the roof. All right. So here's the condenser. Like I said, we put it into defrost to pump down with all the refrigerants up here and then shut it off. I didn't want to forget the defrost already taking them up to 45 minutes a piece, kicking it on pressure switch kicked in. It should be about ready to release and roll. Seven forty five. Let's set that up. She goes in defrost when I do it. It's a little sticky. You could have a defrost clock going bad, which I think I'm going to replace it. I got to check the contactor yet. You can see a lot of the parking marks there. Really happy with a lot of this stuff. Got wires with like the coating. I think that's just the outside coating that started to crack wire nuts there that's been punched instead of squeezed and the insulation on those is cracking. The sight glass is staying cool so far. Hopefully we don't have to mess with that because like I said, this is not the refrigerator we use. So that's what we're starting with. I'm going to go ahead and put it into a defrost. That way we can go ahead and start checking some of these electrical connections. Like look inside here at the contactor a little closer. All right. It shut off. Chill power. Get in there and look at this. Points a little better. They definitely are a little pitted like our capacitor here too while we're at it since it's just kind of hanging around three factory wiring with a wire tie. All right. I thought this capacitor felt a little warm. We isolated one leg 5.9. I don't need to do the math. It's that's weak. So I get that changed. Got a new clock ready to go. Got a new contactor and new capacitor. New capacitor here. We'll make sure it's all right. Comes in at 7.7. Got the new contactor mounted up. They had some jumpers there. I went ahead and snipped off the ends and just connected to under one spade terminal there on that. And all we got to do now is just change the clock. But it should be a pretty easy swap out. Just get that popped into place. Got the wire nuts there that we're looking a little ratty got them taped up. Checked all this wiring. It's just that plastic clear coat that's cracking. The main insulator is fine. Everything in here looks to be good. It's all tight and tidy. We're going to go ahead and kick her back on. I've got the clock set up for 345 minute defrost off cycle defrost screens on good. Got the new contactor. Got the capacitor mounted there. Used a heavier wire tie than that traditional one. It's a pretty heavy one. It should last at least a couple of years. But we're going to head into the stropping temp. See where our cyclist is at fan cycle control. Looks like it might be a little out of whack, but I really don't want to try to adjust that today. But for the most part we've got most of all our base is covered. We had like I said that clock here that is it does not want to turn. I mean it you can see the jump there. I mean it's like I'm trying really hard to turn it. It's that thing's junk logical solution. Here's the defrost clock was sticking. Sometimes it probably would work. Sometimes it wouldn't then when they turned the power off that just compounded the problem. We're going to put it in defrost to make sure it times out and shuts down with this new clock. Nothing worse than finding out tonight over time. But it's not running correctly. All right. Good deal set up for the clocks time. You can see how easy this turns. I got just one finger not better. So it'll go into a defrost here on one. We got about an hour or something before it needs to drop down. I'm going to put in mind it's skipping that. You know what? I've actually got four of them here by accident. Let's switch that to three. There we go. Normally two is all we need, but in this case here because they're running the beer and they may decide to try to go colder. We need to try to get as much of a can. This is not a heated defrost. Like I said, it's just timed off. So all you're doing is using the room temperature to fall out that coil. That's why you can't go below 32 and even at 33. I mean, you just not enough heat there to really melt the coil anytime soon. It's just longer. You're going to have to go the colder you're running it. So it's pulling pretty good on that. I mean, could we spend time here? Clean coils and all that stuff. Well, normally we do a lot of PM stuff for these people but I've never been to this store. So I don't know if they're going to have us do a PM on this one or not. But for right now it appears it's all right unless I dig in there a little further and find dirt trapped in there. It's probably going to be let go. So far we're still staying solid here. We ain't at box temp yet and it's not cold out but one of the things where, you know, it may need more but I can't stay here all day. We've been here for a while as it is. Coil and stuff took a while. Going to go down here and watch to see how the box temp is dropping. So far everything looks like it should be good to go. Got to make sure there's no other hidden problems. Went through. Notice dies off by a little bit. My addition was a little off. So like I said, every eight hours we'll be got to set for 45 minutes. I'm going to jump it up an hour. It's not going to hurt nothing. We're going to fall. Well, I don't know if we're going to fall back and fall or not at the time. I thought they voted that out. Not sure. Anyhow, whatever. I don't want this thing going into a 45 minute off cycle here in less than 45 minutes. This thing needs to run nonstop. Get that box down to temp. All right, so hopefully that sticker there which they have writing on that one but they did not have it on this one down here. So got it on both. It still leaves it so we can do our work and kill the fans simple. That way, you know, they've been told they do something that causes that and it's their own problem. So recap we've done thermostat moved the bulb over to here replaced bad fan motor here bad fan motor over there replaced contactor up on the roof defrost clock on the roof and weak capacitor on the roof. Condenser coil could be used probably a wash in wouldn't hurt nothing but I think we're going to try to get that on a PM if not the whole store looks like it needs a PM. I think it's a new store they acquired. So currently right now let's start to drop the temp. All right, so we had a little bit of ice left over from before. Feels like it's feeding pretty good. There's super high humidity in here because all the water on the floor. We got warm coming in getting cold as it goes through which is normal. Feels cold here. Looks like they're all feeding so we're probably fine there. Don't know if it'd be worthwhile to check it over with a super heat or not. So we looked at that one's distributor tube and now we're looking at this one here. Seems to be feeding about the same way. You know, it wouldn't surprise me. Feels warm that they probably just dumped that R22 substitute crap in there and didn't recheck their super heat. It was originally R22. So, you know, you've got to ask yourself why did they have to change? Have you ever had a leak? Is it a continuous leaker? You know, it's one of them things where I don't have a whole lot of information and I don't think anybody here really knows much about what's going on either. I'm going to just let it go for right now. I mentioned it on the paperwork that we may need to stop back and check that. And that way I'm not spending more time here than what I need to. The thermos thermometer here doesn't look like that works very well. I don't know if it's broke off or what. Yep, it's broke off. So that's bad. That's not very useful. Let's go look at that freezer that I used for a cooler while it's temporarily working on this and we can shut that thing down. They can move the milk back in there. Looks like the walk-in freezer's right here. Let's see if that's the one. Yep, it turned off. It's holding pretty good at temperature. They were just inside here. So, yeah. Just one of them things. So that's, there's that. I want to ask them if they want to use it as a cooler or whatever, which is fine. The thing beside it is a cooler, but it would give them extra room for cooler. But I don't know if they really need it or not. I'm going to let them decide on that. They want to use that freezer for a freezer. So we're going to go over there and turn that back up. I wanted to check the site last a little more time. We're starting to get some bubbles. That's not good. That's what I was afraid of. That's probably other issues. Probably has a leak. It just, everything just piles on. This is what happens when you let everything just go and you don't maintain it. So this is the freeze. We're going to put this back to the 35 minute, 35, almost 40 minute defrost. That way we've got it back to normal and they can turn it down at the thermostat. Right now they still got that milk in there. This just has a regular old traditional clock, honestly, I like better. They work better. They last longer. They don't care about dust and dirt and all that. So set up about 37 minutes area there. It's got a termination on it. Everything in there looks rough. That's on, we'll mark it on the outside so we know it's freezer. It was a little hard to decipher it there with the way that's all mangoided. All right, so it went solid again. I'm going to just tell them that we probably need to do a leak surge possibly on it. I'm going to see if we have any history on this thing. I mean, for the most part, I mean, I've been here for quite a while getting everything done. I don't want to spend a lot of time then they question the bill. The system seems to be working pretty good right now. Those TXVs could be adjusted. I can't really set the super heat right now with the box not being at temperature. It always changes once it gets to temp. At this point, I'm going to wrap this thing up and then we just come back if we need to come back.
