 All right, so we've got us a nice machine here that they've tried cleaning and doing some Rub-a-dub on it to get it to work and it's not working. So let's go take a look and see what we've got going on. It hopefully won't need any more of that. There's nothing better than walking in and seeing the covers off. Really reassures you. I've seen worse. And I'm getting up there in the top corners. Got a lot of water in there. Makes me wonder what's everything in place. Same as the big. I can check if we plug it in. You can see the condenser coils clean. I've worked on this one on another video prior to. It's been a while since I've been here. I kind of showed them about as much to maintain it so that I don't have to do the small things that they can easily do. So it's a nice cord. It's wired directly. It's an expensive pigtail. All right. So what have we got going on here? Talk to me. I guess sump empty. All right, good deal. Sump. We don't need to, all right, sump full so we know the water switch works. I like to just kind of feel around and listen to what's going on. So we're in the harvest. At least what this one starts out in. Manual harvest. And notice the fan's not kicking on very much for very long. That's on and off awfully quick, which usually means the fan switches out or it's low on charge. It's fairly warm back here but really shouldn't be cycling off. My suction line is not cold at all. My line going into the evaporator plate is fairly cold. Grab some gauges. You know, we want to do the hand touch method before we just go slapping gauges on it and pulling the refrigerant in and out of it. I have that computer warranty until 2019. All right, so let's go grab some gauges. Something's not right with that fan. We got 490 pounds of pressure there. That's not good. Let's bleed our hoses out a little bit here. We can dump what we have back in there. But obviously we have a fan switch that's likely bad here. So let's go ahead and kill the power to it and get this cover off. Yeah, unless we can see where the switch is at. Which I think is right. At least it can be an easy one. Ouch, cold darn it's freaking hot right here. So what I'll do is I'll put a piggyback jumper on there, stick it back on there so it doesn't short into anything and then we'll order a new pressure switch for it. Had to use these just the other day. Now this fan, doing what's doing, it can still kill the fan when it goes into harvest because it's going to come out of the relay for that part but far as the pressure being high enough it's gonna run. And I'll at least get it going. I don't know if they're using this for football or what. So may not be a big deal that it even runs. There's the harvest again, which it's 84 degrees back here, 85. So that explains that a little bit. There we go, trick it again. So see the fan's off right now and we're in harvest. So the fan's still being controlled by the control board. The fan motor's not hot, it freely spins. That's a 50 watt motor if I remember correctly. So it just finally went into freeze, fan came on immediately, pressures are doing their thing. So let's see how this thing does now. I don't know if they've missed with any disc sensors or anything like that. So we've got to make sure that everything's working the way it should. Otherwise, our name will be on it after we leave. I think they just pour the stuff in with all of the day. Let's go ahead and close this back up so we don't let all that heat in there and we've got accurate reading. Been a while since I've done scouts one. I always get confused when I do that though. So let's go ahead and start the stopwatch. Watch us for a touch and see where we're at. Fan's holding in there at about 289, which is 114, it's about 90 degrees now. I have a little more accurate if you do it back here. It's 114, about 24 degrees, 23 degrees over ambient. Sounds about right for head pressure. Then our abap's dropping. Pressures are starting to steady out here a little bit. We're on about a six degree of abap. We're at about 18, 19 minutes. So technically it'd be about 20 because I didn't start this immediately. Need to check and see what our thickness is right now. We gotta be getting close. I will say you don't want to try to check that with that cover off. It will not work very good most of the time. Too bad. You can hear some clicking. So this should be getting ready to go into a harvest. Yeah, right about now. I don't like it. Going too far and all that clicking. Usually that's likely to tear apart your plates in here and then start losing the center dividers and stuff which will cause harvest issues and things like that. When I was taking the cover off, this is such a poor design compared to the main sidewalk. You can't get in there to adjust it. So when I did that, it happened to go right into defrost when I had the cover off, which canceled it out. So we're gonna force this into harvest now. Let's stop the watch and we set it. These guys are not as critical about their timing as what some of them are. You can see the fans shut off during harvest. So it doesn't really matter that we've tied it solid like they did because the power's being killed in the board before it gets to the switch. And we're building up some heat here. You can hear the water being added and they're still running the water across the coil. And there it goes. Very good. I'm thinking we're probably fine. They've cleaned it and honestly, it don't look too bad. I mean, I'm kind of anal about the way I do stuff. But don't look too bad. Just order that switch and then we'll have to come back. Let's get on to the next call. And this is gonna sound like a really dumb tip, but this is primarily for the newer guys. What I usually do, and you've seen me do it, when I hook my hoses up, I will bleed suction side to the yellow hose, then I will close it. I'll open up my high side, bleed it to the yellow hose and I'll seal it by closing it. All air has been pushed out of the system, completely sealed up. Now I'm done. Critically charged system. Yeah, not really. Not near as much as with some of Mars, 21 ounces. That's not three ounces or two ounces. So from right here, we're coming off hot gas. So there's not gonna be that much. Gas is nowhere near what liquid is. So hot gas, we're gonna dump it into the suction side, watch our lines drop down. I like the sight glass because you can see what's going on down here. Once that's done, I like to disconnect. Everything's been dumped back into the system. I like to valve off. I prefer yellow jacket. There's some of the best hoses out there. And I prefer the ball valve. So right there, the most part's the most you're gonna lose other than that little bit there. So that's a 10th of an ounce probably if that. So that's how I unhook my hoses. That's how I get away using six foot hoses without worrying about losing things. That's how I switch between refrigerants without cross-contaminating one refrigerant to the other, which if you know anything about these blends, half these refrigerants are blended with 34A, 134A, one, two, three, 32, all kinds of different refrigerants. But obviously they've got the license to do that. So anyhow, that's how I do it. And I thought I'd throw that in there real quick. Like I said, we're out of here. Let's get on to the next one. We're back to change out that pressure switch here that we found bad. So we could pinch it off, but a lot of times it's so difficult to get that pinch off tool in there. And it usually looks ratty. Go ahead and just pull the refrigerant out. We've got our new switch right here and even the switch. Generally what I end up having to do is sledge it out. So another reason why I prefer just to unswet it and change it. So that's what we got going on. Unfortunately, there's not a whole lot you can do there. Put the oil and it's really not a whole lot you can do far as nitrogen because it's not like it's going to flow through this thing. So we're just going to get this thing heated back up, slide it into place. We want to make sure you don't overheat your end here. Probably have enough to do that, no problem. We did solder here for the switch just in case. For the most part, it shouldn't be too hot. Yeah, it's not too bad. There's our jumper we had. So we're going to go ahead and take that off, obviously. All right, so all we got to do is get the filter dryer changed and pull it back on it. We went ahead and pulled the vacuum on it, got the filter dryer changed, got it recharged back up. 21 ounces, everything's zeroed off. Can plug this thing back in and make sure it still runs. Pressure switch is coming up. I think about 250 area, 230. A little bit lower than the main its walk, I see. Yeah, probably help if we put it on the right refrigerant. Very sure as our temperature drops, start to freeze. Man hasn't had to kick off once yet. Staying in that mid 90s, high 90s. So we're all set to go. We'll wrap this one up. All right, so we've got us a freezer here. There's quite a few of them in this building. So we're just going to check it and see what's going on. But basically the system's not running. Just got here. Let's take a look and see what's not getting power and why. Let's see what we got here. Does not look like it's tripped. Switches on. It's not in defrost. Okay, what do we got here? 227, 235. 235 and 233. So we've got the juice to that point. No power indicator there. Fox getting 235. Might be one of our switches here. It's the most logical. We're not getting any call or to run the coil. So it's not getting a thermostat call, most likely. Our evaporator fans are calling. Each one of them's got power on them. We've got our evaporator fans. Our block to theirs, defrost here, which are these two here. Pump down switch. We need to find our thermostat. High pressure, low pressure. And we'll find solenoid on five. Five goes out and six comes back. So if they wired it that way, there's five. All right, we got our solenoid here on seven and five. Which when we go over there, we check for a voltage. Seven is right. Here you can see the number. And five is right there to the left of it. And you've got nothing at all. So you check your thermostat here, which is between five and six. So you go here to five and six. And we're closed on that circuit. So after that thermostat, it comes up, goes to the defrost timer. We just follow it along. Should come out of the defrost timer. Comes over to C6, which is contactor. So maybe our contactor's not pulling in. Let's see if we've got power on our contactor at C6, which is out of four. This is all live, so you don't wanna get in there and play too much. Got the protected leads here, so we don't have any arc flash, which luckily this is only 200 and some odd volts. We have no voltage to the contactor, so it's not an issue with the contactor as of now. So backtrack off of that. Let's go up to number four. Let's go to N to four. I have power coming from N to four, which is up here. So N to four, get 235 volts, which means we're getting power out of that. So four, which all these wires the same color, which is really wonderful. So come out of four. It should come straight down to the contactor. So according to that, we got one coming down to six. You got another one coming down to the contactor. So depending on where that's at, that should be, one goes over to six. I bet you that's it right there. This one here, somebody's already kind of cut these up. So it's kind of crazy. I get too many dang wires all bundled up. So I tracked it down. One comes down to the fans. The other one comes down to number six, which is what we said. Get this out on six, which should go to our thermostat. So we've got power coming down to here, two N. So we got 236 there. So we got power going out to, which number six should be our thermostat going out. Should be coming back on five, which is this one here. So we can go here on five, two N. 236 coming back on that. So that's kind of crazy. That is number six and number seven there. Six and seven's on the same one. So one's going to liquid line solenoid, which looks like it's this one right here. I wish we could have about seven more red wires. So there's liquid line solenoid on the one. And the other one is right here, which comes over, goes to there, which we've already checked that. We don't have any power to our oil safety there, which is right here. The oil safety is getting power from the compressor module, which is normally open. I've just verified I have power on 16 and 15. Obviously I'm not getting power back from the module. For some reason, the module is tripped. Got to see if the compressor's hot. I haven't dug into that far, so we're just kind of going through the wiring, but we should be able to check power on F2 and 14. Which 14 should be coming back to probably up here, I bet you. Right there's 14. So in line, so let's go to line there to compressor two or to fuse number two. We actually got power there. Compressor module here, we verified that we have power on T1 and T2, and we are open on M1, M2. So we'll come down here to this. Like I said, we've made sure to see if we got power to that. We got it going to it, but we don't have it coming out of it. So the module's tripped for some reason. Now I've got to find out why it's tripped. If we got a sensor inside that's not happy, because basically, I don't know if they show, yeah, they really don't show anything in the compressor module where it goes to. So that kind of turns into something different. So we've got something causing that module to be open. I found the people who are finally, I wasn't looking very hard. We've got it right here on the back side of the cover, blind, 500 to 2400 ohms is what it should be between common. So here is common coming down, feeding all these thermistors, and then goes back to each one as one, as two, as three. So we've got common there. This one right here, I had 1700, 1728. And then here we had 1948. And I believe this other one was 1948, 1980. So we are technically where we should be at and it's not closing. We're gonna see if we can get us a new protector here. I'm big into making sure you're positive on your diagnosis so that you can pick up any other parts. So what I went ahead and did is jumped it out just momentarily, flipped on the power, it kicked right on. So it tells us we don't have any other components that I can think of that are acting up. That way, since I'm going to the supply house, I don't wanna go get that and then have to come right back again and go back again, back and forth wasting time. So we got our new module kit here. Got the power back off. I went ahead and turned it back on so that it can circulate the cold air in the room. No sense of having it completely, not running, circulating. In Germany, but for the most part, the same thing. So we've got two wires here, which were for the voltage coming in, L1, L2. So we'll just copy that right there. They do not give you hardly any extra room whatsoever. And all that is is a bunch of thermistors and the windings. And it's monitoring that temperature and based off of the resistance, it knows what that temperature is and that's when it decides to call it quits or not. And since this is a very expensive little protector, I am gonna do this by hand because I don't want to take a chance of cracking the shell or anything, which it probably won't, but I ain't taking a chance. And that right there. I'll just make sure some of these other wires here are nice and tight. We've already checked the resistance of the presser and made sure nothing was shorted to ground, things like that. And voltage-wise, this is capable of doing both, I believe, 120 or 220 volts, which that connection's the same for either or, 2208 and 240. Music to my ears to this big old monster building warehouse. And for a little bit, make sure it doesn't flash off. But I was here the other day and I checked the sight glasses when I was trying to find out which unit it was. And they were all solid then, so they should be all right. So far, everything looks really good. Kinda shut off. That way we know that part's working. And she shuts off. Good deal. Okay, let her rip. You guys, it's gonna wrap this one up. I'm gonna probably add this on with another video. So if it ain't added on with another video, make sure to like, share, and subscribe. Until next time, we'll catch you guys on the next one.
