 So the reason why I'm here is because this cooler is running a little bit warm I just had it open a minute ago, but it's not doing real good on temperature And this is one I think we looked at the other day and kind of just set it a little bit lower the coil looks clean the Vinegarers and things like that it wouldn't surprise if it's not so it surprised me if they're not causing leaps But while I was looking at that I noticed it's a lot of ice on the walk-in freezer. So They go in here and take a look and Yeah, it's a little pack look in there. You can see that the coils can probably be frozen Same thing on the backside not looking the good Not the goodest My best guess is the defrost clocks not working right so let's go out there put that into defrost while working on the other thing See if I can get a two-for-one special peep show here And before we get into that I've got a new toy here This thing is so simple. It just makes me happy It's just amazing. What we've got here is the door jam. You can find it at door jam.com Goes around the door jam. So you don't get locked out. Well, this is one of those weird doors And it's got a kind of a difficult one to do it to I'll show you what we got to work with and how we do it These kind of doors suck Because they've got the hooky job there, which is no big deal But the problem you run into Yeah, you can hook it on there like that but They want you to stretch it All the way over there, which kind of scares me because it's just like you just got it, you know Don't really want to rip it up first day. We're gonna do that and that's what it comes out to be And I don't like doing that But even though it's stretched out the writing It works So what they usually do is they put a little piece of metal and somebody kicks it out and then you usually get trapped So it's gonna work We're just fine. This is the same cooler as I worked on a while back It's working on the walking cooler. This is on the freezer Pop this baby off here and take a look See what we got. Yeah, I would say this probably is a problem That puppy is fried to the maximum gluteus it is screwed Well, we're just gonna have to shut this thing down. I don't know what in the world happened. It's something Something just fried that I think good It looks to me like it even blew the circuit board put the circuit board there See it's left and right wise. It's split out Let's say it's probably this one There we go Yeah, we're gonna have to get that replaced. I don't think there's gonna be any fixing that What I'm doing here is looking at what terminal that is because I can't quite read that. I don't know if you can It looks a little hell of a Skelder there But from what I'm seeing it looks like it's probably the number three terminal And number three is usually your defrost I'm gonna go over here and take a peeky-poo here at this defrost heater see What I'm wondering Because the way that is Yeah, I Mean it that is that is really bad. I Mean it got loose so something happened, but I'm gonna make sure this is not like a dead short to ground Maybe that's something that was going on. I'm not sure But before I hook up a brand-new clock up to it and blow it up to I'm gonna I'm gonna make sure that It doesn't look like mice have been in here too much here. I mean you can see there's something going on here But it just I don't think a mouse got in there and caused it from what I can see go ahead and get this yanked out of there and See if we can start trimming up some of these wires and make them make them a little bit better You can see we have a little bit of splatter in there It burnt that wire feeding it which you know, they don't necessarily mean it was dead short One second could have been loose and cause it to feed like that Kind of a crazy day, you know, we just got back from Florida The two days ago it was 87 85 degrees down there and I'm here in Ohio It was 14 when we came into Detroit and here it is today. It's 54 degrees tomorrow It's gonna be 61 then at the end of the week. It's gonna be below 30 got a level high of weather. Yeah, you know Let's see if we can get this thing undone and get it juiced up with short check and resistance to ground on some of these other wires That thing got so hot. Holy crap. It just dripped Drip down there. This is a OEM clock. You see me replace this on a call a couple times ago Anyhow comparing it It's exactly the same XM3 fan So this is gonna match up to that one there What I do go ahead and copy the labels to my label are here that way. I don't have to like mark them down I'll make it a little easier We'll have that for later then then I'm gonna start testing those wires make it a little easier to test to because This one here doesn't use crimp downs. It has its own little terminal block. I'll make it a little easier I went ahead and repeated it X in four and Four there and obviously we have our three here go ahead and chop those off you can get a better look at it here You can see it's had a bad day It ate her up pretty good. You got your little jumper cable there Yeah, she definitely is crispy critter I think it just kind of reminds me purely of a loose connection because if that was a Dead short it would just blown and trip the breaker Unless we got a bad breaker. You can see these resistors here got super hot Unless we got hit with some crazy freaking surge of some sort, but this thing is toast literally I went ahead and checked resistance between three and in on there's two different ends here When I found the combination, which is the brown and this red one. Those are the heaters They came in at about 33 ohms. So it sounds about right now. I checked it both of them to ground I had nothing so it seems like we're fine. I bet we had a loose connection of some sort I'm gonna go ahead and wire it up. We'll see what happens, but you know, I did my Due diligence here to make sure that it wasn't just a you know a dead short and currently it does not appear to be now If there's something loose or something like that. We'll have to double-check for that But for right now, it's it just seems to be the issue was just maybe a loose wire or something I'm gonna truth Serious pumps down Should be able to go off that wire right here Lock so it can run either or So we got the heaters technically on right now. Let's pump them down till that pressure switch here cuts out Okay, just told the steady there Pushed a couple extra in there. Well, let it go off on timer and then we'll throw it back when we get done It's still running I got it set up to run as long as it needs to until it finally kicks out on that defrost termination switch Got most of our mist cleaned up here. I'm gonna leave this off until I'm ready to leave Which I've got to go right by it to get to my truck, but let's go downstairs. Take a look down there Yeah, it's got a ways to go yet. It's not Not there. Oh, yeah, it's it's working Looks like all the elements are working I'll just let it do its thing here for a little bit while we're doing that. Let's go over here and look at this cooler Now the other day week a month ago, whatever a Day after a month ago or two months ago whenever I was here Which gotta be careful that I cleaned the condenser you're off. Make sure it was clean Just knowing the history of how these things are It would not surprise me if it's low Hate to jump into that. It has a digital control on it Which they've already got that cranked down That's why unless the sensor is out of whack Then You know, so let's go ahead and see if we can get into here. There's a way to get this pulled out It's really nice. I think we're gonna have to move it this direction to be able to get into it You're not gonna be able to get a whole lot there We don't really have a bunch of water in the pan. Really almost none compressors Pretty hot on top hotter than I care to deal with And is running The pressure is running That's rattling enough to drive you nuts. You can tell this has been Wet in the past. Let's clean out that trap You see it's getting some accumulation there, but it's giving me every sign that it's low on refrigerant and it could be the controller, but We've had a few of those go bad. It's not been violated by anybody yet See if we can feel the suction line Yeah, it's not very cold at all It probably has a leak Let me shut her down and get a little sniffy sniff and see if we can Find a leak on this thing. Yeah, I've seen worse. It's not that bad I was able to blow through that and break it loose and then all the gunk it came out So let's go ahead and shut this thing down and see if we can get a Signal on the leak detector of any sorts It's running like it's doing slow on charge and remember that suction pressure is gonna be super super low And there's not gonna be a bunch of refrigerant in the evaporator. I mean it will be but not Not like if it was shutting off. You guys know I like infocon whether it be detect three or stratus I figured it's time to give this thing a little try. It's been sitting there for a while Got some interesting information from some of the sales guys said that this might be just a little more sensitive because there's less tubing in it Now let's take a look here and see if we can get a snifferoo You can just smell the vinegar's big time Definitely can smell the vinegars look at that, buddy Love it That's a surprise. I mean you can smell this vinegar big time I don't know what it is about the vinegars, but it makes some leak like I said Real surprise and I oh, wow, she's starting to get unhappy back here. Yeah, that's in the coil. It's doing it Yep Yep, yo I'm gonna do it with both hands that way I can be certain it's in the coil and not just one of the lines Go ahead and yank that down if we would like but What's the point? This is 134 a 12 ounces just spoke with the guy that's in charge of things He said just go ahead and recharge it probably ain't that bad Okay, so we are good to go on that I went ahead and Got a saw on tap They're on the suction line This is the way I like to do it. I swedged that quarter inch And then put it right on the suction line of the compressor a lot better than this clamp down pieces of junk And we're gonna slowly add our 12 ounces to this for me It's always easiest just to recover it start over and just weigh in the charge It's just the most accurate way to do it especially on these critically charged systems And if your suction pressure is still low after weighing in the refrigerant charge You know that you've got a cap tube restriction or a inefficient compressor or something along those lines That's why I do it and when you're only talking 12 ounces. It's just a smart way to do it All right at 12 ounces may have went a half an ounce over which since it's leaking not a humongous deal Right in there about 20 pounds that should drop here shortly. I kind of charged them at a medium pace I didn't like slug it with liquid usually we're gonna run 18-pound suction with a box that's that temperature We should just drop down or the TD that they usually talk about you're gonna have about 10 or 15 degree on some boxes when they talk about that it's the Saturation temperature minus the box temperature so the box right now is running 45 degrees so if you take your chart for 134 a and subtract 45 from 15 and then it should line up with your gauges there run about a 27 degree TD which These boxes here a lot of times they'll have higher ones Usually your walking coolers freezers are gonna usually be a 10 sometimes 15 degrees So like this one here running 42 you really need to you know get the temperature of the return side of the evaporator but That's just something to kind of go off of Delta T versus TD TD is your saturated temperature Minus your box temperature whereas an air-conditioned world. We usually do a Delta T Which is your evaporator going in versus evaporator going out with evaporators being so small like these are That's why they usually go with the TD air turbulence and things like that. It's just hard to get accurate measurements From what I'm seeing here. It looks like we're running about the same suction pressure Like I said, we wait it back to factory spec. Everything seems to be doing fine Generally if the cap tube is getting restricted it's gonna dive down there really low if not into a negative and I went ahead and put a sticker inside here that way Record and proof that yes, I told you I almost forgot. We need to check this freezer yet. Make sure it's doing okay We're up to Five and you're gonna take a peeky-poo at it looks better That one's pretty clear Got it Got that little bit right there, which We'll probably need to get that manually All right, your pump sprayers are fastest way to get this thing melted I sat there and did it with the torch the torch is just too slow And then with the new type of refrigerants that are flammable You can't use a torch and the only thing you can use is hot water So we got that done the reason for that is it will never melt on its own Most likely and then you're taking a chance of getting a call back That's why I went ahead and did it did I want to do it? No, but I don't want to have to come back later because it grows again and They know that it was frozen and they would think that either is a problem going on still or it is An existing one that was never finished. So that's why I did that now the remainder of the coil and everything is clean So I get this part done. Let's go outside button that up. Here's something to keep in mind too the safety It this one here don't let's not work. So if I would have locked on me I May not have been able to get out It's easy enough to get past it here some of the higher-end doors. You can't do that to it, but Make sure you guys don't lock yourself out because there's nobody here right now and that would have sucked I would have had to bust the door Also guys like I said, this thing is awesome. So we just pull that thing back out. She's off and Still looks like brand new that right there didn't do it a good job But you know what it's made to be used and it didn't hurt it at all. You can see some good shape That's pretty awesome Anyhow this system here. Let's go ahead and set the clock on it real quick Which we're now looking at five o'clock PM time So there's five right close enough to there and we are good to go All right guys That's gonna wrap this one up if you enjoyed the video and you want to see more like it If you would please hit that thumbs up button Consider subscribing check out our Instagram and Facebook page and until next time We'll catch you guys on the next one later
