 All right today, we're looking at a walk-in freezer. It's freezing up and we've got a coil here. It's all beat the heck Testing out our clock Which Can't tell if certain it's moving yet Also got a leak going on We pumped it down took it down to zero Maybe a pound or two above it rebraised that suction line left it vented a little bit just to case any pressure build up Got that there right now. We're just Straightening out these fins, which is a good time. This is at a school So the kids are around it quite a bit We're just kind of going through patiently trying to straighten these out as best as possible hasn't been done for ever And that's the original compressor. I thought that was a replacement, but it's an o3 compressor It's like a malfunction of a braze joint from the factory. I was able to suck it into the pockets of both Elbow there no leaks found on the pressure switch. I've got the clock like I said marked And I believe it's tracking. Yep Yeah, it's tracking see the blue mark there They had shut this off for me before I got here But it's definitely low. So I'm thinking it's probably never hitting the temperature And just run run run run run run run We're gonna wash this thing out once we get done probably go ahead and chemically clean it because it definitely is a It's a mess it's got to It's it's crammed down into those fins and you can't see nothing when you look at it from the backside Coming through this way here. You can't see squat. We'll go and look at the inside here in a little bit I just now had a chance to look closer at this defrost clock, but A little bit whopper gel there and like he said time was off I may not do you a whole lot of good. So we're gonna even those out May actually take it to three instead of the two they had They have an evaporator a walking cooler before this And that's going to get a lot of the humidity out prior to any of the issues that got going on but Probably gonna switch it to that and they got the timer set pretty high too I don't know if the defrost termination is working properly either But it sounds to me just basically accumulated in between that and the refrigerant being low Kind of gotten some progress going on here with this You can kind of see that they're a little mangoided using the My robin airbrush. I think it is it's got multiple different Heads on it. We're gonna run some chemical cleaner in it first and kind of see what we got going on This is only like two layers thick I'd rather have a gap than no gaps that way at least got some air going through the copper Did do a little something new to my freezing bag here ended up putting Washer in there in the rivet so that allows me to Zip that thing open and Everything right there on the bag There you go So it's not bad. I don't have the fancy Viper stuff all I've got is new bright Got the yellow there for my evaporators got big blue. Well, not even got big blue We're all new calgon here Cross and goes over to there that goes earlier I went ahead and put it into defrost sometimes I'm looking at the defrost heater It's sticking out of the side there for some reason Really ain't got nothing growing on the evaporator, but we definitely got something going on here at this TXV area I've not gotten good explanation of what the whole problem was since the beginning so What we fixed so far has Needed to be done, but wasn't the initial reason honestly most of the reason of what's going on Is whoever installed this used two pin of insulation. How is this just now starting to become an issue? This has been installed 2003 Um, you know, it's like come on how'd this just start You really don't know what to think when you don't get good information Finally got a mill it out there with water. There's a port there. So I should be able to check super heat So we made some adjustments to the super heat for this freezer. It was running way up there in the I 20s almost 30s area right now as you see we're running 7.2 It's fluctuating down to the mid-sixes back up to nine our box temperature Now the head pressure obviously is not hooked up. We're running right around 11 But you've been keeping the door open. So we got it all adjusted Got my suction port there got my suction line over there So just put away and it's a little bit better being right on the coil We took that defrost out. We're just going to have the two spaced out every 12 hours You can see it's feeding a lot better than what it was. We got all that out There was a little piece in that fan motor there. We got that fixed. It's looking a lot better So we're running a 31 degree super heat We're not frosting up like we were earlier in theory. I mean it was starving it. Yeah, we're Check our sight. Last make sure we're still cool. We are sometimes that'll change on you after you get the Charged sex now it's letting more through the coil got our clock back to Every 12 hours. We'll go ahead and get that set for 2 30. Go ahead It'll go into a defrost which will make up for us having that door open so much We'll do that here shortly. We have about 32 minutes area. I think that's gonna be fine She's satisfied and she's ready to go the timer set up coil looks a lot better than what it did You can actually see some stuff getting through it We've got the super heat set correctly. We were good out here on the super heat Like I said, she must maintain that Minimum of 20 according to Copeland lines not running just cold. We're maybe going to fix this issue It's not, you know, still ain't the right insulation. I told him to save your money Check it out. Make sure that it's freezing up still and if it It does fine. We'll have the insulators come out and do it Otherwise everything's a lot better and what it was we got the super heat set We got the leak fixed on the suction line. We got the coil cleaned the coils straightened And everything's working pretty good. We got that ice off the end of the coils. All right, so we got us a walk-in cooler here It's starting to freeze a little bit there You can see it a little bit there But it's really bad over here Over here on this side Definitely not good So I don't know if it's just low on charge. It's defrost issue. It's kind of weird that only one side did it Okay, this old beast here. Let's see what's going on with the old larkin Looks like less either full or it's empty one or the other. We got it open. I went ahead and marked the clock I figured it was maybe bad. It's getting ready to go into a defrost. It can do Looks like I got a 20 minute one. These are heated coil defrost because they are beer cooler So we're gonna go ahead that turns really hard But it's turning No, that was a lot harder than it probably should have been Let's let it pump down. They got an interlock right here You new guys interlock basically they got a circuit that's not quite capable of handling everything at one time So what they'll do is they'll wait till this contactor for the compressor shuts off Once it does it allow the power to loop up into the contactor that powers the electric strips When you're doing your maintenance is I like to write down the amperages that I have when it's working right That way like today, we'll check it and we'll see whether or not it's the same If you lose an element, obviously, it's gonna be a lot lower. See if this thing pumps down and shuts off here Now if it's not energized It should be pumping down I know this sometimes So we do have a full sight glass. I had a there we go So that one dropped out that one kicked in Go ahead and check our amp draw here First leg there as we're looking at it 15.1 We have 15.4 down there going to the second leg And we're at 30 It's 30.6. That's good. And then going to the last leg Right around 19.8. We had 28.1. That would have been done with my other meter So all the heaters seem to be working. See how that works out kind of nice Just for giggles checking the other ones here just to see if anything's different Our termination is kicking out. Maybe what's happening now that we're into summer months May take that up to 30 minutes Now that the humidity is getting higher that the cooler is getting left open longer I can't remember if I changed that. I don't think I did but that seems awful short And we're going to leave it a little high just because we need to eat it to melt anyhow Coils could be a little dirty too. It could be an airflow issue For both of them to both do it at the same time. It makes me think it's going to be a defrost issue Looking through here into the condenser To make sure our coil is clean, which I can see some light Right there's some right there bottom left corner. There's some there's some there's some so I I've washed washed washed washed these out Really good in the past this one here is just riddled Not doing so great I mean more swash that thing out. So not even a couple minutes and it just kicked out. Okay pressure switch must have uh came on Thought we were going to get somewhere unless it's going to wrap its cycle back and forth like that We need to see where Our pressure's at maybe rising up. Maybe we're leaking through the valve hard to say It looks like we're holding right in there at about seven pounds area, which is fine. This is r-22 like I said Be very very quiet. He's sleeping sleeping right now. It's starting to melt. You can hear it ticking I probably can't quite scrape it off right now, but The one side looks really nice This may have to get the old sprayer out. I want to get some hot water off the water heater here And it's not been drained forever and it's not wanting to come out now So this is great. So that means it's plug full of crud And I'll probably drip now non-stop, which is wonderful. No good deed goes unpunished my friends And it stopped Got our handy-dandy pump sprayer and so far I've gotten the top loose And we're just kind of working our way through once I get that broke off and kind of going to work my way down into the coil the Inside coils definitely got crud in there. So you can't just go by some of it The heater's working pretty good. I'm just trying to speed it up I've got three grocery stores that have called in And it looks like I might get out a couple of them because it's just false alarm type stuff, but I can't spend a whole lot of time here just because you don't know and they're all in opposite directions Trying to speed this up as much as possible that defrost heater is going to definitely be set at least 35 minutes. I think that Would probably do us good then I grazed it while we were doing our thing here and it's not kicked out yet. So It appears to me that you know, we're definitely keeping our defrost termination switch Engaged in the heating process. I don't think it's an issue with that All right, so cut all out on me. I think the defrost limit was happy. So we're gonna have to unhook X Maybe it wasn't happy just timed out Before I end up forgetting I think I'm gonna set that down to 32 It's got termination. I'm not as worried about it. It's pumping down on the low side, but We can tweak that a little bit here in a little bit the uh It's staying engaged. We're gonna finish melting that out cleaning some of this muck Crap off the freaking fan blades. It's kind of ridiculous So, um, we've got ice still on the inside In there. So we've just about got most of it out. I've melted some of that there. You can see a little bit of dirt It's not horrid We've already gotten the outside edge corners here. The ears are still kicking Just basically working our way around same thing over here it's Out in there almost almost completely gone longer defrost. I think it's going to be all we need good progress so far We're running about a 24 degree of app We've got full solid side glass. Coil is not too bad. Today's saturday. This is an overtime call We're not going to spend a lot of time on this so we can always catch it on another trip Clock seems to be tracking. Uh, there's a possibility that it might be malfunctioning But it kicked out sometimes it's harder to get into defrost than it is to get out of it We wanted to make sure that it was 250 volts We've got 120 This is a neutral going over to Our line over there. So this has a dedicated neutral the clock 240 volt this one is weird oddities where they have a neutral wire ran out here Giggles kick it out recheck it just to make certain it ain't nothing weird that we got some some weirdness going on I'm still 120 That's uh, we're going to screw up our timing up I would say it's probably going to make your Timing go about twice as long. It'd be about every 12 hours But we're going to go ahead and get that changed But the 230 volt clock away We're getting 120 volt on there. Everything else is looking pretty good. I know I've had problems with this thing in the past here It's full and the coils Don't believe are too bad on it Yeah, I worse this one out multiple directions chemical and The whole nine yards on that and it got it up We're working fairly well. A lot of this couldn't just really tired and Ready to go home to the promised lands That's going to wrap this one up guys We'll probably tack this on with another video But if you guys enjoyed it and you want to see more like it Make sure you subscribe give it a thumbs up and we will catch you guys on the next one.
