 All right, so we got a walking cooler here that had been freezing up the coil. And it's been about a week since it's happened. They turned it up, thawed it out. So we just got here, luckin' it over. So far, the sight glass seems to be full, but you can really feel some massive heat out of it. So I'm gonna probably go ahead and clean this coil off. It's lookin' a little bit dirty, not bad. But just lookin' at the sight glass, I'm kinda curious once it's clean, if that'll give me any issues. But I'm gonna go ahead and clean that out as just precautionary. We're goin' on the inside here. So basically, it's just multiple compartments here. You got a cooler over there with a couple different evaporators, and you got this one over here. This one here, the thermostat was kinda stuck back behind the boxes, which I'm kinda wondering. So I'm wondering by chance if it wasn't getting the temperature sensing back behind all those boxes of tea there, if that was an issue, you can see where the white thing's at. So I'm thinkin' about strappin' it to the drain line, bring it up, mount it up here, see if that helps out a little bit. Coil is clean. Basically, just kinda gotta check the defrost clock yet, but that's kinda my rationale right now. What we're gonna do is just kinda check some of those things out. So we've got our clock marked right there. We'll see how that goes. I have replaced the contact back in 2017, and it's an R-22 unit. You can see the sight glass is full, not that that would cause this to freeze up, but it's just somethin' I always like to look at. Okay, so here we are doin' the old water down the condenser trick, and what's our sight glass doin'? I think it's basically hatchin' off, not granted it may be just a head pressure control, adjusting it for a while here, see if that clears up. I wouldn't figure that a little bit low on charge would cause it, unless it's not getting the temperature. I suppose it could. It's got 4D cross, so it'll melt the ice off, so it's kinda clean that. You know, it's back to that detective work, you know. What all do we got goin' on here that we know about? We got coil, it's a little bit dirty, not horrible. We got a clock that could be actin' up, we got refrigerant issues, multiple different things. So it's just a matter of work on our way through it and kinda figurein' out which one's the culprit. But I'm seein' there, it looks like it's trackin' time, okay? We got 4D frost for 55 minutes a piece, which is usually more than adequate. It's a timed off defrost. Got that water off of it, and she's kinda comin' back to be in the pool, but still makes me think it's probably low on refrigerant. Gonna go ahead and finish worshiping it out with the fans off. I didn't wanna get a bunch of water in the motors. There ain't nothin' that brings joy to my heart than a water hose that's easily within reach and has good pressure behind it. So, go ahead, got it all washed out, got good clean, clear water, went forward, backwards, take it back out of her at the time here. See what we get goin' on. Remembered correctly, I had looked for a leak last time didn't find anything, it's so tiny. So like we said, you know, they've had this off for a little while, so there's what it is, you know, away from the wall. Let's just say it was buried back in here like it was a little bit ago. Yeah, that's very annoying, sorry. So it definitely brings it up a couple degrees, about three, you're gonna touch more. So, I'm not gonna say that's what's gonna cause it, but possibly be a mix between all these things that combine, recirculating back onto it pretty quickly. Thought about mountain right over there. See what it would be if we went over here. The only thing bad about mountin' on this is it goes right outside and then you have heat potentially comin' through cause it's a short cycle. So about 39 there, may not be all bad. Thing is, it's been like this for a long time, so I doubt that's exactly what it's causein' it. So about 38 there, see what we get on this. Seems like it's fairly accurate to me. So, you could technically put it up here on the ceiling, let it hang down from that. Might be what I end up doin'. You wanna mute something like that, you put a little piece of tape over top of the speaker and it mutes it right down. So that'll make it a little nice, just don't forget to take that thing off. Drop across the coil, which is pretty good. Like I said, you can see the air. Like I said, you can see through the coil pretty easily. Now, everything for the most part seems like it's workin' fairly well. We're gonna head and remounted that bulb up here. Got it so that the stem's at the top so the refrigerant's all at the bottom of the bulb. Hanging it down a little bit so we're a couple inches off of it. Plus you figure the air will move in a pattern so I'm not trying to be completely in there. It's gotta be better than being back behind the cans here. All right, so we went ahead and just replaced the clock cause I couldn't find anything else wrong. It's been, since 13, that it's been replaced and I almost forgot how easy it is to turn these, usually. Right there is kinda, and it finally goes. Compared to this one here where it easily, and it turns right over. So we're gonna go ahead and change the clock. My feeling is it's holding temperature. It wasn't defrosting if the only way you could do it. And I spoke with the other guy that was out here and it's been almost two weeks or better since he was here. So if it was just thermostat, it should have melted it off if the defrost block was working right. So it's gonna be kind of a mixture of a educated guess, unfortunately. I mean, back to blues, blues here, man. Just figuring out what are we missing? What are we not seeing? And then asking the managers many questions as possible, which like I said, she kind of told me exactly how thick it was, which was about a half an inch. And they took them all day for it to melt off. So that's just kind of the most likely thing. And then far as the refrigerant charge, we're gonna look at that. When we come back and do our P.M. in the fall, we can always do it then. So just looking at it just starting out, it's actually flashing right now. I might go ahead and just add some now. Now that it's doing that. May give it a minute. I don't like that the it should be full finally.
