 All right, our next video is one that I recorded back in October of 2019. It's a walk-in freezer that had several problems, which we'll go into detail while we watch the video. And then at the end there, we're gonna go ahead and go back over some of those things. So let's go ahead and take a look at it and see what happens. Got a freezer here that's got some ice issues. It's a little crammed in here. And somebody had the defrost set up for every four hours, 60 frosts every 24 hours. And basically the result is all the ice on the ceiling, ice on the fans, but yet, and for as much as 40-some minutes, our coil's clean. So we don't have any build-up on the inside, so it's a little, it's in a kitchen area. Yeah, defrost is set too long and too many of them. And a termination switch probably doesn't seem like it's working. At the time we're gone, we're at 13 minutes so far. We're 23 minutes into it. Coil is defrosted. Check in here. We've got our limit switch. Looks like it's broken loose. That should be replaced. And the termination switch looks like it's a newer, but whether it's wired up is my question because we're definitely done with the defrost. All right, we just kicked out at 27 minutes. So the termination is working, which is a good thing. You can hear it building up. So the delay does seem to be working. But we really could use some curtains over here. The, since they walk in, they just, the heat pours in. The, they said it got worse here this summer as the humidity got higher. So we're gonna get these cleaned off and reduce the defrost down to four, possibly three. And kind of see what we got from there. Our sight glass is full. Time clock was holding temperature. It was fairly newer. It looks like they changed it back in October 15. All right, this is the condenser unit. We have a nice full sight glass. And the time clock here was set up for literally, the defrost clock here is literally set up for six defrosts for 24 hours. It was set for as much as 50 minutes. So we're gonna drop it down to about 32 and go four times for 24, see how that goes. Go up there and clear off that grill up there and see how it responds. They really need some curtains so it keeps the humidity levels down. Finally got all the ice off of the grills. This took forever. Got all that out. We just used water. We're gonna check super heat and see how, how that is. They don't have any suction ports to tie on to. So luckily this is where the smart probes are going to shine because I can hook this down in the basement to the condenser and I can check the super heat. So that's the next step now. All right, we're making adjustments on the super heat right now. It came in at like high twenties, almost 30 at first. Gave it a little while to stabilize. Ended up opening the valve up. Double checking it even down here at the compressor just to make certain that, you know, I'm not getting any inaccurate readings and stuff. And that's not the case. And then just in case to see whether or not the TXV's got a plug strainer, stuff like that, we went ahead and got our liquid temp and pressures there, exactly the set cooling in. It's only like two. So we're not straining high or anything like that. So everything for the most part is looking really good. Still solid on our sight glass there. Our box is zero. And we're running about 18 pounds suction and about 203 head. And our super heat right now is around nine and a half. It's fluctuating a little bit, just stabilize it down. But between that, maybe add some curtains, all these things combined. I think we had a good place to start along with the long or multiple deep frost back to back to back to back, hanging in there longer than it needs to. The biggest thing I'm doing here is talking to the customer, getting all the history on it and, you know, figuring out is there something that's missed, you know, how long has it been doing this, whatever the case is. And so we're gonna finish this thing out here and make sure that we're on the right track. And then once we're certain of that, we'll wrap it up. All right, so I ended up going back to this customer about a year later to work on a reaching cooler. And while I was there, I ended up asking them, how did the walk-in freezer ended up working for them after I had worked on it? Cause I hadn't heard anything for almost a year and hadn't been back. They told me everything had been working great. They haven't had to have no one else out since that time. So no more ice or anything like that to deal with. They ended up not doing any of the modifications far as doing a curtain on it. So great. I mean, they were able to get away with not having to do those things. So that's wonderful. It appears that the TXV adjustment was one of the big things there along with removing the extra two defrosts. My philosophy was the more defrosts we go into, the more we're bringing the temperature up, the more moisture we're putting into the room. So we wanted to eliminate that and only do as much as what we needed to. The super heat, like I mentioned in the video, was somewhere in the high 20s, mid 20s, something like that. So either the last company just swapped out the TXV and never double checked it or they didn't adjust it when the box was at temperature, which is a mistake that I've made in the past and that's something you definitely don't want to rush until the box is at temperature because it will change as the box drops. I ended up setting that at six degrees to eight degrees area for the super heat and that's generally always worked good for me. It seems to be what I've always read is to be in the area that you're shooting for. Ended up making sure, like I said, there was only four defrosts instead of the six. The termination switch appeared to be working good because we timed it out and it shut off, I think it right at 27 minutes. I set the timer as a backup somewhere around 32, I believe it was, and the refrigerant charge checked out fine, which, you know, that's something you definitely want to check if the TXV has been restricted like this one was with Sahe super heat. Once that super heat starts to drop, it opens up more refrigerants going through the coil. Make sure you're now not low and you're flashing off in your sight glass, which was one of the things I made sure we did. But I was really glad to hear the customer said they weren't having no more problems and that reassured me that what I did was a good practice and everything worked out good in the end. So if you guys enjoyed the video and you want to see more like it, you definitely know what to do by now. Be sure to check out our Facebook page, HVACR Survival, for all the little things that I may not make into a video or the pictures and things like that. So there's a lot of things getting posted here and there and it's a great forum for any of the new guys that want to share information and ask questions without being intimidated. Other than that, guys, thanks for watching. Stay safe out there and we will catch you on the next one.
