It's not cooling or freezing right. Let's take a look at it. Coil is just a little bit dirty. It's hard on 404. It's hot there. Liquid doesn't feel very warm, so we're probably low on charge. Somebody peeled this out. I'm not sure what happened here, but the door seals a little jack. Fans are running, which is good. Suction line's cold, but not freezing cold. We got a EPR, CPR valve here. It can kind of see through the coil. We're gonna go ahead and brush that thing off and then let's check the suction pressure and see where we're at. I don't Just don't have a receiver, unfortunately, so it's critically charged. It looks fine. We got a 6 compressor. Then we hook on to the issue we got. Either we've got a defrost issue or we had a refrigerant issue. It's good. Put in a defrost and see what we get. Shit, it looks like we got some 45 minute ones. Let's see what happens here. I don't like that aluminum foil there on that. Looks like a nice place to short. Check to see if the heater elements are working. The hands all look like they're going the right direction. Some of this cleaned up. That's definitely got some issues. The rest of that just kind of foam in there and if we have to we'll rinse it, but once that foam's gone, you'll be able to see through it a lot easier. Let's check down below here and see if this is starting to melt. See whether these heaters are defective or it's just a charge issue. What's going on? It feels like it's melting. Nice. We'll see if I can hold some of that packing. Oh my gosh. Hopefully that makes a difference. Let's see if that makes a difference. That's gonna snap. That's nice. How are you supposed to charge it if you can't get the freaking valve open? Things are freaking junk. I hate these freaking valves. I've tried heating these up before. Yeah, it's gonna break. You don't need it. You may have to drill it and put a tap on it. I got on there with vise grips and vise grips did not work. I clawed the piss out of it, went ahead and loosened the packing nut. That metal shaft whatever is frozen to the other piece of metal down there. So went ahead had to pull the refrigerator charge out. Drilled it, put a quarter inch tap in there, welded it up. I don't have any of those clamp styles that do that big. We scanned it for leaks in the evaporator. Nothing was found. The condenser coil looks a lot better. So we're gonna recharge this back to spec and see how it performs. Coil melted out fine. Boiled off the water. But the product is definitely getting warm so we don't have a lot of times to mess around. I'm not gonna waste a lot of time on it. The condenser coil though. So we're gonna weigh the refrigerant charge back in and see how it acts. If it works good, we know it was low on charge and a dirty coil and then go from there. I had a little hit in the evaporator on the leak, but it kind of went away. It could have been from the steam. I'm not sure. Got to reinstallate this line yet. Nice and easy to get to the 32 ounces that we need. There we go. Give it a second to equalize and let's run it. Got some replacement insulation here for our pipe there. Now it's gonna run pretty low suction thanks to that EPR-CPR. But it's simple. You want evaporator one compressor. I mean in theory it's the evaporator pressure regulator, but it's also the CPR because it's a compressor protector. So you know anyhow, let's go just to regular refrigeration monitoring. We'll watch it for a minute. You could always go ahead and check sub-cooling super heat for giggles. Let's see what we get. So far we've got good sub-cooling super heat. It doesn't seem like it's accurate because that feels a lot colder than 55 degrees. But I don't know. We'll watch it for a bit. Usually they're within a degree or two of each other. Checking it right before it goes into our capillary tube. Now with this being 32 ounces, I mean it's technically critically charged. So it's easier to just do it with a weigh-in method and be done with it, which is why I didn't really worry too much about recovering it and just weigh it back in. Nickel and diamond it in usually seems like it takes much longer. Sub-cooling is looking more respectable there. And super heat, I just that feels a lot colder than 50 degrees. Boxes at 73. This I had to put the probe side by side to see if they were acting stupid and so far it looks like they're pretty much right on. It's still climbing up to about they're usually within a half degree of each other. So it appears that's working like it should. We'll keep on checking our super heat here. Boxes 66. Pricer's dropping so I'll let it check and see if the fan's running. No, actually they are running now. So suction pressure should come up now. Yep, my message just came on when I was in there. Suction's starting to come up. That's a good thing. It's up there a little bit. You could only imagine what it would have been at when it was completely plugged off like it was. Spatia being the shroud around the fans is non-existent. Couldn't maybe put a piece of cardboard across the top. It would have maybe helped it out a little bit. Just putting that cardboard across there. I got it right there. Took it from 280. It's already dropping. That's quite a bit of air difference there. So we're going to wire tie that thing into place. That'll help lower the head which then it'll help lower our evaporator. It's going to be a combination of multiple different things here that's going to lead to a better working unit for sure. It's nothing more than a box of steak or something I cut into a strip and unfolded the box. So make and do with what you got. I got it scrapped there on the sides and the center. And also as you can see this coil, I didn't scrub that at all. Just what I used that brush just to get the outer cover off and it did a heck of a job. I've been really happy with that biker stuff. It's not always perfect, but it's done some really good work. Went into the defrost clock here. It had it 45 minutes, almost all of them. They don't have a termination hooked up which kind of sucks, but it's been like this for how long. So we're going to just do two of them 45 and two of them a half an hour. The half an hour ones are going to be during their normal times where they're going to be in here working. That way they don't think there's something wrong with it. So that's there at that. Just need to go back and see what our pressures are looking at. Otherwise we're already at 29 degrees. Things are looking good. We're going to need to order a door seal for this thing. If it's any good, the track. Drop that head pressure almost nine pounds. She's pretty good. Got eight degrees sub-cooling. And we've got 33 degrees super heat which is pretty good. Normally they want at least 20. So that's looking pretty good. Boxes at 18 degrees. Very so slowly dropping because the product, you know, warm. Pressures look pretty good. Head pressures came down to 260, suction is still 17, 21 degrees super heat, which is why you don't want to go too crazy when it's under a heavy load. It'll drop as it gets closer to box temperature. And sub-cooling is still respectable at around seven and a half. So guys, this is going to wrap it up. I've recommended that they replace the evaporator that goes low right away anytime soon. However, the box is in poor condition and that the middle door needs at a minimum a replaced door seal. Leave it in their bullpark what they want to do next. But for right now the system's working and they'll be able to get through the weekend and move on with their day. So easy sleazy and easy to pleasey. So I am out of here guys.
