 This video is brought to you in part by TrueTechTools. Quality tools, essential support. All right guys, so we're on a grocery store here. This is kind of an old one. So what we've got is a freezer. It's not working. As you can see, this thing's a little bit tired as they call it. So this is the one we're actually working on. I can turn it off the breakers and hitting the reset here on the oil switch. I don't know if it's tripped yet or not. So far all I've done is I've came in and have checked to make sure I have voltage contactors. I do have voltage coming out of my defrost block. We have 160-minute section here. I want to see if there's an issue with this oil safety sight glass on here. This thing's just plump, filthy, nasty, dirty. So my thought is I've probably got a screen down here on the bottom that's dirty. Also maybe a screen on the sensor that's dirty. And this is for the freezers. Let's go take a look at that right now. There's our heating systems. Looks like this has got some air handlers with some wires right across the ceiling. Whatever works, I guess. So what we've got here is a total of four little bunkers. These are all on that system. And there's a thermostat controlling all this, I guess, with this one little independent thing right here. Yeah, so all that stuff, all that stuff down, all that stuff down there, all works. This here is completely dead. So I think our main issue, it sounds like when it's running, it's running. It works. There's supposedly a thermostat in here somewhere, which, you know, thermostat or thermometer there definitely is not working. Old husband cases. It's either 404 or 507. I'm not sure which one it is. And it'd be nice to know if that thermostat's in here. We've got wires down in here, but I think it has something to do with the lights. Door seals are not looking the greatest. They are what they are, I guess, right? That ain't our issue here, though. It's a thermostat. I don't even know if it's still hooked up. That's an old writing possibly in there, but that's what we've got. There's no, this is a dual temp case here on this one here. How they're controlling temperature would be nice to know. But at this point, I think we just need to find out why it's shutting off. I think if a thermostat stuff was working before, it should be working still now. All right, let's go back in here and see what's going on. So first thing I'm going to do is I'm going to take this apart. Let's see if we got power to it. As you can see, we have no green light, none, no power to module it. So we have no power to it. So right now it might be a low pressure. The compressor does not seem to be hot. Second and third one up from the mount. So we need a second and third one up. Skip ground. The switch is open. The second one, third one down, tied in with the fourth one down between these two right here. Their port's not opening up or whatever. So even if we hit power here, it's tripping. That's a problem. So we need to make sure that power stays consistent. We've got issues here. We need to check the wiring on this, make sure that's wired right. So we're hearing issues. We're having issues with the pressure. It's saying there's pressure problems. We need to find out what the oil pressure differential is. We're going to check our oil on the suction side. That's going to give us our differential. Usually it's about 45 psi, something like that. So we're on our suction side. We're going to go ahead and open that up. And our suction pressure is, honestly, but it's job. We're not sucking up oil. So either oil levels flow because you can't see it or our screen's plugged up and it's not pulling the oil up into the sump. So we've got an issue here. And it finally tripped out. There we go. So we're going to need to isolate the compressor from the rack or from the refrigerant. So what we're going to do is we're going to pack up on it. We're going to shut the suction, suck the discharge, pull the gas out of the compressor. And then we're going to check that screen. We use that rack to help catch some of that. It's not a good sign. The compressor inside there. We'll now just turn the off, go ahead and hook that back on there that it's actually down to zero. Some of this area around the cover, half piece, part of the filter system in here. I'm hoping maybe I can shove it out in the back. A couple things here. I need to find out the oil safety. I mean, yeah, the oil pressure switch over to the compressor contactor there. I want to make sure this fan whether it runs or not. It took the terminals off the compressor except for one, which won't hurt nothing. Got it wired on there, contactor in one, see if that fan motor turns. So it must not have been wired in right or something. Maybe it was on a high pressure switch. I don't know. It'll be wired on so that whenever the compressor runs, it runs. So we'll probably reuse the oil safety with high and low switch. Bring up a new dual switch for that. Mine there is actually a fake. We'll probably need a little bit of help getting it over here. Use the pie chain to kind of go from there with what we've got right now. Let's see what you need to do. Discover back on. We don't want to lose...
