 walk-in cooler that is not cooling. I wanted to verify evaporators are running. I've already taken a look outside and it's not running. Just doing a quick visual here you can see that the coils pack pull a garbage. Nothing's running. Let's pop her open and take a peek in there. Okay it's got power. Nothing's running. Is it because our thermal is open? Both fans are running so we know that that's uh not an issue and she just went down into a pump down. At least it seemed like it. Magnet kicking on so we know that's uh calling. So I'm going to check the pressure switch or it could be the thermal. She is closed. Left is your safety switch. So we have a high pressure switch. We have a low pressure switch. Let's go ahead and get that back cleaned off for right now. This freezer is looking over here. It just is bad so we're going to get that cleaned out. This ain't the greatest thing in the world but it does serve its purpose. It will clean this coil right off. I brushed off all the garbage on it first. It's just letting back. Great and our temperature should be starting to drop. I'm at about 35 degrees saturation. I wanted to make sure to check the freezer while I was here. Some of our fans ain't running. So this is another reason why you don't just do what you're there for. You kind of look around and make sure there's nothing else going wrong. The motor acts like it wants to take off. The capacitor or the run windings are out on it. Here's our headmaster which we just still bubbling. Got the capacitor out. Check to make sure voltage is down and our capacitor is at 3.8 microhertz. So obviously the capacitor is good. It's rated for 4. The start windings have gone out and that's where we're going to have to replace that. This motor has reversible leads which is kind of nice. It's a 96-56, 230 volt and then we've got a 120 volt version also. Today's date on there so we can keep track when it was replaced because you know the old saying you were just out here the other day. Sometimes is last year or two years from now. Rated for 0.48 and we're 0.47 so we're right at our full load amps. We're not over. You always want to check your head pressure if you're going to adjust charge. I've made the mistake of not doing it before. Run in 404 type of system. There we go. Let's turn on our probes. Activate home. 31 pound suction. Got some bubbles again. Superheat 63. That kind of sucks. All right. Add a little more juice. This one is aluminum microfin coils. Got to make sure to calm down our solenoids outside here. We tend to do that a lot on our systems if they're not real long with runs. With that frosting back like I had, I didn't see for heat was up there around eight or nine. There's still some bubbles. So the TXVs are adjusting because we've not been given it a full solid solid liquid. So they're going to set to an adjust and open and close like peekaboo. Okay, we're going to put this back into the defrost again so we can look for a leak. We'll do a leak search out here. The main suction first also tells us whether or not it can pump down on its own whether it's going to have any problems. We're going to do this first. It's going to pump up our head pressure and then it shuts down. We'll search all that and then we'll release it and then we'll kill it. That way it's got some refrigerant in the suction side because right now it don't have anything in the suction. We're very little but it does pump up our high side here. They were calibrated a little hot but hey, I'd rather find it than not. All right, she's already starting to let me know that there's something up there. So it looks like we're slightly froze up on the left hand side. I'm going to need to run her through a little bit longer defrost and find out what's leaking up there. But she found the leak without even having to get up to it. There's the oil. You can see it there on that black piece of armaflex there. You can see the oil down in the pan. So we've got to melt this ice out of here. Just slowly melting this ice out of here. Believe it or not this actually works rather well. Just a generic little pump sprayer. So all you got to do is melt it. Otherwise it'd be here forever. And since we got that we're gonna get this over here. Okay we've got all the ice melted out. We're not getting anything in this area here. Make certain it's not falling down from up above. I'm not getting anything. Now we're just gonna spray them more time then I'm gonna brace that over and be done. This is the infrared. I don't usually like it as well. But I can't get it to bubble but yet she goes off no problem. We can do medium here. See how medium does. Medium does not get it. Just high. Now I'm gonna go ahead and pump it down. Re-braise that. All right we just went over top of the braze joint that was there. Took the bulb off of the TXV. Don't want to fry it. Soon as I hit it with a torch you could see a crack across there. So I don't know if he moved it or for some torque on it or what exactly happened. But as soon as it did that I could see it. I went ahead and filled it in and everything's happy to go lucky now. I got everything back together. Getting ready to run it. Got that all taped back up and wire tied back up plans and go ahead and get her going. Now what's kind of interesting as I'm looking at that headmaster there. It's set for 180. This is a brand new unit. And one yesterday we did was 180 but yet the paperwork showed 404 should be running about 210 which would be more in the 90 degree liquid area. So we uh something I also do too in case you forget that you got that unhooked. I always put a piece of metal in there. That's just happened to be an extension. That will keep you from burning your coil up. Otherwise you screw up and forget. You wipe your coil out. All right I can hear the refrigerant pumping through. Fan delay. Termination switch needs to make yet. As soon as it does fans will kick on. So we at least know that much is working. Things are actually working. Let's say looking good. All right guys that wraps this one up here. Fixed the leak. Worshed the coil out. Got everything going good and replaced the condenser fan motor. We weren't even here for this. This is the walking freezer. The walking cooler. That was the initial call for being out here. It just wasn't running because it was off on thermal overload. And once again that was also because the condenser coil was packed full. And then same thing. We went ahead and got the coil cleaned on the ice machine. Remote condenser there.
