 This video is brought to you in part by TrueTech Tools quality tools essential support Walking cooler. It's not working. Let's go see what we got going on. Is this the cooler that's not working right? Well, you can see how bad the other one looks this one here I can hear it running, but we have no fans It's cleaner than the other one. I've been through it a hundred mile an hour. These are those bone miser TXVs that I had to deal with not too long ago. That didn't make sense. I don't know if this was originally a freezer. Maybe that's why the fans are not running. It's getting power from up on the roof trying to maneuver around all this stuff in the way. Hey it's NorCal Dave's beer of the day. Now this is a beer cooler as you can tell it's a beer cooler which means we usually run a freezer style unit in here and means it'll have heated defrost which really makes it easy to get to. So let's get in here and see if by chance it's probably not getting cold enough. That's probably what's going on. And the temperature switch is not hitting to bring the fans on. Bar of the fan delay. Let's see if we can get up here. Do we have a fan delay on this thing? All right so here's your defrost termination switch right there. So it's going to have one. Okay I did not see a defrost termination switch on the other side but there's that big bone miser honker donker there medium temp TXV which like I said is not running very cold. I remember this being a little low. Wouldn't be surprised if that's not leaking because believe it or not that little bulb right there is literally in the suction line and is can leak around that thing because it's just got a rubber seal around it that's squeezed just like a side glass on a boiler would be. All right so I did not look very closely. There is a fan time delay termination switch right there. So your power comes in on four. In is always the other side of power so if you was to go to in which is right here and go to four you should have power which we've got on four. Okay let's see if I can make this easy enough. You have power coming in on in into the switch and out of it coming back over to f1. The other side of f2 goes to four. So four has one side of power and the other power comes out of the black lead. So if we use the jump black which is in to f1 it should run which we already checked it with the meter. So I'll go to f1 which is right here and go to in which is right there. Look at that. There's your fans. So yeah our problem is the switch is not cold enough and that's why it's not wanting to run. So that also explains why the TXVs are so noisy because we're low on refrigerant just about guarantee it. So let's just go outside and do that real quick because we'll probably have to look for a leak in here. All right what we're going to do is grab the leak detector. Miles is going in there and check for leaks before we get the fan running. That way it isn't blowing the stuff all over the place. So we're going to get out the world's greatest leak detector. So we got the old TX Stratus warming up. All right so warmed up ahead of time. They've got so many things in this building that leaks it wouldn't be a real surprise. Okay let's just go ahead and get up in here for all those elbow joints are. Go over here on this other side where the TXV is checking around the suction on the TXV. We already scanned all this. Stuck it in to the fan area there which you can't do with an H10. And getting those nice tight spots. So I've got nothing not granted it's running so the suction pressure is going to be in the 40s probably depending on what refrigerant we got. Let's go outside and get this thing charged up and get it running. Okay obviously that's right there coming out of the very back one. So it's going to be this first one. I think the one I worked on the last time was one back here at the back. So we're going to go ahead and focus on this one right here. Let's get it opened up so we can see what we're doing. Yeah I remember there being a lot of oil in here and not knowing where it came from and not sure if it was like from another compressor change or something. But that's an 05 compressor so this thing's been in at least 17 years, 18 years. So it's just like a brand new spring chicken. Let's go to our front sight glass here. I think we're going to see what's obvious. They put the disconnect box down there where it's real convenient. Let's scan it over real quick if we need to make a fix. We can do it before we have to pull it back out. Worst case scenario with it being that's 220. We could always come back or whatever. See if that one controls the back when that would be logical. Yep it looks like that's the one. It's slowing down. Lucky here nailed it in a couple seconds. Right there. Never fails on a discharge valve. They always leak. I would explain why there's been crap everywhere all over. Go ahead and scan the rest of it. But I've had that leak multiple times. It never gets tightened up usually at install and they get left loose from the factory. I'll like scan on the backside of the condenser coil. Usually cleaner and it's got that shroud around it to help keep the wind out which helps out. But right there seems to be the main one. Let's grab some soapy joke. Get some solid stream on there if possible. Let's see if it's leaking on the threads. Hopefully that way we can just tighten it up and not have to cut it out. Now we should be able to tighten that up and not have to deal with it. Listen that up and then look at how bad that's leaking. Yeah somebody's toasted that. Oh wow it's going nuts up here. That's gay girl. She's going nuts. Look at that. It's leaking out of the bottom even. Oh yeah look at that. Look at that. Look at them cookies. Chocolate milk and cookies for everybody. Heck yes. Goob that full of freaking pipe dope or something you know. Or chop it out. I'd prefer not to have to chop it out. Let's grab some nylog. Goop in it. Maybe get the wire brush out here. Let's see if we can get away with not having to go berserker. You can see some like rust color. Yeah she's going nuts. She don't like that. Probably not the right cap. Yeah cleaned up that side. Somebody probably cranked down on way too tight. It has a little red raised edge that generally just needs slightly tighten like a eighth of a turn and usually it'll be fine but unfortunately somebody donkey conged it and got her done. Let's grab a little bit of my favorite nylog. It gets a little messy. I think that's silly. It's messy. I don't want to get messy. I don't want to get messy. Get a little stuff on my hands. Put a little bit in here on the threads. That part there. She's she's she dizzles and diggles. Put that right like that. See if I did it. Not seeing anything. Now granted it's not running either with 250 plus pounds of pressure on it. I think I would feel a little better if we added a little bit of teflon tape to it maybe. Get in there. Wrap it the right direction. I hate getting rid of it because you can actually isolate the compressor if you need to. And I prefer not to. Plus time factor. I got to go to another one of their locations and fix another one. Okay not leaking. Okay we'll leave a note up here. Discharge valve leaks. I'll do 413. There we go. Left them a little note. That's sealed. I'm not picking up the detector or that. We'll do it when it's running with high pressure on it but it's no different than a screw in pressure relief valve for a liquid receiver tank. We usually use pipe dope of some sort. Usually like a lock tight brand white stuff. I forget the 700 number whatever it works. Either way let's go grab some go-go juice. This should be 404. Let's see that's PoE so it's going to be 404. And get this thing. Draw up an attempt. I'm sure I've said things about this before. That wireless scale which is really sweet just like all the Testo stuff. Do it right here on the display. Don't have to get out your phone if you don't want to. It has that option but you don't need to. Then again refrigerant charge. I'm going to go manual. I do have the auto capabilities on the solenoid which is out in the carrying case for this but I just don't use it very often. But if you're doing a bunch of startups things like that it definitely would be useful for that if you wanted to walk away and try to be as productive as possible. Let's go ahead and kiss back on. I already rotated my clocks so that we aren't going back into a defrost anytime soon. And it just so happened to be perfectly at the three o'clock mark. All right luckily we're at 34 pound suction so that means we didn't pull anything in. The pressure switch would have shut it down so we don't have to miss with anything far as dryers or anything like that. Go ahead and get this thing added to it. The compressor doesn't sound the greatest in the world. It's not the greatest in the world that's for sure. It's like you know everything looks fairly okay. You'll spray that thing see if it's bubbling. The detector's not going to be real great at that wind blowing like a I don't care what detector you got on that. And we do have a accumulator here on the suction side of the compressor. So we're not going to be slamming it with liquid too bad. I mean obviously we got to charge a liquid and we're kind of moving along fairly quickly. But most part that nylon is going to fit in between the brass cap and the brass threads there at the top and it's going to seal when it squeezes down on it. It like I said we could chop it out and then you have to change the filter dryer, pull a vacuum, a lot of extra time. As you can tell generally they don't want to spend any more on they need to on it. They just want to keep the toss down and keep moving along. And baby she's coming. That'll fluctuate a little bit more. We're right there at 4.6 pounds. Pressure's dropping a little bit. She'll settle down. Probably could use a wash enough for sure. You can see the TXV starting to pull back a little bit. I've not dumped any in for probably about two three minutes so that frost back is slowly disappearing from the TXV adjusting. Run about eight degrees, 244 head. So as soon as that starts to slow down a little bit that'll also fill up our side glass. That'll back it up a little bit. Not seeing anything leaking on it. I know that's not the greatest way of doing it but if you know your customer you know what they would rather have and I know they would rather have cheaper if it works. Looks don't matter, operation does. There's other ones where absolutely take your time, chop it out. It just really depends on the customer. Went around sprayed all of our other little fittings here just now that we've got more pressure build up on it. All our fittings out here, everything looks good. Cilenoid valve's good. 267 on the head. She's rising a little bit. Let me take a look here in this coil. This looks a little jackereed. Actually ain't too bad. Okay well we're running that head pressure there of about 265 area. It's a little warmer today. I think we're going to get up to 80 which is really surprising for mid-April for us. I'm not picking up any speed ups or anything so I think we're good on that. Looking good. Not flooding back no more. Not bad. All right let's go back in here and make sure that it's dropping in temperature and the fans are on. Yeah just like that right there needs needs cleaned up. Fans are on. Looks a little better. Yeah working good. Not too horribly dirty. It's a little bit of gunk on it. Now we're near what the other one is. Let's check the thermostat. See where it's at. About 32-ish. 32-ish. They do got some glass stuff and water in here you don't get too stupid with it. This is where all the kigs are and stuff are at so they're going to run at the colder. They have it all on tap and it all goes to the front. Plus they got meat and stuff in here too so yep and look at that right there's the thermometer running about 38-36. All right guys it's going to wrap this one up. I did check with them about washing out the coil. They usually do their own maintenance on their coils and their HVAC stuff. We usually just take care of the refrigeration and if they can't get the other stuff working then they call us for that so simple stuff like maintenance things they have in their own maintenance department for that. I forgot about that so they're going to do that here in the next month or so washing out coils and things. Like I said no reason why the fans didn't come on it's because the defrost termination switch that's used typically in a freezer is what they're using in this cooler because they do run at colder temperatures that's why it has defrost heaters on it because they want to run it just at or below 30. That's the reason why we run that type of evaporator with the cooler is just so we can run those lower temperatures. Everything else looked pretty good for the age of it. Like I said it's 2005 and I'm sure we'll be back for plenty of other things that we work on. Guys I appreciate you taking the time to watch the video if you would consider subscribing.
