Today, we've got a keg, kooler fear walking about 48 degrees. Let's take a look at the backside. I've got a very deteriorated. Coil very old looks like the serial number since 1993.

Definitely gotten life out of this thing, so basically we got to start on the roof. The temperature controllers calling oh this - is my walking right here. It says beer walk-in, that's the culprit. Condenser fan motors not running so we're gon na get in there and see what we can find.

Yes, because there's part of them very rich family, let's bamberger's locked up, find the breaker for our car. Luckily, there's a big fat part number right there. Local supplier has it in stock. I'm gon na go ahead and go pick.

One up, fan, blades and decent shapes. I don't see a problem with that motors hotter than dirt and it was locked up so we're definitely going to talk to the customer about some potential equipment replacements, because this is an old r22 system. The original condensing unit original evaporator the compressors, been replaced once before, but that's about it and the compressor looks like it was replaced in 2004 from the serial number on top. So we're gon na try to change this again.

It's kind of one of those things where this thing is so hot we're gon na be lucky. If we don't have bad discharge valves, but there's not a whole lot. I can do right now, because we have such high pressure and the compressor is so hot. I don't even want to run it so we're just gon na go ahead and go pick up a condenser fan motor and then, when I get back before, I put the motor in I'll put my gauges on it and see.

I guess you know I'll. Just put my gauges on it: real, quick, it's not gon na tell me a whole lot cuz. I don't want to run it any longer. I just don't want to.

Potentially I mean I know that we're gon na have compressor damaged, but if we can get by until we can replace this equipment, that's what I want to try to do so going against everything. I just said. I turned it on and we do have pressure differential. So the valves are somewhat still there.

I don't doubt that we've damaged it, though, but I'm gon na go ahead and try to replace the fan motors. If I don't get us by until we can do an equipment replacement. So we got the fan motor changed out. Pressures have pretty much equalized out in the system.

The R is my box temp, I'm using the field piece, JobLink ropes with the new manifold. That's my outdoor air temp 72 degrees. What's interesting is while I'm up here. I could hear that this fan learners got to they'll, have to change that, and this one I might be hearing a noise from this.

I don't know - or it might just be off on fan cycle, so I've got my amp clamp on there. We're gon na go ahead and fire this guy up. We're allowed to run one amp, let it run for a little bit we'll see if we can get this thing to operate. I already know we're going to change we're gon na talk to them about changing this equipment, but I'm trying to get it working, so I don't have to change a condenser and evaporator today, so we're gon na.

Let it run for that shut everything else off. So I can hear myself think we're under amps the unit's allowed to run 1.0 amps and we're at 0.77. It's going in the right direction. We've got a cold suction line.

Current pressures are coming down in temperature, we're gon na watch the Box drop in Tim. Like I said, I've got my psychrometer hooked up downstairs, so this R right here is my return air temp. So I can already it's going to be hard for me to show you guys this. This has one of these old-school player sight, glasses and they Venus flashing, so we're gon na.

Let it operate for a few minutes and then, if it's no flashing will top off the charge also, so we are pretty much down to temp inside the box 38 degrees and what we're going to do is a pump down test. I've got the low pressure neutral bypass, but I put a screwdriver under the bellows. We've got the suction service valve right here we're going to loosen the packing. I always want to loosen the packing before you do, those on a receiver or any other kind of out, and we are going to completely front-seat the valve.

We are going to watch our pressures on these older compressors. You cannot do this on the scroll, but on these older compressors we should pull down to negative 15 no problem and we're struggling. It should have already been down by now pretty confident. Well, I know we have a suction valve in here.

That's that because earlier I couldn't capture it on camera, but I could hear the compressor bypassing internally when we have high pressure okay, so it should have already pulled down by now. I know that much so what we're gon na do it's actually not even low enough. We're just gon na shut it off. Okay, and the pressure should not rise that fast, it's okay to rise slowly, but not that fast, the the suction valve inside whether it be the read on it or what is internally leaking and it's weak.

I have a feeling we have a bad discharge valve too there's like a little well. You guys know how compressor works. Oh so it's internally bypassing so we're going to come down in ten and it's going to be okay temporarily, but we are going to talk to them about equipment replacement. So I'm going to go ahead and back seat.

This valve all the way back out and then just crack it so that we have pressure on the valve. Okay, now it's cracked and then we got to make sure we close that packing back down, because these things Julie doesn't got to be like super tight. Just snug okay, so our box is down to temp, but we've got a weak suction valve. This will get the customer by we're still flashing on the site glass hard for you guys to see.

I'm gon na go ahead and clear that up and then we're going to go ahead and quote some new equipment for these guys and that compressor doesn't sound, very healthy either. Definitely got some stress going on, but it'll get them bye for now. So, like I already said at the same time, I heard this one, the condenser fan motor sounded really bad, so I wouldn't picked up a condenser fan motor for this, so I'm gon na replace this. You know I've mentioned this before, but I'm not a fan of using headphones when you're working.

I really don't think you should, because you miss out on other stuff, but it can also be a safety issue. So while I was working on this, I could hear the compressor up top. You know I could hear a problem with it, just because I'm used to the sounds and what it was was. It was running really hard because the convention fan motor had failed.

So you know that's one of those things where, in my opinion, you really shouldn't be using headphones when you're working, because you should always be able to listen to everything around you. You still got ta use your senses all right. So at this point the customer had approved the equipment replacement, so we had ordered all the equipment and I had it sitting in my shop and then I got another emergency service call on the equipment and you're gon na see right now. So this kind of seems like a bad dream.

This is a Saturday night over honey share. This call: we've got a bad connection, fan murder. We can do compressors red-hot, okay, it's gon na be some Frankenstein stuff right now so because this equipment was already spec for replacement, I happen to have it in the shop. I don't really want to change the whole condensing unit tonight, if I don't have to so.

I'm gon na try to steal the shroud and motor off it here and make it work temporary we're just going to disconnect it. It kind of matches up height wise. It matches perfect width wise, it's a little shallow, but I think I can make it work. So we're going to take off this whole shroud and you'll see the fit on there.

So so what I did was temporarily put on the shroud from the new condensing unit under that guy make sure it's not over amping I'm gon na watch. Psych glass is clear enough: the old-school Cyclops we let it run for a little while here's the old motor and I had just changed that motor recently too. So there's something going on. You know I'm going to check to make sure we're getting a proper 208 volts to that motor, but so we're in it's running still coming down to town, so we're looking good so far looks like our compressors.

Okay, like I said I know it, has a week valve weak suction valve, but this will get us by new condenser fan motor. For now - and I checked the condenser fan motor voltage, it's 207, so I'll come back out and change this convinced you know we're gon na change, the evaporator coil too, so alright. So this was some really old equipment. We had a service calling the beer walk, and you obviously saw that we had the original call where I had a bad condenser fan motor and then diagnose the system to have a weak compressor, convinced the customer or submitted a quote to the customer to button change Out the equipment and upgrade it and they approved it, and then I got that emergency service call before I could get back out to replace it and found that the condenser fan motor that I just replaced had already gone bad again.

So obviously something was going on there so because I already had the equipment ordered. I took the entire condensing unit out to the job. With me thinking I was gon na. I was thinking the worst that that compressor finally took a dump or what, but it was just kind of a trip.

I had the idea of taking off that fan, shroud and temporarily putting it on now. Once I put that fan shroud on, you know, was up and running and and got it going again, so we'll have the replacement video coming here soon, where you guys will see what we did, but that fan shroud got me by until I could get back out And replace all the equipment. I really appreciate you guys taking the time to watch these videos and it's pretty much it on this one. I will catch you guys on the next one: okay,.
