Okay, so what I'm seeing so far is that this unit is tempting just a little bit hi, not bad. Okay. Now I need to verify that they're thermometers accurate because mine's saying something different and this one's saying about 39 and a little okay, so I've just got some thermometers in here to see what's accurate. I do see a problem in this coil.

This coil right here has got a fan motor that is spinning slower, so that fan motors not working. This family is kicking ass and there's ice behind that. So we definitely need to get that ice defrosted before we can go any further in the troubleshooting and then over here on this coil. I don't see any ice at this time so we'll see if I got a hose in here I'll go ahead, and you know blow this one through with some water to just to make sure it's nice and clean okay.

So we're gon na go ahead and get that ice on the other, coil defrost it and then we'll go from there. I just want to point something out if you don't know anything about beer coolers, I'm not a beverage technician, but I know enough about a beer. Walk-In, these are some blast fans, okay, their booster fans and what they're doing if you follow the duct or the conduit whatever you want to call it. It's just a plastic conduit, it's going into the tower chase and it's blowing the cold air directly from the evaporator coil into the tower chase.

Now there should be an exit somewhere. You always want to find the exit which would be right here, and you want to make sure you feel air blowing out, and I do I've got air blowing out of this one and air blowing out of this one. So that indicates that both of these booster fans are working correctly. Another problem that I've seen is they've got a little thermometer here.

That tells them they're, you know temperatures, okay and they do use that for temperatures. And if you look at the top, the sensing bowl is going into a little cup and it's supposed to have liquid in it that sound is a hollow cup. So there's no liquid in that guy, so we do need to get some glycol in there. So that way, that's tempting the right are seeing the right temperatures they'll begin their messages on their mirror system.

For that, so we'll make sure we get some glycol in there too. So I'm a water hose person, 1id ice, walking much faster, much more efficient. I don't let the water drip onto the floor ever just go nice and slow. I find it, in my opinion, is faster than a torch, but to each their own.

Okay, we got everything defrosted, cleaned up and now we're back up and running. I'm gon na go upstairs check the charge. I need to check the superheat, but we're Boston on our distributor lines, pretty good, so you make sure these good. It's also nice and warm in here so would just be nothing see how this one's running, who ever hear this oil there's no temperature change on the distributor line the solenoid valve is going to feel like it's running, so we're gon na have to diagnose why this Coil is not doing anything so solenoid coil has 208 volts and it's not energizing so go grab a solenoid magnets it that is the sound you're looking for so want to go, get a solenoid 12 for this guy all right! So I'm up here on the roof.

What I found was that the sight glass is actually flashing, so I'm gon na go ahead and top off the charge right now. It's still pretty warm in the box, so I'm gon na be careful about clearing it too, quick but we're getting there. I have a technician, picking up the solenoid coil for me, I'm bringing it to me so I'm gon na go ahead and get this done and hopefully, by the time he gets here, we'll be ready to put that on right. Now I just have that solenoid magnet down there running it, trying to cool down the space, so this is the first coil and this one's the one running 20 degrees super neat, so we might have something going on with the valve.

I don't know. I went ahead and adjusted the superheat lower, hold the stem down out of the valve to reduce the superheat and then I'm gon na. Let it sit for a few minutes and see if we get any noticeable change. So I'm gon na give this one more adjustment, but I think we got a valve going bad or possibly a cylinder valve going bad, not feeding correctly, because I can't control the superheat on this valve next thing.

We're going to do as I want you guys to see what's going on here and just realize something: okay, that's not just a drain line. That's insulated with a tape, makes sense now and then also and pancreas, which is kinda strange too. It's maintaining some monkeys. Not this whole job is turning into a debacle.

This is our air temperature right now is 33 degrees in the bars. That's what we want to control. Okay, I ended up getting this super heat pretty much dialed in okay, I'm still a little, not happy with the way that valves operating. So I'm wondering if maybe the spring inside is screwed up.

Who knows there's something going on, but obviously we can't forget that that's Illinois valve was doing something funky too, because it burnt the coil out. So it's possible there's something stuck in there who knows okay, so this cloth seems to be working. Okay. They want to maintain about 34 degrees in here, so I'm currently adjusting the temperature, I'm still waiting for the solenoid coil to come.

I have another tech for him. It's me right now. I also had to put seven pounds of gas in this thing too, because the sight glass is flashing, so there's obviously a leak somewhere. So what I'm going to do as soon as I get that a temperature controller dial, then exactly where I want it.

I'm gon na go ahead and shut off the condensing unit and do a leak check on the system and we'll go from there. Basically, I'm gon na get them operating and then I'm getting them a big list of stuff and then we'll submit quotes for everything all right. So you've got a leak on the soft plug underneath the receiver. That's where that seven pounds came from and then we're also picking up a little bit of a leak on these quick connects, so we're gon na go ahead and pull these quick connects out put a proper receiver on there.

If you notice this, we can't pump it down to change the dryer. You have to recover all the gas out of the system, so we'll put a bigger receiver or a better receiver with the valve. So that was definitely interesting. We had a service call on a beer walkin, not working that they were saying it was tamping in the 4243 range their beer was foaming, so I went ahead and found that the right side, evaporator quote, was partially iced up and the right side.

Evaporator fan motor in that coil was spinning slower than the other family shut. The system down D iced, the coil cleaned the coil clean the left side, coil replace the evaporator fan motor then turn the system on and found that the left side evaporator was not running. The it was, it did not have a difference in temperature. Basically, I found that the cylinder oil for the left side - evaporator, was not working properly, went ahead and called one of my technicians got him headed out here to change, to bring me the solenoid coil, because I was about an hour away from a supply house, went Ahead and while I was waiting for him, put my gauges on the unit and found that this system was severely low in refrigerant, so I went ahead and topped it off.

It took about eight pounds of gas got the system running. It was pretty close to temperature and I cleared the sight glass on the system. Then I found that the evaporators I went to check the superheat on both the evaporators and I found that the left-side evaporator was one running about twenty something degrees superheat. While the right side about bird who was running anywhere from eight to ten degrees, it was kind of ranging between the two went to go, make an adjustment on the super heat on the left side coil, and I really didn't get much of an adjustment.

The first adjustment I made - I may have gotten like a degree down to 18 and then I got it down to 16 and then all of a sudden it went down to 1 degrees. So, and I really altogether turn the valve. Maybe one full turn. Maybe a turn and a half like not very much and when I turned it the last time I heard the valve just start, hissing and flooding and who knows what he was doing inside so I backed the superheat off God its to go.

You know a little bit higher, but the lowest I could get it where I would maintain was 16 degrees. I could not get in any lower without dropping it down to 1 degrees, so there's something inside there on the sill enoyed valve. What I did was, I threw a solenoid magnet on it, while I was doing all of that. So that way I could just watch it operate.

I believe that there's something stuck inside that solenoid valve that caused the coil to go bad and I believe that same thing as affecting the expansion valve. Possibly you know there's something going on inside there. Regardless we got the system operational. My guy showed up.

We put the solenoid coil on there, then we looked for a leak and we found that there was a leak on the receiver on the roof on the soft plug and then also there was leak. We were picking up traces of leaks on the quick connects for the refrigeration lines up on the roof. Also, so we're gon na submit a quote to do that. The other really strange thing that I found was that the temperature controller, which looked like it, had been there since day one it's never been changed.

So probably eight years was set at 50 degrees, but it's maintaining 30-something degrees. The sensing bulb for that temperature controller is mounted to the insulation on the drain line, it's just strapped to it, but the drain line has a drain line. Heater come on like think about it, like that's ridiculous, so the heat from the drain line heaters coming up and warming up that temperature controller. I don't know what's going on.

I can't believe someone would do that regardless. You can tell that they purposely set the control that high, because there's a marker mark on it like where to set it, which just blows my mind so anyways we're gon na submit some quotes to replace an expansion valve. We're gon na go ahead and replace the liquid line still annoyed valve on the left side. Coil we're gon na go ahead and replace the temperature controller, we're going to replace the receiver up on the roof of the liquid dryer and then we're gon na diagnose the system further to make sure there's nothing else wrong.

More than likely that's gon na, be it. We leak check the evaporator coil as nothing was popping up, so it looks like we're okay, but it's just blew my mind as to how many problems there could be in one box. It's very important that when you come to do these calls that you don't go in here with blinders on you have to step back before you just start changing parts and really look at the big picture to see. What's going on, don't just go in there di Steve, Aperta Stallone, a fan motor and then walk away because look at all the other stuff that I found you know you really got to stop and think and make sure that we're very thorough when we go to Do the service post that way we can do a better job for the customer, and that way you cover your own ass, because now I can go to the customer and say: hey look.

This is what's wrong. Where do you want me to start? Do you want me to fix everything? Do you want to take a chance just doing something? You know we leave it in their hands, then they make those decisions I'm going to strongly urge them to go ahead and fix everything which they will this customer's good about. That but it just blows my mind, so that's pretty much. It guys have a nice day.
