 Alright guys we're heading to an overtime call here. Supposedly the cooler is getting too cold. They claim it's under warranty so let's go take a look and see what's going on even though the equipment was all provided and we just provided the labor. So let's go take a look to see if there's anything that was done wrong or if there's something wrong with the equipment or if it's user error. Alright so we've got some alarms. I've never seen this thing before. I'm not sure if it's the center button. It looks super heat. There's a arm and a pin. That's great. I've never seen that before. That's wonderful. So what exactly is the reason? They said it's freezing things in here which you can see this is a small little cooler. I never seen one this small. They say it's freezing things which got uncovered produce right here. Let's see what they got here. I don't know how this thing even works. Monitor. Okay. So it looks like go back box set point 35 degrees but you can't change it because it's got a code on it I think is what the deal is read only. The foil looks like it's clean. I can't see it here but here's it. It looks like it's fine. Super heat. I don't think I can adjust that. Super heat set for 12 degrees. It's running a 1.5, negative 1.5. That probably ain't good. Oh super heat. No kidding. Defrost settings. Execute. It's air. It's time to number defrost to defrost schedule 2am, 12pm. That sounds about normal. So we're up here on the roof. First thing I notice it's a little odd is we have a defrost clock in here. And that controller downstairs has a defrost system built into it. So I put it in defrost and we're not pumping down. I'm kind of half wondering here do we have it wired for this? It was an option. We unhooked it. I don't know. Been working since November. Kind of half tempted to unhook the contact here and see if it shuts down which would be nice if it wasn't so crammed full of crap in here. That's number 4 brown. Let's see if we can figure out where this goes to. Red or L1 too. There's a 14. That's not even, that ain't even the same colors or numbers they've got there because that's a 70 and a 67. I don't see neither one of those things there. Yeah you can tell nothing's happening because look we got two power wires and a ground going downstairs. That's the only communications we got going on. So there's no no communications up here at all. The pressure switch is probably just a generic little pressure switch which I got right there. It's a little cheap screw on style. So that blue one comes in to here and it does break one of the leads on it. So that's the pressure switch. It shuts it down. So inside it's going to pump it down. This you know it's going to valve it off at the electronic expansion valve and it's going to pump down then shut off. This here I'm not sure why. Well let's look at it. Four goes to four. It's not even hooked up. Yeah that's just a power. So this switch this thing's not even being used at all. So we can ignore that. So everything's going to be downstairs just like I figured. So what I did is I pulled the wire off the contactor very gently not to bump it or anything and it did shut off. So we're going to go ahead and put that back on. I just wanted to make sure that the contactor wasn't sticking. So we've eliminated that. One little trick you can do on that. You can push the contactor in and then put the line on there at the same time on electrician buddies to show me that way before I got in the field. And that keeps you from chatter in the contactor. Of course you know it's not really safe. But just so you know of course we'd never do that in the field. So just want to make sure throw that out there. But I went ahead and just unhooked these wires. Yeah everything's tight. So everything's being controlled from down below. There's really nothing up here at all. One of the other things I wanted to verify here was whether the sight glass was full. They did start it in November. And sometimes you can you know have issues if you don't have it added for winter charge which like I said it's last at all winter and just now having issues with it supposedly freezing. I think we got an issue in our controls. It's set for 35. Superheat's set for 12. I mean everything's pretty above board. Looks like somebody tripped over the line set here and bent this. That's really nice. All right so I entered the code that they showed me on the factory thing. I didn't work. So I entered the one one of the guys told me right now it entered it or trying to enter the cheap mode. I'm hitting the center button. Hitting the once. Try holding it. Try hitting the home button. I think the controls jacked up or the freaking expansion device ain't letting it pump down to what I think is going on. Box temperature 42 in service mode. Force defrost and service slash two. Active alarms. Too few defrost. So let's fix that dense. Snoozy alarm. Sure whatever. Snooze all alarms. Okay let's go in alarm history. Low superheat. June 17th that's not accurate because we're in uh well I guess it is. Today is June 17th. Low superheats happening over and over. Look at that. Look at that. Six o'clock PM. Just going back back back back back back. Lots of that. Okay the differential set for two degrees. Expert pin. Let me go in here. So expert pin don't work. So let's get out of there. So the EXP stepper position is zero of 255. I can hear the refrigerant running so it's not pumping down. You can see possibly no it's not freezing up yet but you can yeah that's can you play with that nope it doesn't do anything. So backup one. General settings. 12 hour. It's fine. United States. Eastern. Daylight savings. Date yep. 1217 yep that's about right. Fahrenheit. PSIG. Basic pin. Ah look at that. Basic pin. Expert pin. We're popping this cover off. I can hear it leaking by. It's not real bad. See if we can uh see if we can see a little better now. There's the suction transducer there. She looks like that's hooked up to there which is right there. It's in her tight fan. Nothing special there on that. I did switch it to 4D frost should not need that. I think our problem is just that the uh this stupid thing is uh not pumping down. You look at that you got box A1 suction temp there. Coil temp. There's supposedly a coil temp sensor somewhere. I wonder where that's at because I'm not seeing it around back. I love learning about this stuff at 7 o'clock at night. It's the best time to learn you know. So you've got your air sensor there but the coil sensor must be. I wonder if they're doing it like some of their other stuff. I wonder if they're throwing it in there in the in the fans and behind the fans somewhere. I bet you not seeing any wires. Yeah yeah I mean if I yeah the coil's cold so that's what's happening. That's leaking refrigerant through. It's getting super flipping cold making this thing sweat like crazy which then makes the dripping going on and that's what's going on. So it's got some issues obviously that stepper motor must be garbage because it's saying like I said that it was at the zero point. So that's your issue. Not much I can do with it tonight guys. Not much I can do at all. All right got thinking about something. If this thing's not paying attention to the suction pressure or if it thinks that that's truly a zero which is not telling me what it is but you can calibrate it here. Let's see if we can read what our actual monitor box temp set point. I wish it would tell me whoosh whoosh I wish I wish I wish it would tell me where that thing is at. There it is suction pressure. It knows it's 71 pounds that's about what I had on my suction gauge so there we go. It's reading that right. Yep that's that's the problem. I wonder if by chance we killed the power if it would maybe run the valve from one way down to the other way. You would think it wouldn't shut the fans off if if it really was or wasn't in a defrost. I just found test mode defrost relay on which just don't have heaters. I thought I could hear that refrigerant cycling through there just shut off you can hear the clicking fan on. It's a neat control I really like it. You could hear that freaking valve doing its jiggity jiggity and liquid solenoid relay on. Yeah it'd be nice had a liquid solenoid this would be working. EXV fully closed. Yep I'm gonna stand by what I said it's getting it's it's it's doing different things but I think it's got to be that valve. Okay so 31 99th little burger it wouldn't come out of that stupid test mode. I tried the star tried the home tried the back I just don't have all the information that might be annoying. So we're back to monitoring mode arms what are we doing on arms serial arms I like that. Reason why it slows super heat because the stupid thing's never shutting off like I said this stupid thing is still leaking through. That dog gone EXV is our problem it says zero and it's not so I'm gonna stick by what I said gotta get a model remember off this thing. All right so I had to get out of the service mode so box temps that point deferentials two degrees preload time zero minutes minimum one minimum off so everything's good to go yeah we're just gonna have to get out of here and call it a day unfortunately so they're just gonna have to deal with it till we get that new one. All right guys it's gonna wrap this one up if you liked it got me some slack my first one I've seen so I've worked on the beacon two and this is pretty much the same thing just a little bit fancier so first one I know what to look for now I know what my passwords are there's a basic and then there's an expert so there's two different ones and let's I know this expert doesn't seem to let you go into the basics so other than that guys you enjoyed the video you want some more like it hit the thumbs button don't forget subscribe we'll catch you on the next one thanks for watching I gotta admit guys this food is really really good these little shell things I mean I'm I've never seen them this small before it's kind of small but they really did a nice presentation with things I've kind of already destroyed everything but this is one of the benefits of being on call and you know you try to do them a good job and uh you hooked up with some good food so so anyhow catch you guys on the next one
