This video is brought to you by Sportlin. Quality, integrity and tradition. I've got a call. It's uh, late in the evening and what the heck is going on here? I'm gonna call it a walk-in freezer.

not working, but you hear that sound and the temperature controller I Don't know if you guys will be able to see it, but it's like glitching. That's odd. Yeah, something's going on with that temp control. Okay, well.

let's jump up onto the roof first and see if we see anything going on up there. That's weird. It's like glitching. All right.

This is my compressor. Condenser looks clean I can see through it. It's warm, but it doesn't feel like it's off on overload. It just feels like it's hot from the day.

Let's open up the electrical section over here and have a look at what's going on in there. All right? So if we go from N to four, that should be full power to the evaporator coil which should be powering my temperature controller which should be turning on. So the fact that I'm not seeing the power at Foreign N on this defrost clock flickering or doing anything funny like we were seeing at the temperature controller makes me think that we might have a bad temp control. So we're going to need to head downstairs.

I'm not going to turn off power yet. we're going to head downstairs and we're going to open up that temp control and see what's going on within the actual control. Oh, that's not good. Look at that as I'm taking this thing's gonna blow up in my face as I'm taking it out.

Water is dripping out of it I Know this restaurant is notorious for having roof leaks I bet you anything we just had a tropical storm go through and they got hammered with rain out here. if that's you anything. The whole top of this box was full of water. Okay, oh no, it's not too bad.

Yeah, but there's definitely water in there you can see all right. So power that looks like crap. Um, power is the top two on the right there. and if we have 208 volts proper which I think we do, it's a bad control.

208 volts. We don't have a display a proper display on the control 26 206. so hopefully I got a control in my van I think I do so I don't have the exact control but I have a control. but look at the FlyAway wires.

the wires that are just pushed up. That's not okay. Luckily it didn't cause a problem. but yeah, you got to make sure your wires are really getting terminated properly.

So I installed the ke2 because I didn't have uh, another one. Now this one has built-in defrost but we're not going to use it so we're just going to hold this down. I'm gonna go in here. We're gonna set it for negative 10.

I Had to set it up for 208 volts so we're just using it as a digital control. Basically if I go negative five because I don't think they need negative 10 necessarily I don't know. They do have ice cream in here actually. Yeah, I'm gonna go to negative 10.

I wonder if I did something wrong because it didn't turn the coil on? Hold on. Let's keep going through this. We're gonna change the defrost time to zero defrost per day I'm Gonna Change it to zero compressor starts per hour. It's just that off differential.

We're going to change it to three and that's it. So I must have done something wrong because should have turned on by now. Should have opened the solenoid. Let me look into this.

Wow, what a mess! Okay so I got in here I don't think I had anything miswired. So let's let this guy turn on. see what it does? Is that 47 right now? So let's give it a few minutes, hear it click on and see if it turns the solenoid valve on. I must have had something messed up because now it turned on.

So I just ended up yanking everything apart and then double checking on my wiring. So I must add something crossed or something. All right. Well, I got to put this all back together and then hopefully we'll watch this guy come down to 10.

all the evaporative fan motors came on so we know that the defrost termination switch is working, so that's good now. I need to get the solenoid cover back on I'm gonna have to turn off power to do that because I got to shove a bunch of crap in there guys. I think it's in a time delay right now because it was running a minute ago, but I had to shut it off. There we go.

So I had put a time delay on here the last time I changed this compressor because I was sick of the short cycling. Um, so it's running now. we're gonna let it run. but I noticed that this defrost timer had the wrong time and it's really hard to turn.

So I'm actually going to swap it out real quick. I've got a new one right here so we're gonna do that and then we'll put it all back in operation. so if it doesn't blow up. Nope, didn't blow up all right.

Oh man, now we got stuck in the time delay. Okay, so we are set. It is currently 908 p.m about right there. These guys are kind of silly.

So we are gonna set a few defrosts here because they really really ice this box up often. So I'm gonna put a little. We're gonna start with four defrosts for a half an hour and then I'll add in a couple more in the middle of the night. All right I set it up.

So I got four. Defrost One One seven, Seven ish somewhere in there. Eight ish, whatever. And then I put a a half hour at four, A.m and then a couple 15 minutes throughout the day.

So now I'm gonna pop over here. We're gonna watch the system operate all right. It is currently 96 degrees outside. We have a clear sight glass.

We've got a nice big Sporland C all there. This is one. I don't know if you guys remember, but I did a compressor change out on it. Was a pain in the butt.

But all right. Um, we are looking pretty darn good. I can actually turn this off. it'll make it a little more visible.

So 404a 115 saturation. That's not too bad. um 28 degree I'm sorry 28 PSI Negative 4 on the EVAP I'm not really seeing any issues. I'm going to take my gauges off, leave this running, put the grate on, and head downstairs and see if the box is coming down in 10.

All right, and we are running. It's about 21 degrees inside. The Box evaporative fan motors are moving, air coil looks clear. I'm not going to stand around and watch this I Got an hour and a half two hour drive home so this is all they're getting for today.

Um I'll call and follow up with them tomorrow. uh on the phone. This one was a bit frustrating and let me preface this: I don't like asking management about details right? Uh, and what I mean by details? It'll make sense. Like when this manager called me, he called me on the phone and uh or actually I called him when the service call came in.

We got an email through their invoicing program and it said hey, emergency service call walk-in freezer not working so I called them and I said hey, what's going on walking freezers down he goes yeah he goes I already checked the breakers, the fans aren't running and I go okay, that sounds like an emergency man, it was probably I don't know nine o'clock at night or something like that. So I was like all right, well I'll drive out there you know and actually I think it was like seven o'clock at night when he called me, but it took me two hours to get out there. So I got out there like at nine but when I was on the phone with him though before I got off the phone, you know he said yeah, it's not working I said okay I'll head out there no problem and he goes yeah he goes I noticed it this morning at 9 30 in the morning. he goes but you know the fans weren't running I figured I'd just shut the door and see what happened and he goes.

Now it's you know, seven o'clock at night and I'm like dude, why did you tell me that he's like, what do you mean and I go Why did you tell me that you noticed it at 9 30 and then now you need me to drive all the way out there, you know to fix it I Said it's better if you just leave that part out, just tell me it's broken I don't need to know when it broke Okay I don't ask those questions anymore. He's like I'm so sorry and I'm like that's fine But I said now we're on overtime I said You: You: You're concerned about money. You know you're trying to save money, so you want to shut the door and see what happens. but then you forget about it and you call me late at night when now it's overtime and they have to pay me a lot of money to drive out there and to drive all the way home because we charge travel time on overtime home.

So it's like you know, it took me two hours to drive out there I was on site for three or something like that and then they paid me two hours to drive home. you know? So anyways, regardless, I got there, found that the unit had a bad temperature controller, went through the steps, and then while I was again because it's about the big picture, right? I don't just stop there, put my gauges on it, check it out, see it come down significantly in temp. Also found that the Defrost clock wasn't really turning very well. Went ahead and changed that too and they're fine.

Everything's back in operation now. I Didn't stay and watch it come down to Temp because it had been down since like 9, 30 in the morning it was like like 40 something 50 degrees in the Box it was going to take forever to come down to 10. you know. So I just watched it come down significantly to in the 20s and then that was it.

Got out of there. Um, it's been I don't know five days since I was on that call or something. So all is well. everything was working.

Um, now you know as far as me taking a shortcut and saying hey, I'm not going to watch this entire Box come down to Temp If I wasn't in charge then I would want to call my boss and say hey, it seems to be working great. What would you like us to do you know I never leave that up to management I don't put that in their hands I Just you know I make those decisions and so it was no big deal for me. I Felt confident looking at the vital signs of the system. We had a Clear Sight glass didn't see any issues.

compressor condenser was clean like everything was cool. the ice pattern, the frosting of the TXV everything looked fine. Okay so I just don't want you guys to think that like I just half-assed everything. No I'm looking at Vital Signs I'm using my experience I'm listening to things, looking at the operation and making judgment calls based on what I'm seeing.

Okay, um, we don't always get easy ones like this, but sometimes the easy ones like this can be frustrating because it can be in the middle of the night I bite my tongue I did tell the manager like, hey man, don't tell me that kind of stuff you know, like just keep that to yourself. just let me do this. you know I did say that um but other than that I didn't give him attitude I didn't have a problem when I was out there I wasn't a jerk to anybody. It is what it is.

It's broken regardless and you know it needs to be fixed. So that's what I'm there to do I really appreciate you making it to the end of the video. Thank you so very much for watching.
