 This video is brought to you in part by TrueTech Tools quality tools essential support All right guys, we are on a walk-in freezer. It's not working, right? Just got here never been to this place before So we got a beacon system. They're getting some codes on it. So we're gonna figure out what's going on here E3 and See if we can figure out where that code things at if not I've got one out in my truck That's what we got going on starters coil Is clean which is good so we're not a freeze-up. I think we got a sensor bad, but let's figure it out here All right, I got two different books here These things are kind of old but they're for the 79 a and I think 80 a or something. So E3 is a suction temp sensor This is check sensor and word connection. So let's check the resistance see where we're at problem Is that suction temperature sensor? If they don't have the suction temperature sensor can't do super heat and since it's an electronic expansion valve It doesn't want to flood the coil. So you can see the suction sensor comes right there on the suction line Comes up and buck connected to there and there's the suction temp right on the board So we can also go in there and could read temperature that it's reading and see what it's doing Just by scrolling around through there Monitor probably would work Let's go ahead and check. I don't know if this meter's got high enough resistance compete capacity to do it or not Let's see what we get. So with this meter. I have nothing. I don't necessarily trust that Let's go ahead and check the frost tip sensor and see if it shows on the meter And the defrost sensor comes in at 36,000 so I think this meter will go up to maybe 60,000 That's the only thing bad about some of these flukes. They just don't go real high in the some of the resistance ranges when they're Clamp meter I'm gonna say chances are that some of our issue there. We'll go ahead and just get a new sensor on there and see how it works See if we can dig that out. They kind of got ice all back in here on that, which is great That's kind of stuck on there We'll see if any pull that thing out. Oh, that's really in there tight We'll see if we can get it out of there. That's in a copper Well there so I'm gonna get my hand torch out a little warmth on there Was able to break off some of that ice All right, looks like I've got one here And So yeah, we'll get that on there Get a couple more buck connectors because we don't have the exact fitting there Actually be better to use some of those Get her juiced up. All right didn't record it because it's just hard to do with both hands, but just use the torch there Kept it away from it. Just let the radiant heat get over there to it was able to pull it right out So we got that out Go ahead and get our new one here in While it's still fairly warm. Hopefully you know maybe Yep, went right in the hole. There you go We'll make sure we put a wire tie around that so it can't pop right back out That will potentially condensate and the ice could shove it out. It's usually with these clines. They do a really good job You're supposed to use the oval not the puncture. It shouldn't be able to pull it out I'll just go ahead and crimp that onto the new sensor here Try your luck Let's feed that through in advance because that may not get through there That thing through there. There we go. Not always the greatest grip Sometimes it almost better off just to kind of use your pinchers and pull it off There we go, and then cut off the excess that we just screwed up There we go. Get my buck connector lined up with the edge of my Crimpler so I know that it's right the very end of the metal Really matter clarity on these. We're going to do white to white. Get the black one there and we will see if this works Okay, so we got a gutter on there Get it plugged back in See if the E3 goes away There we go, defrost. Look at that. As soon as I plugged it in Look at that So we'll get a wire tie like I said on there because I don't want that thing moving It's already frozen to place, but let's see if we can monitor And we'll scroll through here suction temp 30 so it is major now All right, let's make sure I didn't make a mistake here suction temperature SCT. Is that what I had? SCT There we go 32 yeah, that must have been it And I think yeah your adjustment thing there that's for when you're actually Selecting things, you know whether it be your what super heat things like that Just for giggles. Let's make sure everything's still set up correctly I'm going to say I think this is 404 So let's check our refrigerant. So program review We want to go program review try to remember. I don't do these very often By the time you get done you get really good at it, and then you forget monitor super heat soup SUP 37 yeah Just least that it's calculating and now that means it's got a suction pressure. So that's the only other thing We want to make sure it works So let's go for suction pressure scp Let's go to scp There we go suction pressure 31 so it is measuring that that's kind of interesting that it's that high and a pump down state When it's running, we'll check to see what our super heat and stuff like that is let's look to see where our valve Steps ESP Atronic step, I believe zero. So it's all the way closed That's pretty much where we wanted it There was talk about it later that they really prefer a solenoid valve on these now instead of just that Val there as you can see it thinks made America. I think that was probably really cheap not There's your section transducer Just where you would expect it to be at box temperature right there See what our box temperatures. Let's go to Outdoor temperature. That's useful. I would say they don't have that hooked up about barren to get Well, not a surprise. This is a pretty big restaurant chain Well, this gives us a chance to see our coil. Our coil is clear and The heaters are working. I can feel them plain as day Don't see any water building up on my drain, which that's a really nice drain Let me see what our defrost temperature if I can get into the review, which I don't want it Don't want to kill the defrost. I'm gonna let it terminate on its own. So I'm just clicked Yeah, the monitor last defrost laps time DFE. How long did it take last time? Eight minutes So, I mean, it's obviously calculating the advance That way it's not Wasting time building up heat in the box AC power voltage AC just for giggles Let's see what the AC is 26 volts. So whatever's going in must be accurate Here's your defrost heaters relays fans. I really like these. I mean, they're old But I really like them as long as you got the parts for it. It's not bad But we could review it or what defrost type air electric I mean, honestly, it's pretty much all set up right there. You really would think box temperature would be in here Superheat export expansion valve suction temperature suction saturation Fever temperature suction pressure outdoor temperature defrost temp at defrost in DFT See what our DFT is. I see what temperature it is. I bet it's about 60 maybe where it's gonna trigger. I know you guys are where I like well It's this it takes it off of that defrost temperatures probably what they're gonna use I bet Because I don't think they've got a dedicated sensor just for that and you can see the heat It's radiating off of the wall Which is probably why you've got This happening back here. Yeah, see that's That's generating that much heat that that's I had a chisel that off earlier. Yeah, there's massive heat there It really could terminate sooner, but this is not usually one of our stores. So I'm not gonna change anything. They've got parameters. They want things done at yeah, it's 61 still not terminating Notice they use the metal All thread we use plastic bolts that way they don't transfer Through the temperature and they don't rust All right It was about 62 degrees that it terminated and then Fandalay was very short Because like I said, it's definitely getting a little warmer that it needs to almost see if we can review There I had a hit clear test So A&E is electric that is your defrost type next one's gonna be refrigerant type 404 that's correct box temperature. See what that's set for Negative 10 it sounds about right SUP superheat set for eight little on the higher side, but I'm not gonna change it SLA slave operating mode. No because it doesn't have another one DFA DDF I do frost feel safe time. No, I should have one D-Frost 6 That's quite a few of them And then DFF You'll save time 35 minutes. Okay How did that get out of it defrost in temperature, which is the next one? 60 which I went above it, but who knows it was a delay DFS Which do first start time offset hours no offset ALA she's gonna be alarm high five degrees alarm low temperature negative 15 a LT is Minutes And Fahrenheit or Celsius. So for the most part everything looks like it's set pretty normal I don't want to change anything major on it because like I said places like where I'm working at have Exact ways they want it done because every one of their thousands and thousands of stores are gonna be exactly the same Anyhow that's pretty much about it other than going up on the roof and don't check the yet to insert Took me a second to find it. It's like a regular package unit, but There it is Well looks clean Both fans feel like they're running That one actually is running reverse I believe Wow look at this mess Y'all the dark oil That's the problems in here before That's creative Wiretide to wiretide. I guess at least it's wiretide, right? There's your outdoor sensor right here remote fan shutdown Cyclist somewhere in here. There we go. Looks clear to me Clear side glass definitely not clean This thing's been running on prayer for quite a while You've got your cooler and your freezer in here. So Freezer probably bigger that's a hundred or no 13k Versus 10k So this is gonna be your cooler most likely they got the wrong dedicated maintenance people So again, and then you can also tell it's freezer because of the liquid injection So cooling so I Did my part made sure it wasn't nothing else besides just the obvious Get out and pick things up I've got it back on cool and It's 21 in here. You can see That it's feeding tubes The super heat is reading a little high under the circumstances I don't want to dig in too deep on this because like I said to get their own maintenance guys And you could change it to many things And it's like we've never worked here before so it's kind of one of the things where you just Fix it and get out and build a relationship later type thing 34 degrees, but we're only at 21 degrees in the box. So it's going to be high at this kind of temperature in the box Suction pressure is kind of low Which looking at the refrigeration system up there. It doesn't surprise me a suction pressure scp Which could be off 18 anyhow Put it back to cool breeze box temperature. We're just gonna go ahead and wrap this thing up All right, so 317 there Good deal
