 All right been here before for a reach-in on the video or now we're gonna go for their walk-in freezer That's not a real smart idea either. Oh frozen up sweet All right, let's get started this video is brought to you in part by TrueTech tools quality tools essential support All right, so we're gonna have to get a ladder and see if we can get up there and get this thing melted out All right, so we found the controller and the condenser that's dirty says DFO there on that controller, so maybe it's got a failed defrost See the side glasses fool appears to be It's like it's towards the dry mark this got that electronic stuff on there which Could be failing and not a whole lot of room between that ceiling in there Let's find out why it's not we do for Austin. Is it a heater or is it a relay? Is it the controller is the termination switch is that the suction transducer? What's the cause of it? looking for some clues here if you look at the Water in a pan that makes you think it's probably trying to defrost Otherwise, how would you get water in there? So that makes me wonder if the compressor's sticking on which makes me think control there may not be sensing Temperature correctly Set for negative five defrost now and it's sticking on That's what I think's going on then brushes coil off to things kind of dirty pretty decent Maybe not Coming over here to the other side. We've got 14 psi Not sure what it says on the other side if it's just a duplicate or what this is A limited on space, but man it really makes it a retreat to work on Yeah, it was in defrost Look at this I can feel the heat on it and you can see where it's melted the coil or melted the ice off So it's melted it, but the fans not shutting off you can see water over there The fans never shut down so it's almost like a total failure on the defrost point. Yeah Yeah, that's melding as soon as it hits it So let's find out the contact or sticking or what's going on. We're gonna have to melt this Look at that. I just bumped it and the fans shut off So just a snap disc Maybe it was making not making So we can see right here the compressor and the fan are right here on this controller Doesn't show a relay here on this We've got two wires that come out of here Come over to There which goes into this box This one might just control section only It seems as if it has set points C and cut in 20 psi Cut out this is heaven So all this is here is a pressure control. This one doesn't do anything So the other one's going to do all the work Wait to answer and I need to be I want to have him killed breaker this time Get red and black and blue, which only have black and red there Looks to me though. This little controller here must control the compressor That would make sense Yep, right here's compressor So the relay is built into this thing So they got this fancy Fancy little device there to shut the compressor down. So you end up buying a whole new controller. We're not gonna have this So what you can do you can put a low pressure switch on there And we can make it kick on a kick off the low pressure switch, which is a whole lot more resilient than this little thing I've done that before and had to come back and switch it out later The relay there looks like it's going to defrost heaters. That's more along the lines of what we got going on there Um, that was pressure only this one's going to control that control right there is your temperature control Comes down in those two wires there Can't see it. That looks like compressor So this is the one that's sticking That little gizmo there. That's also your defrost clock too. That's what sucks Yeah, so you just gank a thermostat out and it's not gonna defrost So now you're adding defrost clock to it. All right, so it's taking some ingenuity here, but what we're gonna do I've unhooked the compressor wire coming out of the controller Hand to hook the evaporator fans from the motor or from the controller We're going to run this to a two-pole two-pole contactor. We're going to power the two-pole contactor's coil off of the 230 volt defrost heaters And so when they're energized, it's going to kill power to the compressor and kill power to the fan It's generic. It should work Now what but obviously the thermostat's not working so I could wire one of those in But it only has to work for a day or two until we get the other part And then we can reverse it back the way it was. So that's what we're going to do There's no room up here So I'm not really going to show you how I did it plus it's really not something I recommend Unless you really know what you're doing What I ended up doing is I got a 230 volt coil contactor two pole Took the two poles, two power lines off the controller there One's the fan on one side, the compressor's on the other side Brought it through there That's not going to work Okay, so what I ended up doing was for the coil voltage Which is 230 volts on the contactor there it's on the normally open and common side of the relay With the high voltage So when a switch is open you should have the potential of 230 volts When it closes it's going to collapse that which then will break power to the contactor Coil so it's going to be powered Shut allowing the power to go through like it was before the relay was in there and then when the Relay is energized that open switch which has potential on both sides of the switch It's going to become one solid wire so to speak for demonstration or example purposes And that's going to cause this to then break power to the coil and then break power high voltage to that compressor Kind of confusing if you don't think about it But yeah, it's pretty simple Um got it mounted in here. It's going to be inside the box. So we don't have to worry about it I'm getting shorted out or anything like that Um, this is temporary just for a day or two until we get the part So now we're going to melt that coil or I end up melting that ice and make it a warm in there And then I'm going to defrost I'm going to test it out first make sure it works So we can see the fans running there And the fans are running in there Let's put this thing into a defrost and see if they shut down Making sure nothing's going to short out everything's insulated Let's hit the defrost button Look at that compressor shut off Not bad for an amateur youtuber Good deal and kind of see Some steam here and there Yeah, so you get that back side That heater's got to melt all the way through it. So what I'm going to do I'm going to let this thing do its natural thing And then we'll get the pump sprayer out Get most of the work done for me. You can see the water's already accumulating I don't want to pump more water into that Then we already got because then we're going to overflow We're going to let it do just bare bone minimums. Let's let her run All right, so Got a pan catching here a pan catching there All that stuff fell most of it All fell off the coil Actually, all that fell off except for the one edge corner Probably got a little bit at the back too that might fall Um wiped up this floor So I gotta get some rags and wiped that all up because you don't want that to freeze in here That worked out better than normal Just because the extra water like I said would have filled up that pan and it would have went potentially all over the place Oh, it hasn't kicked on yet That's still running Yeah, it's still burning up See if we can scrape some of that crap off I'll trap that heat over there on that side See if we can peel this off. Yep, good. I'm gonna peel this off There's your defrost termination limit switch over there Fans feel good That's good This little gizmo here is made for scraping Gaskets and stuff like that. I got the razor blade flipped around to the back side Should be able to cut right down Get some of that off Not hurting the coil none. It's definitely thicker at the bottom We'll melt the rest of it off before it just kicked out That's a great. Let's go ahead and turn the breaker off Just like I worried about I got water everywhere. So I'm gonna go grab my Vacuum and get that sucked out of there. Otherwise it's going to freeze in between the ceiling and leak down 38 area it's dropping I took that top shelf off through it up here. They don't need to block in the exit of the uh, the way we're coming out Okay, what I want to do because it didn't bring on the compressor right away just brought in the evaporator I'm going to throw it into another defrost and see if it kicks out normal And if the compressor will start back up because the last thing I want to know is Hour from now or two four hours, whatever That this thing doesn't run like it's supposed to let's try one more time Yep, it did it Shouldn't run for very long. We see where we get the wires and stuff I'll kind of it's well below the top of that Nothing's going to get into it and it might put the cover over it'll be all safe Good enough to get them by otherwise. What do you do? You gotta get another mobile cooler up here freezer up here And we just used ours over the weekend for another emergency. We've got two of them and they're both used up Get these pans out of here now Think our dripping's all good for now A little bit back here in the back. Oh, good grief All right, so kicks out of defrost Contactor pulls in which means this should be getting power, but it's not Don't know the system reason that I don't know if I should just wire it hot and all the time or not I mean when I turn the power off and back on again It came right on so I don't know if there's a delay in the compressor, but not in the evaporator that seems pretty Pretty fishy There should be a delay even in the fan, but obviously it's not coming on right I did match them up left and right to the right one far as I know Yep, there it goes All right good. They must be uh, I don't know. There must be a delay there. The very first one's the fan That comes down goes to there and goes to that. So that's the fan. That's correct. The compressor's number two. Number two comes down That then goes down to there So there is a time delay in this thing here Um, because this not only does it come out of here But then it also comes to this and this is the low pressure cut out Which I think is all it's doing is low pressure cutting out it's not I don't know why you'd even need The low pressure cut out honestly because it doesn't have a solenoid to pump down So it's a point why not just have a low pressure switch I mean other than just monitoring the second pressure, which It's just one more thing to go wrong Side glass is full Which is nice Got that pan down low enough that the water should boil off Well, we're gonna watch this for a little bit make sure it's down to temperature We'll put those panels back up there and we might call today All right guys, we are back. Looky what I got. Got me a little Dixel here. Little Dixel control. That's right So let's get this back in there and see if this thing works. Let's see how well my remedy worked at getting the Coil from freezing up again Cool Looks like it must have worked Look at that Looks all clean to me Cookies are frozen. Yay, let's get this thing changed. Okay walk-in freezer. Hmm There's no solenoid to pump it down. So don't really matter whether you just turn it off or not You see we've got the water and the pan there So it did melt it out like it should What we're going to do is we're still going to utilize this contactor to kill the compressor So the controller's going to control the contactor like you should have been done to begin with Similar to how they're doing the defrost relay there for the heaters that way it lasts longer All right, so we've got The orange wire coming off what it would be the compressor right there That wire is coming over here and going to my contactor's coil The opposite side of power going in there is coming off of the terminal strip over here That's going to the other side of my coil Then the power for the compressor is getting its power from the same place the controller's getting there from Passing through the contactor going then on down to the compressor Basically, it's just an isolation It's going to take instead of the amperage going through the little lightweight contacts inside the controller They are going to go through They're just going to control the coil voltage, which is still 240 volt But there's no amperage behind it. It's just going to control the contactor And we got everything ran through a little loopy-doop there I wish I've got to get this other one up here and through one of the Islets here and then we'll mount this thing inside this box about the cover back on and everything will be good I did hook the fan back up to the original spot The fans are not ready for a whole lot as you can see right there maximum current on this Thing is 16 amps 5 amps for the fan Which leaves you what about 11 amps for the compressor That's why I don't like that rated load amps is 8 I mean, yeah, it's Minimum circuitry 11. So I mean it's a smaller compressor, but still it's going to make it last longer. It's Cheap insurance. There's a short in the compressor. It's just compressors with your poles down how long ago I think two years ago This is going to take care of any shorts. It's going to burn up the 20 some dollar contactor versus several hundred dollars Controller we've got our mounted down there in the bottom With your screws all the wires are clean and clear away from All the metal everything's ran through the Islets everything's back to the same We're gonna mark in here what we did on the Let's go ahead. It's kind of hard to see here, but so number one here Was power going to the controller. So opposite of that would be two that is going to be What comes down goes over to the coil The one coil gets powered off the side of the compressor So that's your coil. It's really in there's your normally open switch. That's the isolation contactor. There you go Simple as that Most people don't figure that out without the wiring The one had just bit it just to be safe in case of somebody that doesn't have as much experience Got the cover on I'm gonna leave them a note here I'm gonna leave this other controller here. It's good enough to get them by if this one would take a complete crap What I did how I did it And then on the other side it's got the instructions on programing it which I gotta double check to make sure all that stuff's correct That's who's running All right, she's running With your defrost terminated like it should and throw all this back inside the bag And we'll wrap this thing up
