 All right, today's project is the ice machine here is not working right. Oh, wait a minute. This is a heat pump. Okay, so we're slightly froze up here. And so they turn the breaker off and you can see that's pretty thick. It's not just a like coating, basically we're going to have to get this thing melted down a little bit. Even if I put it into defrost, which I don't think is working right, obviously. So he's able to dig us a little trail into the control panel here. Not sure what brand this thing is. It is 410A at least. Oh, look at that. It's Nordine. Good old Nordine. All right, so let's go ahead and put this thing into run and see if we can put it into a defrost and see if we can force it into defrost over and over again to at least get some of the ice melted off of it. That way we can melt the rest possibly with water, which is really great. But there ain't a whole lot of options out here right now. It's well below 30 degrees and it's going to get even colder throughout the week. Defrost is set for 30 minutes, looks like I don't see a speed up tab anywhere on there. All right, so we see how to do it. Let's go turn this thing on and see if we can make this thing melt. I've got to admit I did not know this thing had emergency heat on it, so it does have it. Which is great. So we'll put it on heat, turn it up just a touch and let's go out there and see if we can get that thing to come on. Now the furnace is down there in the crawl space. So I'm not sure if it's gas or electric yet. Like I said, I've never been here before. So she's running. Let's see what we can do here to make this thing jump out. So let's get our jumpers ready to go and see what we got. Now let's see if this works. That didn't work very good. That did not work very good. It says take common to defrost, which I would have figured had been shorting it out, but evidently not. Test pin to see on the terminal strip. We are on the terminal strip. That's common and we took it to test and it said leave it to lay a thing there. It would have mattered whether I did it common here or common there and it turd just did whatever it just did. Well you can see the kind of quality of people that installed this. I couldn't make it over to parameter tile and let's put a T in it before the trap. All right, so let's get into this thing and see if we can find out what blew. I'm hoping that they didn't cut corners to the point where they didn't least put a fuse in there, but let's see if we can find out here. The 5 amp fuse there did blow, so we'll get a new one of those in there. It looks like they've got three strips, very about 15kw in there and gives me a chance at least to check the filter and all that, so all that's good. They do at least have insulated duct down here. Let's go ahead and get that fuse in there and we'll see if we can get it running again and get this thing defrosted. Let's see if we can get this into place here. There we go. Here goes the heat pump. You know I haven't even checked to see. Is it putting out cold or hot? Come on, fan, turn on. You notice it came on immediately and the fan's not running because there's a delay in that thing. I wonder if we've got a contactor sticking. We may have a contactor sticking. It's starting to warm up. Yep, it's starting to warm up, so at least it's running in the right direction so we know we've got a reversing valve working. Nice of the fan to come on. That's nice. I suppose it's kind of got a little rounded thing here. So it won't short. I just... I'm not a fan of freaking Nordine. All right, well, let's get this cover on here. We'll go outside and see if that contactor's stuck. Didn't even get around to it. All right, so put some foam here in the top. That'll make a cap for that so it'll properly trap. That's getting pretty warm, especially for being cold. Cold can be outside and being full of ice. So I'm going to say our refrigerant charge is probably okay. Not granted, the fan's not blowing. So it could be a little off, but check that filter there. There is no filter in there, so I'm assuming it must be upstairs. I'm hoping in the return air, most likely, and one of the grills on the floor. So we're going to crawl out of here and go see what's not working. All right, this is electrical stuff. So for our homeowners out there trying to get out of the pan somebody to come out, do not do what I'm going to do. It's not safe, kill yourself, blah, blah, blah. Don't do that. So the contactor's not sticking, which is a good thing. Not sure why it was running that quick and the fan's not running. It could be because of this jumped thing here. I have no idea. Not my brand. Yeah, look at that. Instantaneous. I'm kind of curious, let's turn the thermostat off and see if this thing shuts off. Maybe we got a fan motor. Because the house is really cold. Like I said, the people that are here are not here. So I'm not getting good stories. So it might be just a matter of the fan's not running. But that wouldn't cause our... I wouldn't figure that would cause our outdoor hint to freeze up. Okay, the fan is running now. I'm kind of curious why the fan didn't come on as fast as the other thing did as the air conditioner. Let's turn this off. Come on, baby, shut off. Okay, there it shut off. Let's see whether the fan shut off. All right, so here's the filter. One of them, I hope there's more than just one 10 by 20. And the fan did shut off and I turned the thermostat off. So let's see if we can find the rest of them. I'm hoping they have these in all the rooms. And there's another one. It's got some washable media in that one. All right, so I looked over the house and I found just those two returns which does not seem like it'd be enough. This thing's been installed for a while. Anyhow, it came out here. The system's turned back off. The contact is plugged back in. It's not running. So I need to set there. I'm going to check my defrost stat on this thing too. See if that thing's closed. It should be probably that yellow thing down there to the left. I'm going to assume it's probably it. So I'm going to see if that's closed. Maybe it's never going into a defrost. All right, so I'm looking at the schematic here. R2DFT is your stat. Drops on temperature drop. Closes on temperature drop. Obviously you can hear it ringing the bell. So it's closed, which is a good thing. So we eliminate that. Let's go ahead and get this thing up and go on and see if we can reread this a couple more times. Usually you just jump two wires together nice and simple and it goes into a test, but they had to make things more complicated. So let's look at it one more time here. So we flipped it back on and the fan immediately came on. So maybe I did something out of order down there. Maybe it took a couple seconds, a minute, whatever for it to get its brains back together. Hard to say. So we've got it back on regular heat. Let's go back outside and see if we can get this thing to go into a defrost. All right, figured it out. You've got to take tests to common. So we're putting it into a defrost. Let's see what it does here. The fan's shut off, which is a good sign. So we're basically running emergency heat mode. Our sail auxiliary strips are on. See if this thing can start melting some ice. Now it's only going to be able to melt at the coil. It's not going to melt two to three inches away from the coil. So at that point, that's when we're going to have to melt the rest off of some water or whatever. But yeah, we're going to let this thing melt for a while. So I'm going to let you wait for a second and see what happens here. She's been running a lot. You can tell that kind of crazy amount of ice. That's pretty crazy. Now it's just the compressor running. It's only pulling four amps, which is kind of low, in my opinion. This unit is a two and a half ton unit. Full loads, 14 rated load, I should say. So, huh. Anyhow, let's go ahead and let this thing run for a bit and see what we got. Let's let it run. I'm wondering if, like I said, if that board is defective or is our defrost termination defective. So I'm just going to let it run for a bit and see if we can get some melting going on. Notice there's nothing below water-wise. And you can hear it making some noises. So I think it's starting to melt some of it. Hard to say. Alright, this has a 10 minute override, so it came out of it. So let's put it back into it again. Here to this one. Going to defrost again, that means probably that stupid stat has already opened up. So let's take a look at that stat and see if it's open. Alright, according to that, it is open. So our stat is prematurely opening up. Or it's been yanked off there, wherever it is. Like I said, it's a red wire. It's probably, yeah, there it is. So it's down here in this very bottom corner. So let's see if we can get this thing melted some more. We'll go ahead and jump the stat out. That's our problem here, I think. It's prematurely doing its thing. So we'll go ahead and jump out the stat. Once again, don't be doing electrical stuff. You guys don't know what you're doing. Disclaimer, disclaimer. Disclaimer, disclaimer. Alright, now let's try to put it back into it. I'm going to defrost. Find out which ones are common up here on the contact or it might make it a little easier for me. Alright, so obviously the black one here is my common. So I jumped it out. We're going to start our timer again here. We'll keep track of that. Look at that. It's actually starting to melt the ice off. So I think our biggest problem we're going to find is that the defrost termination is prematurely shutting it down. It's never completely melting the ice off because from what I'm seeing, it looks to me like it's melting it off like it should have. But what you're going to run into is the icing going to come off our squat right now. So we're going to let this thing continue to go through its thing. It'll actually, what we could do until we get back, we can just leave the defrost. Shoot, yeah, we can just leave it jumped and that'll allow it to calculate all the time and it'll go off on time instead of temperature, which would get us by saving a little bit of money versus running electric strips. But like right here, either it does it by the board recognizing it's reached 68 degrees, jumpers removed, or 10 minutes has elapsed. So that'll be good enough to get them going back to normal. So it's starting to make a little bit of a difference there. That's got that big flat grill style to it. But yeah, let's keep on letting her do her thing here. Okay, so we've scraped some of the ice off of it, which is doing a lot better. The inside is starting to melt pretty decent. Now, here's the problem. This thing has quit in defrost mode while the defrost termination switch has actually jumped and basically it stopped at about four and a half minutes. So I'm timing it again to see if it will continue for the whole 10 minutes as it's supposed to. If it don't, and what I'm reading here on the old paperwork there, if things aren't right, you just replace the board. I don't see anything else that would cause it. I mean, it's pretty cut and dry. This ain't no fancy board. So we're going to try it one more time here and probably just call it a day after that because I mean, if it's not going to defrost to the point where I was trying to bypass the switch to get us by, then there's really no sense even bothering with it. We'll just leave it in auxiliary heat and let them finish until we get the part and then maybe it'll melt off by then depending on what the weather does, which I don't know if we'll have it in a couple of days or what. It is a Westinghouse, so it says, but Nordine, whatever. They got to me doing different names. All right, so we've got a good majority of it out. That way, if it doesn't get warmer, we won't have to spend a lot of time here when we come back. We got most of it dug out that I could get. But we're going to order that switch, defrost termination switch and a new control board for it. I redid it multiple times over and over and over and never did it once go up to 10 minutes. Sometimes it's only a couple minutes. Sometimes it'd be seven minutes. Sometimes it'd be four minutes. So we got it as far as we can get it. We got most of it knocked off. We're going to get those things ordered and we'll be right back. For right now, what we did is we unhooked the common off the contactor and I'm going to leave the breaker on that way depending on how they got this wired up. It can help keep that whiney's warm. I don't know if it's got a defrost heater on it or not down there. I can't hardly tell. It may not. I know mine personally doesn't have one. It's a different brand, but just don't see it as often with the scroll a lot of times. Anyhow, we'll get back out here and we'll go from there. I told you if we came back, it might get colder and that ice wouldn't melt off. Here's the reason why I went ahead and melted it off while I had the opportunity to do it because lately it's been pretty bad. As you can see down there, nothing's really melted. We got our control board and defrost termination switch here so we're going to go ahead and get those things wired up. All right, so we got the power off. I left it on while we were gone that way if there was any type of resistive heat or whatever through the compressor that at least been powered. Whether or not it made a difference, I don't think it probably did, but it made a good attempt anyway. I'm going to point out a little trick here that I've been doing lately. Pull out your bit from your little Klein handy dandy small screwdriver and if you got, well, those ones there are the old school ones but you can literally stick out over top of it and pull down on those plastic pieces there. I might be able to use my regular Klein. Let's see if we can do it with that. That makes it a little easier. You can squeeze them with your screwdriver and stuff but this sometimes makes it a little bit easier. Let's see if we can do that. Yeah, it's too big. So, yeah, I've used, I guess we'll just use pliers like normal. I just did it on a couple other true electronics type boards and worked out great but, yeah, let's do it the way I've done it for the last umpteen million years. All right, so we got it all out of there. This new one came with this little flappy plastic thing here. It's like a range shield to help protect it. Got rid of that stupid sheet metal there. They just locked in there so we got that out of there. Got the new defrost termination defrost switch installed. Did put it back in the exact same location. I added a wire tie to it there. That way the water will go down there and hopefully drip away from the switch. They didn't say anything about it, but less direct water going into the switch the better. So we've got that in there. So we're just going to have to get this thing back together, kick it on and see if it does defrost like it should. All right, we took it off emergency heat. Got it 62. Let's go out and see what we got. Gonna have to assume that it's no time delay. No LEDs on this because that obviously is too expensive. So we'll give it a little bit here. I don't know if it's got a speed up timer. It says delay with a little jumper thing here and it's no delay. So let's get rid of no delay. Let's get rid of that. There we go. No delay now except for 30 minutes of runtime. Doesn't seem to be doing much. All right, don't forget to turn the power back on because that'll delay you a little bit. Had to make sure I had power here. So anyhow, it's running now. Thank goodness. Thought we had a bad board. Shouldn't have to jump this thing funny like. So let's go ahead and put this thing in a test mode. Which this one's very particular about its common wire. There it goes in defrost. Go ahead and start our timer. Also as I was reading through the paper there, that delay there that we was looking at, that ain't the delay like five minute time delay for kicking on the board. That's a delay when it goes into a defrost, like a quiet defrost that carrier would use. So that's what that delay is. And they don't want you to use it on a regular reset compressor. This is a scroll so it's fine. If you have a reset compressor, they said do it only if you've got a hard start on it. So she's running. Let's see how long it goes for here. Feels like it's in cooling mode. Let her run for a little bit and see if she goes for the full duration that she needs to go for. Okay, just kicked out at about two minutes and something. I have a feeling that the heat shut off. It took a little while to get it switched over. I think so. That's not no delay which is what they wanted me to do. Let's see what it's got as a delay. Oh well, whatever. I'm going to re-through that again. Alright, so their instructions are so billow-backwards. If you want delay or if you don't want delay, put it to delay. And it's just like don't tell you to remove the jumper so you can short off the transformer. So I went ahead and jumped out the defrost switcher because it kicked out. Well, I want to know if this will run for the full ten minutes if I leave that jump together. That way I can kind of know for certain if that board was fluky or if it really does what it's supposed to do because in theory when that thing's jumped like that and it doesn't open like it's not going to, it will run the full ten minutes. You know, it's just my luck that it just starts snowing and sleeting and stuff like that. It's perfectly okay a little bit ago. So good time for that little sheet of plastic there to protect the board I guess. I'm trying something I've never tried before. I blocked the top to see what kind of heat I can trap in there. See if I can melt some more of that away from the coil. It might be working. You wouldn't figure it would, but worth a shot. Plus I got ten minutes to kill anyway. The heater was getting close to 62 and we are getting the auxiliary heat work and that's what I wanted to make sure of. So I took it back up to two more degrees. Still timing it out yet. Alright, so it's still terminated at six minutes and a half. So obviously their paperwork isn't worth a crap. So we'll go ahead and undo that and put our switches back together. So anyhow, it works now. Alright, that's going to wrap this one up. Honestly, did the board need change? I'm not real sure now. At this point when the factory gives you bad information and they say that if the defrost board does not open and it will run a maximum of ten minutes and it only runs six or seven or five I mean it did all kinds of different ones. It's been a few days since I've been here. It leads me to believe that factories should know what they're putting in there what it is supposed to do when the defrost doesn't open. It doesn't say a whole lot for the quality of the product. I know there's a lot of good ones and bad ones out there but you know I've always been Linux and Carrier but I am not impressed with this thing at all. I'm going to wrap this thing up. It's working, it's shut off and we're going to head on to the next one. Until next time guys, if you want to see more like this you know what to do. Later.
