 All right, so we've got a heat pump that has oxygen reheat, which is gas furnace and it's not running. Look at that. See water. That ain't good. All right, let's see if we can get into this thing. Love is running. She gave up. You're going to quit on me already. Let's see if uh, luckily that didn't pop. The infamous 32. All right, 32. Relief's pressure switch. Let's take a look. 32. Low heat pressure switch. Not closing or reopened. And here's all the definitions for it. So let's dive in there a little further. Uh, it could be low pressure gas too. This has propane, so so the propane comes in through black iron, which is nice. Comes over down and so let's see if that's closed and then we'll start digging in. Don't want to start moving things right off the bat, but I want to know what's going on with this water here. That don't make no sense. Looks like it's coming. Come in there on that coil. I wonder if we're plugging up. Now I doubt it would be that good to do to there. Hmm. Don't feel anything leaking up here. There's no water lines up here. I don't think. Exhaust stacks two and a half inch, which is that weird old stuff. I think that's two and a half. Yeah, it's two and a half. All right. Let's go ahead and get the heat first and then we'll figure out what the water's from. Okay. Now get side tracked. All right, so we checked consane trap. It's clear. No water built up. That's usually one of your biggest problems. Now we did just get a bunch of snow, so I'm wondering if our exhaust stacks might be plugged up. We ink this burner box off open here and see if there's anything going on in there. I did check my switch here. It is closed, so it's allowing power through. We're going to start it up again and then we'll open up that box and see if it comes on that way. Here's a little trick I'll use. I'll cut this thing about right here. Move this plug to there. Then that hose gives me something to use to get down in here and blow through these here. Now the best way to clean this thing out, obviously, is to take these clamps off and wash it out in the sink. But if you have one that's glued, you can blow it out, whether it be with a hose to make it easier to get into, if you can't remove it, or CO2 cartridge works kind of good too. But flushing it with water is the best thing and shaking it and cleaning it all out. So throw that out there. Okay, I reset it. I went back to the heat pump, but as I cleaned up some of this water, look at that. Somehow it's supposedly taking it off of that freaking pipe up inside there. I'm assuming. I love it. It's locked in there. It's locked in there. It's almost like the freaking, it has a good chute in it. It's on the positive side, so it's almost impossible. Makes me think, I'm sure how it's happening. But they got this back to the, I noticed the humidity in here was 50% on the thermostat, which, got to see if this thing's hooked up to the thermostat or not. It may not be. Good grief. This is something weird going on here. Let's figure this out. Also kind of concerning is the pipe's not hot, so I wonder if the heat pump's not working right either on top of everything else. It's not working right. It's nice. Let's see how this set up. They do have the humidifier ran into here, so they're looping it still through the humidostat downstairs, which they don't need to do. So we're going to have to fix that, find out why there's a water leak, and find out why the furnace is not running. When I come up here, set auxiliary heat. I have a funny feeling this may not be set up correctly. Let's go through and make sure the settings are right. Set up for heat pump furnace humidifier. That seems correct. All right, so we went ahead and unhooked this. Got it wired directly down to it. This is one of the biggest things I see wrong usually, and I don't know if it was like that or not, but it's supposed to come straight in, hit that, and make sure this locks in like that. And then if you got to do a little bending, make sure that thing stays as level as possible so it doesn't trail back out of there. So we'll make sure everything else is okay. It so far seems like everything's wired upstairs correctly. So let's go ahead and finish checking some of these other things out. So all of our wiring looks to be correct. They got a common wire sharing to the humidifier, to the outside unit, and then down there to the thermostat. So I got good there. Here's the humidifier coming on brown, heading up there on the two wire. Everything seems to be correct. So we'll go ahead and try this thing again. When it came on a second ago, it was the blower and no, I don't believe there's a call for heat. So draft motor seems to be all right. Igniter is one of the newer style. We're not tripped there. We'll still go check for intake yet. So let's go ahead and dispose of Lee. This has been checked. We'll make sure. Oh yeah, it's new looking. Still ain't sure how that water got through that. That makes no sense. I'm gonna check inside here. See if there's anything in there. So we don't have any water down there at all, which there shouldn't be. Everything looks fairly okey-dokey up there. Our burners actually look pretty good. No real rust in there on that, which is nice. Looks pretty good, pretty good. So for LP gas, that's pretty good there. I'm gonna go up there and turn it back on, see what we get. We'll go ahead and see if it runs with the cover off. We're calling for auxiliary heats 25 degrees, lockouts 30 degrees. So it should start running. Key what we got. Major heat coming back at me, which is a good thing. You definitely know when those heat exchangers are starting to plug up. So here is this thing. Looks like it is a 06 on that also. So with it having the heat pump, it doesn't run near as much. Like I said, heat pump shuts off at 30. What I'll do is I will cut the cover on slowly and see if it sucks it in. It sucks it in pretty good. It ain't horrible, but it's definitely pulling on it. Alright, so let's put this back in there and seal it up and see if it will start over on its own. Since it's running now. Okay, it's still sealed up and running off a little better. Let's go ahead and kill it and see if it could start over on its own. So it should go on a complete cool down and start over. This is a timed on to second stage based off of the algorithm that control board comes up with. It didn't wire it up to automatically stage up thermostat, but just one of the few boards that actually figures out the algorithm and does a fairly decent job at it. It's a cumulative run time. So unlike the other ones, it's 10 minutes, 15 minutes, 12 minutes, whatever they got a time or so for. So let's just a touch and see what happens here. Alright, so we do have atomized mist up here. I think what happened was that since it's a recirculative humidifier, it just goes down, up, down, up. It was running so much that it was just going to do so high that it was just condensating. So I mean, you have high humidity coming in, going out. It's the only logical thing. It surely isn't from watermine dripping. Nothing up there is wet. We have nothing in the evaporator box. And like I said, it's 48 percent now and it's 50 when I got here. Lucky there. Let's do it again. That's a 31. 31 is heat pressure switch did not close or reopen. So it's acting stupid, but yet it's still trying to light. Makes no sense. Denied. Start over. We're going to go grab our manometer. Check to see what we're actually pulling on this. It's only a good way to know what's going on. Alright, so they have concentric kits, so we know it's not an air intake issue, most likely. It's like it's ran too much. At least it ain't packed in ice. So let's go ahead and go back inside and check see what's going on in there yet. Alright, so I went out and grabbed my manometer. In the meantime, we got a 31 code. Now it is high heat pressure switch did not close or reopen. So one or the other. Low pressure switch or relay did not close or reopen. So let's make sure this is all connected right. Seems to be open. Alright, I just tried blowing through this and it did not want to let nothing out. Clear on this, but not on the box I don't think. Let me take a look inside there. Okay, so went ahead and yanked out the condensate trap, got the end draft motor there, and sure and lo and behold, things aren't looking too good. Looks like delamination to me, so freaking heat exchanger is going to need replaced. Sometimes I'll pull the blower motor to make certain, but you can see how little holes got crap in it. Not my ideal of a good time. I'm going to call back see if we've had any history of this or not, but it's looking that way. I'm going to look at the blower section just to make certain I got stuff eaten through and it's it's shot. Well, luckily I brought the flame sensor out because you know how easy it is to get into it and that looks like crud. So we'll get that cleaned up and let's get that blower pulled out of there. Something tells me that this long stripped wire that was set in by the furnace had a dual purpose because if it's just perfect and when you blow through it now it's just terrific. I would say this has happened before and guess what, it's going to happen again if you don't replace heat exchanger. So that's what we got going on. Always something. I think it was setting up there. So yeah, we'll go ahead and this will run when I get done, but the problem is it's like I said it's going to happen again. So heat exchanger is going to need replaced. I'm going to go ahead and get the numbers off of this. I'm still going to check the blower and make sure that there's nothing down there, but it's pretty obvious what's going on. All right, we're going to see if we blow some of that out, but the heat exchanger needs replaced. Probably could rinse it out, but it's going to plug up either way. I just need to get the new heat exchanger. So let's go ahead and get this thing back together. The system should run now and we'll get that stuff taken care of. All right, so we just ran the test through the furnace. Now we're checking the humidifier. It's working. So the humidifier is fine. We got this set a little bit lower now, so hopefully it doesn't run. So now we just got to try out the heat pump. All right, heat pump finally came on. It had its own internal delay on it. This usually don't run unless it's above 30. It's getting hot and I guess this was checked not too long ago, so it should be fine. There's ice on the blades is why it's shaking a little bit. So basically we're going to get them a new heat exchanger and get that changed out. Hopefully blowing that out made it, we'll make it last a little longer, but we should be able to get back shortly and get that changed out. All right, so we're back. We got this heat exchanger taken out. We got the new one built. Now I'm going to point out a couple things here. This right here is one of the most important things that gets forgotten sometimes. So make sure you don't forget that thing. That goes between your top primary and your secondary. And what that does is when the blower is blowing, it causes it to ricochet to the front of the heat exchanger and then go on out. If you don't have it there, the air goes straight up and the limit will start tripping and your temperature rise. Everything will be out of whack because you're not moving the air across the heat exchanger before it goes on out through the ductwork. Not all of them have this, but you got to make sure you always check all of them when you do this because they don't give this to you as far as I know. It's not even in the paperwork to know whether or not they've got it. We're going to look at the delamination here in a minute. It's really weird when they put this thing together at the factory. They include the living crap out of this thing. I had to pry that off. That's how bad it was. And right now I can't even get it off. It's a little prying at it to get this thing off here. Yeah, it's really tight. Not sure why. I've got all the screws out. So let's take a look at this heat exchanger secondary. All right, so here's a better look at it. You can see it's delaminating. You see the white back here in the back compared to this up to here. The white's gone. It's kind of hard to tell, but you can tell that that's not fully open. There's one piece. You can see it right there. See how that's, yeah. Just got gunk in there. They don't have it. There it does. So this is something to keep an eyeball out for. These don't always rust all the way through. This one here didn't. Usually you can see something wrong coming through. Try to look at this other side. I'm trying to remember which side's which. Usually you can see some white stuff in between here and stuff, but I'll start letting go. Now usually I put this thing all together and tear it all out first. As you can see, there was no thought put in there where, how you get that in there. That one there's easy to get to. No screws in the way. This one on the other hand. Again, I gotta use two extensions, and you can get down there, but you can see the screws block you from coming straight up normal. So yeah, we got it in there. That's supposed to go on the bottom side of it, but I don't think the thickness of the metal there is going to make a difference. I've actually lost these before or didn't know where they were or whatever, and actually made one out of a piece of sheet metal and screwed it down into here and here, and just didn't make it as best as I could. It worked out fine, but you definitely gotta have it in there. Just thought I'd point that last thing out there. Other than that guys, just check everything. Don't stop at one and just keep going. So until next time guys, catch you on the next one.
