 This video is brought to you in part by TrueTech Tools quality tools essential support What is going on guys? So guess what? We are back again on this train unit It is the same one that I replaced the evaporator coil on and now I get to replace the heat exchanger Because the little spirals that go inside the heat exchanger to get it to turbulent they were bad And was causing direct impingement on the metal and the heat exchangers garbage So hopefully we don't have to yank the top off But we're gonna try find out how we got to get this out because I haven't done this particular model I did the older voyagers and those were kind of a pain in the butt. All right so first thing I did was turn the power off which is Going to cause the fire alarm to sound a warning because The people that wired up the smoke alarm wired it up so it's powered off the unit and not off a alarm panel I told them what was going on where I started here's those junk spiral deals that Went bad and caused the impingement This was being taken care of by another company prior to us And this was my first winner working on it. This was the first time we got to check the heat exchanger So I would have figured they were paying people to maintain it that they would have checked the heat exchanger But obviously they weren't because the size holes that you're going to see in here didn't just happen So right there's the new heat exchanger. I don't know if they got one It's actually got some stainless steel on it, but it looks like it Actually is not the traditional junk galvanized, but I could be wrong I mean it seems like it might have a little more stainless in it, but it could be wrong, but It's already got the little spirals in there. We'll uh get that installed. I'm hoping That it pulls right out. I'm gonna run my little heater here. I uh usually use this in my garage, but it's uh 35 to 55,000 ht It kind of bounced the heat off to your face isn't like completely icicle It's not horrible out here, but it's just when you're going to be out here for You know a couple hours. It'll make it a little bit better. So we broke that use loose and we've got this tuned up here There's an inch out these wires. We already marked them on the gas valve. It might not be that bad at all I bought got new igniters and burners and All that Funky looking weird thing. Look at that The draft motor out put the extension on there That'll allow us to get back in here to this Thanks screws here in the back. So I went and grabbed my longer extension here Makes it a lot easier to get in there nice and tight spots like that So we can pull it go ahead and pull that out. I've got a roll out switch here. We got it unhooked and then Finished taking out a few more around the corner. Hopefully this thing pulls right out, but I bet you it won't we'll see So we got the burners undone here You can see they made them off some nice shiny stuff that won't corrode But that part there is not the greatest Some of these look worse than others went ahead and just ordered new ones See the new one looks like that there. So We'll go ahead and get those swapped out. We'll put the igniters and stuff in right before we slide it in I don't want to get them broke or anything like that. That one limit thing came right out And just got a few more of the screws My hope is to be able to shove this back in there or worst-case scenario move it off the side and pull that thing out Not overly impressed with this design. They just etched out a corner so they could save a couple screws And then if you don't have it perfectly aligned you got to fiddle farther around with stupidity here Just something more to complain about And like I said these here they got the screw from the other side That won't be real bad on this one. I went ahead and took some more screws out here on the side A few more on that side. I'm gonna try to get this out. I went ahead and yanked the insulation out of top Got it saved over there. We can glue it back in Some of this is going to get destroyed. It's called collateral damage That's not going to give me a whole lot of extra there, but at least lets me know where things are at All right, so we've got it loosened up Kind of shove it in Hopefully we can kind of get to the screws that are going to be Lining up with that right there just like scooby-doo. You just got to push the secret button It goes right in there and I didn't tear anything up that allows us to Heat exchanger feels loose in there So if we can just get it broke loose down here, it's coming out. I don't care if it comes out of the torch It's coming out We'll uh pick those out And you wait until you see this heat exchanger. This is absolutely Crazy, I think we're screwed down on the bottom if we are that's I'll pry that sucker up We have to go ahead and just unhook some of the wires mark blue to blue So I know where it's going there and hook the flame sensor around to pull these wires back through like I figured Protects the wires as it goes through the thing out through the metal Everything was loose up here, but there was one little screw That was stuck right there which we popped it off And it is starting to pull out now Looks like they at least made the line set here high enough that it should pull underneath There we go Right there's probably one of the most useful tools guys five sixteenths quarter inch you guys One-way ratcheting so you don't have the little button to break off So I kind of like that better got it down in the links down below There's there's there's multiple links down there the one that says my main tool bag It'll take you to the amazon links everything in it, but some people say they have problems So I just put individual links down there too But if you want to see everything click on the my tool bag one and it'll take you to everything You support the channel doesn't cost you anything more if you want to great if you don't whatever If you know if there's something you can get through true tech tools get it through true tech tools Just use my link to get to them that way I get some sort of credit for at least advertising for them But that's how you can support the channel So the previous company was supposedly servicing this yeah, this didn't just happen like In a day or two that didn't just start to happen You can see the other ones down there in the bottom That's uh There's little turbulators in there Spiraled it direct impingement right on the metal sad is as you could see it right from the freaking front Might as well as not even had any service on this thing because I mean they caught nothing on that And the leak and stuff they never found the leak I mean basically they didn't do much of anything That's why we're changing it Pretty obvious to me. All I did is run my camera down there And uh seeing the plane this day. I mean you when you looked at it you could see the turbulators were broke And you knew that wasn't gonna work. So you can see I got snagged on the way out Ain't much you can do about that. You've got to get that piece of metal right there He'd change her up on top of that probably put some silver tape on that And then when we get it in here We'll slide it on. I don't know why they wouldn't put a piece of sheet metal down there that would protect this from getting tore up and uh Make it easier Got a little bit of our uh Silver tape on there. We're all re-secured. They got those Metal things right there That's what's digging into stuff Look at that They don't they don't trust it's gonna hold itself So instead of put some heavy metal clips on there They put this lightweight stuff on there to hold it That way it can get caught and rip things on the way through when it up down it's flattening out That bend piece so it doesn't snag it on the way through And we should be able to get it in there and slide it into place. Hopefully So like so much you can do without ripping something So what you have to do is press in on the bottom lift it up try to get that top screw in So that the holds the heat exchanger up off that silver down there Got that repaired Right now I'm trying to manhandle and get that screw in from this side Why they didn't send those separately so they would potentially get broke So one of the tricks I'm figuring out this long freaking extension there You can actually get down in there and get the screw Into the heat exchanger I've got two of these It is not easy Your best off to shoot for the middle one then you can kind of Rig them a row it same thing with this here. Well, I finally got Screws in there the ones at the bottom are nearly impossible But did get them what I'm gonna do Get that insulated They had a piece of wrapped around it Make sure this all tucked in while we can get to it nice and easy right now And boom like that. It's wrapped in great roll So let's see if we can get this Back into position I know I brought it out through the bottom, but Let's see if we can bring it through the top It does have insulation on that side of it so that we should seal it Well heaters kind of nice So you just got to be like the factory not care and just grab right a hole that bad boy and just yank We got our wires up back up there Here's taken so far been hustling, but it's definitely it's not been I've been sleeping either that's away from the drop motors shouldn't catch on fire Okay, he's hooked up So I know the blue went right there The gray one there had two martens on it and that one there's pretty obvious But it's a small a little spade terminal. So you can't hardly do that one wrong Yeah, okay A couple more screws we can kick this turd on see if she makes it smoke So what I'm going to do is run this thing with this door off So we're sucking the fresh air in to help dilute Any smell that that's going to put off I've got the gas on got to go inside warn them and let them know that That's going to possibly go off. So I went ahead and cut it apart. You can see how thin that is on the corners but Here to look at what the other company missed This didn't just happen in six months after they checked it now It's been going on for a while and they hadn't been looking They've been checking it and they completely ignored it I mean you could see the the thing like I said the turbulence that were broke That's something you guys got to make sure you're checking Otherwise you're gonna have things like this happen make you look bad. All right, you can smell the oil and stuff But it's not too bad Go ahead and turn that back down just a touch It's a pretty good size building and stuff. So it's Didn't create too much of an issue. Let's go on back outside Make sure everything's burning. Okay, and what's surprising is this one here really doesn't have that many problems Refrigerant was fine. Like I said the little baffle thing was screwed up in there, but She seems like she's running. She are roaring. Yeah You gotta get that back in there Smells delightful All right, well Coil ain't leaking. That's a good thing Not feeling any disturbances. No real air leakage. I don't see any I got that sealed back up there And uh I think we're good So if I add that extra fresh air from the outside, I think I helped to loot it out because I could smell the the familiar oil smell but Yeah, no problems though. That's good You can see that blower All right, one last thing to do before we get blown away here I'll just Loot back in here Alrighty, it's all tucked up in there and back to where it should be. So we're gonna go there Go ahead and just door on and drop the stat back down All right, so we got the air y'all cleaned up blew it all out. Everything's good to go. Everything's back to the way it was That's for the people that don't know how to drive their lawnmower They tend to cut corners and run over stuff. Well, if you guys enjoyed the video and you want to see more like it You know what to do until next time guys. We'll catch you on the next one later
