 They said they were having problems with the furnace and of course they told me this after I turned the power off of it. We are on a no-heat call here and it's for the lobby area. So they said they were having problems with the furnace and of course they told me this after I turned the power off of it. I was here to do a filter change and do the PM so there was probably a code there didn't know about it but because the fans was running it's kind of hard to pull these filters out of there and over here on the ductwork. It just turned it back on and of course the draft motor is kicking on. I'm going to see if we got something going on here or if it's something stupid like an igniter or a flame sensor or what but I thought we had just gone through this thing not too long ago. 31, can't remember, is that a pressure switch? Pressure switch. A lot of surprise. Alright let's verify that that truly is the issue and see if we got a trap issue or what's going on. I went ahead and just checked across the switch and it is open so we did verify that. Let's go ahead and check some obvious crap. Let's see if Aaron takes got an issue so let's pull this cover off and see if it changes its tune. Okay I took the cover off and it immediately started. What a surprise. The pipes go up through the ceiling there. Amazing it left that open. Usually you put this cover on and off. You can, oh wow, that thing's really pulling on that hard. Yeah we've got a restriction of some sort in there. Could be, this does not flex a whole lot. Old three inch pipe don't move a whole lot. Go outside, we might be able to blow through this thing. Vacuum it out hard to say. Now if this was after hours and or snows on the roof or whatever you could always pop off the side there of the other side of the box there because you can pull it in from the air from either side and have it get them going or you know I wouldn't want to leave the cover off like I'm doing but something's in that pipe and that stuff that we got there's just remnants of probably what is probably in there so let's go and see if we can see something outside. From what I'm seeing here that looks like the old flue pipe for the old furnace and that black thing is either a vent for the plumbing or it's the vent for the furnace. Well lucky here. There it is. There it is. So at least it's three inches all the way up and out. I would speculate we should be able to blow anything in there that's in there out of there. Might even be able to run a fish tape through it and lucky there there's evidence all over the place like I always say you got to build the case. See that right there? That's the bird's nest. So the birds are living here like a bunch of freeloaders. Let's see if we can get that blown out. I've got my little Milwaukee tool. Let's see if it'll work. It's three inch diameter is pretty big so it may not do much. We just tried blowing through there stuck it in there wrap your hand around it. Let's see if anything came out. Chances are probably didn't do anything. I don't know if that was there or not. Some fluffy stuff so I don't know if that's it or not. It's got to go inside and check and see if it works now. I'm gonna run some fish tape through there. I've got just about as much as I can get in there but they've been such a big diameter pipe. It tends to want to bend and stuff and not get all the way in there but I'm hitting against something so I've gotten at least all the way up. I would suspect into the attic at least. I don't see the end of it up there. Let's go ahead and put it back together and see if the thing runs. I don't want to start chopping pipes apart because I don't have three inch couplings on my truck or out of town again. So there's hardly anything up here to get parts. Shut her off and make her start over and see how it goes. It's starting back over again. It's still feeling out. We could put the vacuum cleaner on the other side. That's a funny feeling. I can't remember if that plate there was removed last year. See there? It just came on. But you can't trust that because the unit is warm now. It's warm. It tends to fire off a lot easier. Alright, so the pipe's clear all the way down there on the exhaust to the first elbow and you can feel we got really good air on that. Now remember we took that cap off the other side. They glued this on which really makes it hard to do much with it unless that paint's just holding. I'm going to smack it a few times. I thought about even just drilling a hole in there to see if we can look down through. I got my borescope. Actually you know what? Good golly. I forgot all about it. I got a borescope now that's like way longer than what I ever thought it would need to be. That right dear locks will make it a lot easier. We can look in there and see what's going on. So let's get that thing out. Let's go take a look. Now I gotta admit this cable is a floppy noodle trying to get that through that three inch pipe. So we've got a straight and a completely out first which kind of sucks because it takes a lot to do it after it's been wound up this long. And that's why I really don't like having, I think you're 16 foot here, something like that. So we'll go ahead and get that shoved through there. This has got like a set of camera on the side, camera on the front which comes in great. If you want to look inside the engine looking different multiple different spots and it's got a light on that one and light on this side and multiple on the front. Alright you can't hardly see it but we're on the edge of a coupling there. I'm looking at the front and the side view at the same time. So we're cleaning up to there. Let's go from the inside out. Alright so the end unscrews. We put a magnet on it or they get this hook. I'm having a hard time getting past these stupid fittings. I went ahead and drilled a hole in there and put a piece of tape over it because it's an air intake. It's not like there's gonna be any water in it. I'm trying to go up this. If I can get through it great if not we're just gonna leave off the cap off the end. This place is not going to care whether or not they're pulling the air out of the inside of the building or not. There's plenty of combustion air in here. You've got holes through the wall. You've got a chimney going past up into the outside. Say the least we're gonna see if this will work. We were able to get through. If you look there on the bottom screen that says F for front you can see daylight out there. Turn the lights off. See the daylight. Flip it to front only view. Just hold the camera button and there's the forward-facing one so there's full-size picture. Go a little bit further on down along just about all the ends. We know it's visually open. We can check the pressure switch with the dual monometer. Generally I don't have pressure switch to go back that often at least not the carrier anyhow. And a little hook thing really comes in handy if you need to hook a wire in the wall or whatever. The link is down in the description down below if you want to support the channel. Okay so we went ahead and hooked up the monometer to it. We were tied in on both sides here. We got our pressure switch. Reading on top is what we got on pressure port number one. Pressure number two is 1.5 and our differential is 1.78. I do not believe carrier was really bad about not putting their pressure switch ratings on there on the switch themselves. So it just kicked off and it's acting a little bit rough but it is doing it. Pretty good. Now as you can see once it's got running it's already started jumping up quite a bit. It's because that warm air is lighter and it's freezing through a little bit quicker. But that's the most accurate way to do it is to put it on both sides of the pressure switch. I'm sure you guys are in need of that. Now that at least I know that the pipe is visually open I would feel better bringing some air from inside here. Let's go ahead and pull this off. It's a 2008 so it's just a matter of time until it's good bad. The one I'm using here is the dual port pressure monometer and pressure switch tester which is the SDMN6. I'll have a link down below on that. Pill piece doesn't sponsor me or anything as of yet. This isn't a really good one. This has a vacuum pump actually in it so that you can test the pressure switch and then it has continuity checker across here. So if you wanted to know if that switch is opening and closing or if you have a adjustable one you can actually set it up with this thing. So it does a really good job on that. I went ahead and cleaned that up. It's got some white tape over that. It's like I said none. There ain't nothing coming through it. We're going to go ahead and clean up the flame sensor. Check the igniter's resistance. Cleaner constate trap out. We've already changed our filters. Check fan blades and motor ampurals. Electrical connections. Then we're going to do the walking coolers and stuff like that. So it's going to wrap this one up guys. The only other new toy I've got here is another Phoenix light which this one's pretty cool. It is also a head, head deal. I'll see if I can make a link on it. It's kind of cool. It'll tell you if the battery's good. It's got a total of five different settings. The lumens on it is 1300. My other one here is 1000. You can see the size of it which is just plain stupid. It's got a magnetic charger on the back and it's magnetic and then when you don't need it for that you can put it in your headset. Boom like that. We are on a no-heat call here and it's for the lobby area but you made it pretty easy to find which is kind of nice and we just got checking it over here and I've got a number three code which I'm not real sure what number three is. We're going to find out here in a second. It's an ICP Comfort Maker. Number three, pressure switch did not close or reopen. So that's what we got so far. So see whether or not we got a pressure switch problem or a draft motor problem. All these filters seem to be pretty dirty. Notice this one here. You can even get it out. Look a little shady. So that one don't look so good. This one here is packed nasty. These all get out and then these right here we're in there. Make a fair unit here. Heat recovery. Just pulled those out a second ago and they are just whistling Dixie. So we're gonna wash out those washable layers once we get the system back up and running. I went ahead and unhooked. Gee. Let's see if this thing kicks on here. Just finally came on. Draft motor is running. Hard to say. Looks like a pretty common simple vending system going on here. There we go. She gots the number three. All right let's go ahead and dig in a little deeper here. We got the filters washed out. Luckily they had a place out there. We could wash them out without having to get a hose out. So those are clean. Got her back in there. Yeah they don't have any filters so we're gonna have to get some. Let's go ahead and see what we got going on here. Generally what I'll do is clean my condensate trap out first and make sure all my ports here are clear. Seems to be clear. Got this one coming from there to here. I had some water in that one right there when I blew on it. It made the water noise. So with that being plugged up which probably means that that's not draining. Likely what's going on. I bet you we run it now. It'll probably run. And now when there goes to the draft motor right there. The one on the other side of the switch. Let's see what it does now. Well we're waiting on the other one. Let's see if we can get this one turned off. I don't know why I can't find the switch. You'd think they'd have a switch on there somewhere to make it easy but they don't. Guess that's as good of a switch as we get today. These filter racks these things are garbage. Total garbage. Yeah that's pretty bad. That still hasn't came on yet. Speed this up a touch. I ain't got all day to wait on this stupid thing. Oh there it goes finally. You can usually hear it girdling in that trap if there's any issue with the trap. Concentrate trap. Look at that. There it goes. This is why I don't usually film residential equipment even though it's in a commercial application because it's usually the same stupid crap. Dirty flame sensor plug condensate trap. Igniter bad blower motor out draft capacitor. Temperature rise ain't right. Not enough to return air. It's just the same stuff over and over. Just does not make for very good videos up when you're trying to get a filter out. You get a freaking spend six minutes trying to get it out without destroying it because you can't even use it. Problem the installers don't crimp down these sharp edges. You've got a sharp edge here that'll get caught on the edge of the filter and you got a sharp edge up on the top. So we're going to squeeze that down work our way across. I'll either use these or I'll use my channel lock slash you know whatever. But that generally will allow you to be able to pull the filter out next time. That way you're not tearing it all apart trying to get it in and out. Especially if you just want to check it. We've got that out of there unfortunately. Had to tear the bottom of it off to get it out. What we'll end up doing is brushing off the filters till he can get the new ones. I hate leaving them out because there's always a good chance they may not get around to it or they forget. Then you have nothing in there. Then it starts looking like it already looks in there which is not good on it either. Let's go ahead and shut down this other one here and get this condensate trap pulled out of there. That's about the only thing that generally keeps it from draining properly. They kind of they make it easy to get to that screw and they put the pipe right through here. It's not the greatest location for it. Looking at this trap it's got a little bit of crud in it but not really that bad. So I wonder we've got some drainage issues inside that collector box possibly. I usually like to see this hose kind of drain towards it more which if you make a trap like say I did it like that that actually make it worse. So it may shorten that hose up a little bit or possibly pull it back. Yeah I mean no matter what we could shorten that up a little bit and get a little bit better. Sorry I can't get you a good shot but we got this stupid thing right in there. It'd been a lot easier if we could have went out through the side and up but then you'd hit all that. So it cooled itself down. Let's go ahead and kill it here. Let's get that pulled out of there. What I find to be the best to get those clamps off is usually some wide lines like that with the crisscross pattern. Usually grabs right a hold of that no problem. Now they have a little port that you can see right there. It's on the other side too. See it right there. That'll be on the backside of this one. You can literally blow through the hose to see and you gotta be careful you don't want to blow the diaphragm out but you can hear it there. What that's supposed to do is break you know when it's pulling through this way it's supposed to pull anything that's in that hose out and back into the collector box so it doesn't plug up with crud which is kind of what it sounds like happened here. We can shorten that up a little bit. They leave these longer so that be able to move it around to different positions whether it be upflow, counterflow, whatever it is that it's being used for. But I don't know if that I mean it's been in for a little while. It's not like this just happened. Now you can see when you pull it through and lock them back into those pieces right there and there there's plenty of leftover here and you can see the hose can dangle down and see how that makes a trap. That's a lot of the issue a lot of times so let's kind of do it so they can't trap. So we need to take off about that much right there. I just trimmed that up. Let's push it on there. I don't want to cut it so short that you know you can't reach it or if you have to chop off a little piece later. But you can see we're not we're not pocketing now it's a nice solid slope coming down to it. I left it fairly tighter that way. You know you got extra up here and that's that's gonna hold in place there on that bracket that holds that. But that's pretty much all I think's wrong with this one. Now while we're here we're gonna go ahead and clean the flame sensor out and double check you know all the normal stuff I always check. Every heating call I clean the flame sensor, clean the constate trap, check the heat exchanger, make sure the flu pipes are properly pitched, you know make sure the fan blades are clean. If you know if I'm feeling frisky I might go ahead and check the capacitor on the motor if it's got one. You know it's just common things I do every call because you'll find a lot of stuff by just doing the normal things over and over. As much as I hate doing service checks and things like that I don't like callbacks. We don't get paid for our callbacks. You can see the nasty green crap on there. Now contrary to rip-off beliefs you can clean that. You don't have to replace it. I'm always been a big believer in the only way that things bad is if it got it so hot that it warped that metal or that porcelains broke. Otherwise you're just selling parts. So let's go ahead and get that cleaned up. I've said it a million times. I use my wire brush which is stainless steel. It's my preferred method and that's what I like to use. Use your dollar bill, rubbing alcohol, whatever else makes you happy but that's what I use. Here's what it looks like when we're done. I don't usually give me any crap about it but let's go ahead and look at the grooves if there is any grooves. You can see the cleaning marks but there's no deep grooves. You're gonna have some when it gets that hot because it's constantly in the path. Lennox always seemed to be the best about not getting damaged. Carrier is not too bad but boy there's some other brands out there just bake them and they just tend to overheat. I don't know if they're not using stainless steel or what they're using but some of those just tend to really get damaged really easy when they get too hot. But there's that. Let's finish cleaning up our trap here. I'm gonna go down and rinse this out in the sink. It really don't look that bad. I mean it looks like hell but far as any true gunk there really ain't nothing in there and there's no good way to get this clean. It was one problem with them doing it the way they did it that you can see the nasty crap. There's no way to really truly get it cleaned out very good. I mean you could put a Q-tip through there possibly but it ain't really doing anything. I truly believe most of our problem there is with that hose the way it was. As much as I hate to do it like that I mean it's about all you can do. I brushed them off a couple times and then smack them against the pole right there and the fluffy stuff just goes flying. It's good enough to get them by until they get one. Hopefully they'll get it within a few days to no more than a week but that'd be good until then. We got that all shook out and just looking Jim dandy. Still looks like crap on the inside but like I said anything that was loose has been rinsed out. Let's go back in and get this crap in. To put the side it actually has the piece on it on in there. So that's back up and gone got that one back in there. Let's go ahead and check this capacitor out make sure it's okay. It looks like it's rated for 35 which is a hog doggie. Let's see if we can get on that while it's in place. 35 so we're looking good there on that. No issues. This thing's only I think a couple years old looks like 17 2017 and looks like it started up 10 1 of 18 so 19 2021 three years old is all this is. Now do what you want but whatever I work on these especially in a counter flow like this I take them all to their maximum run time. Now this fan runs all the time on this but what happens is if there's any residual heat in there it'll come up to here and on these furnaces they do not have a limit but on the Linux's they had limits on the blowers they had you know all different limit switches and they would trip. It's a good thing to kind of remember and to do it can prevent a future call-back but this one here the only limits they've got on it is the primary there in the center and some rollouts there and there so we only got two rollouts. I've had some where they've got two in the front one on the top one on the side one on the side they're just rolling out and they must have been singing the song that day when they were putting them in. This is one of those times where that long extendable head is able to get into those nice tight spots that aren't ideally placed you can see we're at an angle there works out great because you can push her right back the way she was and she's a normal screwdriver again. All my tools that I use are down in the description underneath my kit anything you guys buy helps support the channel it goes to my Amazon account you guys still pay the same money but I get a couple pennies on each one of them so there you go there's that got that back on got to hook this green thing back here on top of the trap itself there we go and that goes up there to the top there we know that's clean and clear let's go ahead and start over which I hooked the G back up so the fan's gonna run let's see if she kicks on just revved up make sure that gas fells back on that's why you always cycle this thing last thing before you leave that way if you got anything turned off you're not to forget and run it so we're good on that we pretty much went through everything you need to check I mean the floor capacitor is not bad we've got the collector box blown out we found the water in there which is great because it gave us the right lead of where we're at we're not just guessing that that's what it was because as soon as we heard that we knew that that was blocking off the pressure switch suddenly do I have a bad pressure switch on the carriers it does happen so we're good on that went ahead and got their fresh air make up there taking care of and cleaned up that wasn't part of the deal but you're here you might as well just give them a little extra for their money same thing with this unit over here got the filter cleaned which I would have preferred to see it replaced but they don't have any here and we don't carry them on the truck which it looks like they've been doing says they're not the brand filters we use that's gonna wrap this one up guys I'll go and contact this on possibly with another video if you enjoyed it you want to see more like it make sure you hit the like button subscribe and check us out on Instagram and Facebook and until next time we will catch you on the next one
