 This is kind of interesting. I can now see what it couldn't see before There's the drain pan and where it's broke it. I don't know how this happened All right, so we have us a water furnace here. I found a leak the other day down there on the valve well as I'm here for a water leak and we have got Water leaking from somewhere in this pan It's it is leaking on the pan though and the drain line is clear Any new pan and it's got an issue and that coil Does not come out With the pan in the place I'm looking really closely at the back there now that I've got a lot of water in there because it wasn't running in air condition before And the coil has oil on it, but when you get right over in here Until there's something there It'll get faster in a minute Here's it somewhere in this area right here And it could be like Three rows over going in the back side and you got a little bit better hit on it All right, so we are in super mode we are Showing off the infocon stratus Problem is it's just a such a small leak That's where that dents that dents right here That I had from the H10 I go slow. It's almost worse If I go a little quicker, it seems like it picks up better. There we go Fingers are off of any buttons. Just so you know, there's a button a vent on the back You got make sure you don't put your finger on it but there is It's picking up a little something up here in this top that I wasn't getting with the deep or the H10 Yeah, it's got something right there. It don't like It's going full board now out of curiosity. Let's go ahead and put this thing into the parts for million mode This is not as sensitive. It's really made more for narrowing it down in contaminated rooms The lucky there This way a little bit. I'm gonna sway a little more. I think I go back forward a little bit Now you tell me that ain't precision boom, baby. I Am happy hamper and now granted you got to remember that was doing it Really taking your time So I mean if you got once again, I seen oil there and that's the reason why I stopped Each 10 is a great detector But these these people like to hate and say that it's the only good one out there I'm sorry, but you've seen how hard of a time I had finding it with the H10 And I'll see when I scan for leaks the first time I scanned over here I did not scan the other side of the coil But I am hitting something over here. Just did you know, but if I was going like this Well, hell I even hit it that way. Yeah, look at that. I Don't know for some reason it seems to be doing a lot better today than it did that the other day original reason for the call on here was the water on the floor and I found a leak down below here right beside the reversing valve on the little tube that goes to the Ends of the reversing valve that pushes the slide one side or the other so I fixed it on that figured Well, it was low on refrigerant the system ran a lot And that made the loop get colder and colder and thought it was sweating through here because you can see the insulation on there It's pretty wicked It's kind of wore out and figured it was from that because if you look at how it is It's trailing looks very much like it's coming from the geothermal, but unfortunately this time when I did it I went ahead and Ran some water in a pan. Even though I flushed it before This time as I ran a continuous flow of water in there with a garden hose and a And an attachment I was able to get water to come out from underneath that pan So since we're going to need to replace the pan now technically we should replace the coil We'll get both things done at the same time. Yeah, you're right We better do the detect three to prove that it is just as good as the stratus in the h10. Here we go It's actually doing better than the stratus, especially when you know where to look Knowing where it looks half the battle So there's that side There you go Don't be hating Check her out if the con detect three get you on To replace the evaporator on this water furnace They've got all the screws taken out the coil around the edges All around three there We're finishing up a recovery we're using our Bob core depressor tools there to speed up the recovery which they will recover this whole system and Under nine minutes looks any bad We're going to go ahead and get these electric strips probably moved out of the way And we got to get this evaporator out of here power is off We're going to have to feed these strips. So you definitely wouldn't want to forget that You might be able to get This out without having to yeah, I think we're gonna still have to pull the blower Been a while since I've done this As you can see the strips are kind of a pain in the butt They've this is a poor design had quite a few of them Burn off the back there. They use that molex plug. This was horrible design See what I had to redo this crimp on there on the wires is all burned off once already It's just hook in the back back here in the back. I get little edges there and Some three eighths in the bolts in the front. It just falls right down Praise them hook that be that all the way be a lot easier All right, our new coil here's aluminum. So it shouldn't be damaged by these Things that are floating in the air. All right. We got that cleaned up use the wire brush wheel and got that Frickin foam tape off there. We went ahead and cut out a patch in the insulation so that we can Sweat that out without burning it Then we'll glue it back into place Right now with purging nitrogen through To clear out any residual Refrigerant that might have been left in there and get to all the oxygen out. So I ended up unbrazing the suction line first because a nitrogen was purging through the high side and Then did the high side last so that's undone coil is loose and Looks like we might be able to pull this thing out possibly. Okay, we're gonna go ahead and lean this down Pull that loose Should be a little more room To lay the coil sideways And to pull it out There's no good place to mount the camera. So you're just gonna have to deal with the fact that I can't report it I'll do it. This is only like the probably the 15th one I've done. So it's pretty pretty common Machine is older, but You guys that don't know what geothermal is or haven't priced one. You'd know why they would just go with the coil This is a 410 a unit and everything else in pretty good shape This is kind of interesting. I can now see what it couldn't see before There's the drain pan and where it's broke at. I don't know how this happened but That's snapped off from the side there And broke at the back so you can see the oil It's definitely been leaking. That's not just water Slide that turd right back in there Nice and simple. Just make this baby go right in there One two three go. So there was not a Miniscule amount extra to work with you had to have that absolutely dead perfect right up against the frame and Talked very very nice to it. Wasn't fun, but I was able to get those screws in there in there and There Then kind of nice if they would have gave me the exact size So this right here is half inch and this is 3 8 7 8 3 quarter So we're gonna have to sleeve this thing to make it fit in there correctly but it appears it's the right coil and everything so Just must been one coil can do more than one thing. I suspect I have no idea not an engineer Don't play one even on YouTube So we're going to get that sleeve and get that on I Went ahead and went out there and did me up the fitting So I went from half inch. I had a swedged the softer copper looking side because When I swedged the factory side there it split So I've got a piece of three quarter there or seven eighths. I should say we're sleeve right into it It's all cleaned Couldn't burn us in got the torch running just purged it now. We're running on braze mode I was able to get all the way around the back side without burning the crap out of that metal Which is why I had to cut that a little bit wider again because that coupling pushed me over but Inspector with mirror and everything's good to go get good penetration all the way around So we need to put this filter dryer in which they sent with the coil So that's where they hit it at and it's in the best of play the best places to find it So we got to get the sensor off there and get this wicked nasty Crap off. I was able to suck the solder into the TXV on This one side here as you can see there's no real good room in there But it pulled in there to it there's such a goober on it from whoever did it originally Which I assume might be the factory Because that dryer that was on there looked kind of original. It was really rusted We were able to just use what's on there because you couldn't really put the dryer into place and Add rod and make sure it don't spring off and everything else at the same time So that definitely is not going to hurt having a newer one on there all right, so she's getting Vacuated I'm gonna go ahead while we're doing that Or I go ahead and get this all insulated got the electrical back in there Tighten these up real good along with the straight heads How to put a few more crimp on's on there that was broke off got the ground hook back up Just got to get the blower in there You cannot put that blower in there thin and then turn it sideways like it needs to go You literally have to put it in sideways or you've been the fins up on your coil there for the blower here Now what's kind of interesting is you've got the speed control here You also have a speed control back here in the back. This one in the back Comes up to an Intelli zone Controller, so what worries me is if I was to hook it up. They might have issues That don't look kosher I don't know if there's a reason why they have it unhooked if there was a problem with that zone board No one's marked it and said so Unfortunately, we're just gonna hook it back up the way it's been because it's been working that way Gotta get a new ground log on there all right, so he was able to Get that ground wire there on the log No, thanks to this Mess of wiring in the way, but we got it on there got it down there and it's in place nice and tight Got thinking about it with that being isolated with rubber feet and 50-50 chance of the copper touching Chassis somewhere for ground and the aluminum being the softest metal in here Chances are if that compressor shorts to ground they were afraid that maybe the place where it would ground at Would be through the coil and it blow a chunk out and then you blow the refrigerant all out It's going to go to the shortest path of resistance Which is straight down there at the feet So we've done the valve off test a couple times. It's gone down to as low as 400 area But keep rising which the oil has refrigerant in it Probably has a little bit of moisture, which is whole reason for the filter dryer So we've got that in there. We're going to valve off get this thing charged up and make sure it runs Let the filter dryer do its job. We got her palved off got to purge our hoses here a little bit residue blown in the air That way you can breathe it Sure doesn't cause cancer or anything. We used our valve core tools along with the valve core depressor tool To speed it up because I don't have it about a max tool. That's like stupid moronic prices that I will not pay For I love tools, but I'm not spent four hundred and some dollars from some homemade looking tool So I've got the power on it and my thermostat was dead So I had to go check in here the plug that we plug into the back there is exactly the same plug They used on the blower motor to power it they both come from up here in the distribution block I got this backwards. So if you ever have a time where you do some work and you have no control voltage Check that plug. It's easy to do it backwards These are all kind of as you can see a fluster mess of wiring. All right, so my thermostats up there blinking like a madman Come down to the zone panel. It's got a fault. It's never just as easy as changing a coil It always turns into more which is why I always put a little extra time So it never fails. This is what ends up happening and you know This is uh I can tell you right now. It's an ecw board. There's no way this is you know, water furnace didn't make their own We held the reset button for quite a while And it erased it So in one and two which is only two zones is calling Got a cooling call Right there goes my compressor. I think There goes the water circulators for the loops There goes the compressor Since that is probably powered off the unit and this only powers the damper motors, which is a possibility Not sure Nope, there goes the flip and fault again You know, the only thing it could be is ecm motor. Maybe that does need hooked up. Maybe it was hooked up I don't I don't remember I'm pretty doggone. Sure. It was slain in the back. So let's go ahead and hook it up Here I got that out. Let's go ahead and hook this thing up. See what happens See if it controls it It might have been wire tied up in there. Like I said, it's a big old freaking mess Blower runs and it controls it great I'd rather have this decide that the fan needs to speed up and slow down When it's in first stage second stage opening two zone dampers versus one. I mean it would make more sense This is kind of a surprising that it has that built into it I've never seen a zone damper board that controls the blower motor like that First one from me I'm used to carrier communicating and just regular Uh, ecw style blower just came on. So that controller must work For about freezing. So that's a good thing so far. We're still running if you look right there Speed five, which is kind of kick butt We are running Y1 Y2 on both zones And that's calling them both things so Let's say we probably were having an issue with it reading the thing that uh, I wasn't paying close enough attention obviously. So that was my fault Luckily it wouldn't hurt anything by you know Not feeding it from that particular one. I mean I hook it back the way the factory had it originally so It appears to me when you're on the Right track now. There's no duct sensors on this thing to tell it whether or not it's getting too cold Okay, so we were 74.6 on the one on the return And we are running about 52 there. So 62 72 Uh, that's 22 degrees 23 degrees area And in the past we were running about 20 degrees uh, so it's Right in line with what it's done in the past That's what I had back in july of 2018 And I repaired it reversing valve high side pressure tube recharged with new refrigerant And then today we have the coil which I found when I came back because it was still leaking water Because the dream pan was um bad. So the dream pan was bad We ended up, uh, I ended up, uh Noticing the oil and the coil this time again I noticed the first time scanned it, but I scanned it rather quickly. Didn't see nothing This time I checked it a little more carefully. I hit it with the h10 first Got the leak just barely hit it with the stratus got it got it with detech 3 Condemned it as you can see the coil has streaks in it Um got them a quote on a new one. This one's got the aluminum coil. This is obviously country water So they do have a touch of sulfur, which is the reason why they have uh cpbc plastic pipes Instead of copper Plus just the age of the house. They don't have packs. Otherwise they'd be at packs and um So otherwise we're uh We're running pretty good. Everything looks fine. I'm going to run it in reverse Here so that way I know that my txv is feeding correctly in both directions So let's go ahead and do that real quick That's why I like testing it in cooling mode first. I will Just rip off one of the leads for the reversing valve like that And we will make sure the pressures are reasonable And if so, we are good to go um We blew off the drain line here real good. Um Got everything insulated back up back here in the back. We got that all wrapped up um I do want to scan that one Joint back here just to be certain. I mean I sprayed it for bubbles, but I didn't like not being able to add a brazeron to it, but To be able to hold it and do everything it wants just it's not very Easy So in heat mode we're not extremely one way or the other Which is good. I'm happy with that Go ahead and flip it back to cooling And by doing that we don't have to fool around with the thermostat delays and all that garbage Just makes it so much simpler This does have a super heater loop that goes up and over to the water heater And uh, basically it's free hot water or when they're in, uh, whatever mode if there's an abundance of it Make sure we don't have anything vibrating And all of our tubes are good Go ahead and dump what we have back into the system And get out of here All right guys, that's going to wrap this one up Make sure you check out the facebook group and instagram if you would you enjoy these I like to see thumbs up. So if you would hit the thumbs up if you didn't Hit a thumbs down. It doesn't make a difference to the channel It just hurts my pride. So other than that until next time people we will catch you on the next one
