 So we're on a commercial call here air conditioner wasn't working right This weekend they found it in the wrong mode Turned it on it ran and now it's not working again Lookin in there. It looks like we've got frozen evaporator Coil we can't tell quite yet. So let's check the obvious stuff and see all our filters and fan and stuff like that is We took off this armor plate here and the filter looks a little bit bad If we can get it out of there That thing is oh, it's stuck to the coil The coil is pretty jacked to the max Well, I can feel the fan run and that was one of the things I wanted to check first I would say when you have ice on the outside of the unit, it's probably not a good thing Definitely not a good sign seeing was brand new in 1998 It's not sure going to be able to get a whole lot of water up here very easily But that would be the fastest and easiest way. We have to pop this top off of it. See what we can do here So that's not looking good We're just slightly iced over here a little bit that Makes a nice ice machine your fan blades here just touch dirty. Yeah, she's uh Feels like the bearings feel good though. She gets a nice smooth turn left and right So it's gonna take a little more than just a little bit of heat. That's been going on for a little while there Yep, well got to get their maintenance Department and see if they want me to melt it out if they want to just let it go and come back later Or what they want to do because that's not gonna come off with just a little bit of heat from a torch So we had a rope our hose up to there And I've got another hose over there that I was able to get from inside It's not hot water, but it'll at least get us over to there where we can melt that ice Some's better than none and it'll also allow us to work out the coils that I guarantee you probably dirty And it almost reached so oh Well get 75 extra feet here just in case you know Probably be about I did a put a trap on that Might help it Yeah, this is probably gonna make a mess I don't know where those holes came from So I ended up doing is there was some holes along the bottom I taped those up built me a little ramp which ain't working for crap and this ain't this ain't going very well So one thing as I went ahead and decided I'm just gonna go ahead and wash this coil out And then we'll just come back and then I noticed the reversing valve So I'm gonna force it to heat that coil up that should speed it up I'm gonna do that after I get in worship is condenser out which no matter what we kind of Are in the good here because you can see how bad that Nasty crap is coming out of this coil. So it We're gonna make good use of this hose being up here You can tell this doesn't happen very often. That's That's a nice chocolate milk right there Trying out my new soaker hose here too Kind of see how well this works out using this for special occasions where you know, you want that fine mist so We'll see how it goes. It's not the real long wand. It usually is a pain in the butt to get into places So we'll try this out see how it goes and get this thing cleaned up and then we'll see if we can get this thing running in Reverse mode there and melt that ice off. Hopefully we can pull that blower out too. That's a total wreck So we've got it running in heat mode I can feel the heat You see some of it's starting to melt it's gonna be a while for that right there I've got The coil washed out a lot better than what it was And it's not washed it's washed Washed out so we're gonna watch it for a little bit and see Hopefully we can maybe get this stupid filter out of here, which is I think a good majority of our problem But I mean it's still frozen there literally so It's just a waiting game now A lot of wasted time, but we really don't need to be coming back So we went ahead and dug some ice out and it melted it out pretty decent We're uh got a small little piece back here. I gotta get out yet But we got mostly crap out We're still going to pop this top because there's so much garbage inside there and there's probably a lot of ice on the back side yet That's just one of them Freaking mess as you can see the crud Yeah, it still hasn't let go there yet. I just packed right inside there pretty good Didn't enjoying these new gloves they got gave us the we had some similar They're kind of rubberized on one side they're stretchy and they seem to be kind of cut resistant to a point filters plug solid Coils that got so still the coil still has ice So we're getting that out of there See if we can't get that blower out of there worse it out while we've got everything apart. It's just a a wreck We'll see what we can do with this if we can Get her back out and go on here Okay, so this crap here This is stuff that's floating around. This is like a plastic factory So i'm digging this out Of the coil. It's uh deep up in here So i'm getting up in these cracks and crevices here And dragging it towards the front Because water just will wash it deeper into the coil So we're kind of just dragging it forward getting into oh boy. I can feel it there Yeah, you just bring that forward. Yeah, we're gunk so we're washing it and Getting that crud out of there and then we're rinsing all this out too I ended up just kind of smacking it with the back side of my wrench had to be careful Otherwise you puncture coil, you know, it's one of the things where it's uh, We got a lot of work to do and we ain't got a lot of time to do it And not a lot of people to do it. So make a mobile trip back an hour one day. It's just a lot of wasted time So unfortunately, it's just quicker in the wrong long run here to just sit here and Work at it and get her out of there as best as possible See if I can get you a Shot there with a light on because this freakin sunshine out here is actually Pretty bad So combine that with a nasty filter And that's what you got. So that and a dirty fan blade. So airflow big issue Wouldn't be surprised. It might be a little low hard to say I haven't got to that point yet. So we're still digging lots of digging. I was able to yank the blower motor outside ways I'm going to rinse this all out. I'm going to do as little unhooking as possible. I've washed With motors in there forever. I don't recommend using a cleaner in there Work your way slow sheet from the bottom down. So don't let it spin because if you do it'll get in the motor You do it however you want if you want to take all the time to yank it out and all that you do What you want to do if you're a rookie Tear it wall apart spend an extra 15 minutes 20 minutes on it And putting away taking apart putting it back together that way you don't ruin anything, but I uh, that's not how I do it. I try to speed it up however I can Man that is nasty crap Jeez A lot of it either you can see You don't want it to spin if you do it's going to leap around And fall down on the motor you'll get a little splash on the motor. It's not going to hurt in it We're getting it out of there. At least we're doing it. So we've got it cleaned out Coils look a lot better than what it did. That is a wonderful trip hazard to get there Coils look much much better than what they did I've got the condenser coil much better than it was Lower wheel actually can somewhat breathe now re-tape my nuts here that were half ass Tata See, I hate people that don't know how to strip a wire They make it nice and short and don't get caught in a wire nut. Don't be one of those people Make the thing long enough. It actually fits in the nut So we're going to re-strip that Give it something to tie on to I gotta admit I really like this head it swivels 180 back and forth variable And multiple different spray patterns. You see the crap that they must have a pan underneath this thing or something I ain't ever seen that before But I've got down in between here since we have the top off now because I couldn't get through the front The silicone to all the front here it uh Got all down in that coil Big time better than what it was I can see light through the coil like it ain't nothing Through over here. There you go. See left to right? There you go So they didn't even have to use the uh chemical on it because it's really one pass thick One and a half passes if you may be lucky pretty thin coil only nice thing about the 10 seer units And uh, so we're gonna get this thing back together get the trap on it And uh get the charge checked and we'll see if they got a filter for it because I don't carry any on my truck But otherwise we're looking pretty good in the hood. I got checking the pressures and they're a little low We're about 60 degrees 61 degrees out here And we're running about a 25 degree Uh evap and about an 80 degree Condenser so we're about 20 over ambient. This one has a tendency to run 25 to 30 ish area Either way we're low. We got a fan cycle switch. We're gonna put on here But since this is a heat pump, we've got to put a relay on it to bypass the fan control When it's in heating mode, otherwise the fan's not going to run and you're gonna have issues So we're gonna wire up a relay off of the b terminal Because these guys use the b terminal. So we'll just have to power it so that it bypasses it. So nice thing is We've got a Straighter port down here on the high side. We're gonna tap into that drill a hole through that firewall there I just now noticed That is trapped external or internally. That's great after I just put that trap on it great Super duper. So that was a waste So I got that on there while I take that off the double trap will be an issue Whatever good thing we caught it. Otherwise it wouldn't have drained for crap double trap don't work, right? So we don't make another mistake like I did on the trap got looking here They have a low ambient relay is what I'm assuming the stands for IOPT optional So they are actually breaking the black wire there and then it's powered Based off the black wire there Off of brown. It says down here. See uh, that's awesome Gotta love the wind wind is awesome lots of wind so optional three Just waiting for that to come knock my skull off next Uh It says and seen note or the heck said that I seen the note thing somewhere in your note note three So down here If low ambient control Is not used connect black wire from the outdoor fan motor to wire nut from dr, which I love all these abbreviations dr you would have Be frost relay So chances are it probably does not have that however. I've seen a couple of relays in here Looks like a fan relay here. That's what I'm assuming is There's a green wire looks like it goes down to there. So this is your blower And I was pretty sure this right here is all defrost control. So it does not have one for that so we're going to Intercept that fan Up in here. So we'll get that here in a second Found it. Here's where they Have the black common wire coming up to the defrost relay, which they're using that relay to break it when they Go into a defrost So we're just going to go in interceptor right here with this one And we will power it shut when it's in heating mode We'll be good to go. It'll be normally open otherwise based off of it'll be basically across the contacts of this here It'll be Normally open letting that do the closing and when it's powered when it's running in heat mode It'll power the shut jumping that and bypassing it simple So we got that in place there went ahead and got that wire tied up because that wire was dangling there on that 3 eighths line out of that filter dryer We're going to sleeve that copper line going through there And finish mounting things up Here's what we got so far. So we got the control mounted here Curly curled up going through the hole got to get the sleeve on that yet I've got the fan wire coming in going out and I have it in parallel with a red set of wires Which all this stuff here is rounded edges. So that's why there's no romex connectors comes up to the normally opens contacts here I have b going to one side of my coil the other side of common going to the common terminal strip here And that's about it. I went ahead and checked the schematic to find out which one was b which was black which turned into gray And up it goes to there. You can kind of follow it from here, which was all in the Schematic which is right up here pretty brain dead and simple which worked out good because Up to there it goes And uh, so now it's just a matter of getting it turned on and we're going to get the charge set And then we'll set the fan cycle first or after we get the charge set I ended up cutting that trap off That's going to at least get it away. So it ain't draining down the face of it like it was doing Whether or not that makes a big difference or not. I'm not really sure but At least it's on there and makes some use of the pvc plastic So we got it finally tuned in tested and it's running. It's cycling the fan on and off Frasiers look pretty good added a little bit to it. I got to weight reweight my bottle Last thing I want to do is bring weight skill up here with all the other crap. So It's going to wrap this one up. I've got to get my caps on there If you guys like it, you know what to do until next time guys catch you on the next one
