 This video is brought to you in part by TrueTech Tools quality tools essential support All right guys, here's what I'm working on so This is a paint booth and it's make up air unit what I end up doing is I replaced the regulator here in the Silinoid added a tee down here, so we could check pressure Checked my differential had some problems with the pressure switches. I was kind of all screwed up This is an older one spray tech gave me the name and phone number of a guy He told me one of the things I really needed to know because it's what's going on as a pilot would not light every time It seems like it's a pilot issue this bleemove out here was Flipped the other way, so when it's in a bake cycle, they actually want it like this and In spray cycle, they want it open. We're flipping it around. I'm hoping we're doing it the right way from the way It was described to me and this guy. That's all he does. We're gonna try this see how it runs Now this basically changes like that And he's saying that it was reversed only other thing we could have been wrong was our UV bulb there That's how it senses that it has a flame or not. He said Stare into it. See if you see flickering, which I did not see any flickering So here's the pilot. So we're gonna go ahead put this back. I think What we had going on is our dampers are in the wrong spot. That's our issue So I got that back there. I want to get too tight on that. I've cleaned the pilot out I've done everything. I'm under the sun. I've adjusted the electrodes There's a little bit of a crack here on that but cleaned all the main burners there out did a little bit of everything That's the the fight that I've got going on right now right there is the blower big old monster old-fashioned blower No VFD none of that stuff. He's like man, don't have VFD. I'm like, no not at all dude Super nice guy though. He actually works on these and He took the time to talk to me I Could use a little little oil in so I flipped that around which hopefully it stays there until it goes into the spray Which then supposedly will open up. We've got an issue with it not firing every time Kick that on Honeywell's coming on Okay, we're gonna turn on Turn on the heat so it should light up. I hope Let's go see what the what the dampers are doing. Bake is on and off here when you flip one bake that brings the dampers to that to the vertical position Let's see where it goes. We're locked out Go ahead and reset it see if I can get over here to the pilot see what the dampers are at see if they're backwards That's opposite of what we want So maybe it was right darn it. I was hoping it was wrong My interior is a pilot and it just alarmed out I've checked my spark there. It's working fine Like I said, we just replaced the solenoid here. I thought maybe it was sticking to make sure my regulator was replaced God, maybe it wasn't doing its thing So there just took a dump. All right, so I put it in bake mode See where these Dampers are going in bake mode. It's opening up. So yeah, it was right the other way it was right So we got to change that back Can't get your fingers on that either There so I so much you can do with this stupid thing I mean, it's got a good spark to it Porcelain's not cracked look right there. That's all Perfectly clean. I think I already done taking this apart if I remember correctly taking us all apart You start second-guessing yourself because you really don't know where else to go with it I mean, this is the guy that that's all he does disease. So what else you do? Yeah, I'm 99% sure I took all this crap apart Yeah, it's completely open down here on the bottom. I seen this little square thing The square thing was this little thing right here They're all the way across there. They have loosened up on all of these So I am going through and tighten your knees up. Look at this one right here That one of these completely fell off the bottom. Well, that's what's holding that plate in there And I can't but I wonder I'm hoping That was allowing air to sneak underneath of it and through it causing a disturbance on my pilot. Otherwise all this here looks Fairly, okay. I mean, there's a little bit of roughness to it, but things 22 years old Let's see if we can make this thing run. So we got that back on I'm gonna turn that bake off and see if we can get it to Just light normal Well, I guess we'll just let we'll just see what happens first Look at that instantly pilot. No problem at all Make a start over again Pilot perfect every time It's better than what it was doing. I'll just turn the main off here Beautiful Took a little longer that time Now what I did on that igniter spark box down here. I Used a screwdriver Grounded it brought it to it pulled it away. He's insulated screwdriver and all that happy stuff No, no issues with that. Hope to goodness. That's what it freaking is Let's go see whether it's in bake or what's going on It's got that front displays on there we go See it sort of it's lighting. So in the bake position, it's kind of closed down Okay, let's turn bake off See how the pressure started to drop Let's go ahead and hit Reset let it start over again This is in a traditional mode that was started and boom instantly. Yeah, I'm gonna hit reset and run over to the other side See if I can see what that does Yeah, it was already lit up. It's good and turn it on Let her eat See how she does so there you go You can see the main burner May have just finally gotten it. Oh my goodness. That's a stupid plate That little dinky plate thing. All right. It's still kicking on every time perfect guys I think we finally got it. Holy crap I would just I that that thing was way in the back. It was dark. You can't see Main burners and stuff look good. Yeah, we're gonna go ahead wrap this thing up guys What the hell is things I can stupid that's gonna get it for now, I guess As you can see, we just got all kinds of different things going on today We'll just record little things that we do through the week and if nothing happens You can see what the heck I'm doing. We do all kinds of odds and ends stuff I mean, it's not always HVAC. I mean just make a bear, but it's a freaking paint booth You know, it just what it is my work on demon to fire Air dryer for air compressor, whatever a little everything So anyhow on to the next one guys All right guys, so we're working on this beater chiller from 1999 area and this thing has lived a hard life We've got two compressors that are bad ones locked up one shorted We lost some of the controls here on the board That got wex somebody didn't get the door secured. This is 480. So I've got everything killed I've verified all powers off. I've been doing some tracking. I haven't done many of these I had to figure out how train does all their goofy Terminal blocks and stuff and it's not bad once you know what you're looking for So we found out where everything's at all said and done We have a circuit here where we've got all the safeties for the compressor coming from this terminal block here Going to this terminal block over here and the way we figured that out and through a fuse Codes through a pressure switch a temperature switch temperature switch Auxiliary contacts which are on the back of that breaker and eventually gets over here to terminal block 7 Which then feeds into these inputs on the board So when we ended up jumping the terminal block out Eliminating all those things that should have locked the compressor out. It still did it What we were getting was compressor trip and see there's terminals back of the breakers there If you turn us off that breaks the contact on the back It's just like a auxiliary switches on a contactor the board obviously looks like it got wet So it looks like we got some damage there. We jumped it. It's still locked out all sudden done What we come down to is the board is bad. We've already got two compressors out We got a condenser coil that's leaking the thing is our 22 it needs replaced, but it just hasn't happened yet All right, so what we're doing here and you're gonna laugh But I don't have a whole lot of options. You ain't gonna pick this board up at Walmart So what I've done is I've went through already and Taking a plug like this Marked where the relays are at which one they're going to and we were actually cutting them out So you see I've already done that on these here. This is circuit two. This is circuit one What we're gonna do because right now what we had to do and the maintenance guys did is before I got here because it Bypasses all the safeties but they needed the machinery to run because they can't run the presses in there So they ran it off this contact over here There's no safety controls when you do it like that this compressors, okay But it's low on charge compressor on circuit two is okay It was locking out because there's thought there was a failure in there But what we've done I already got everything marked up here what it's gonna be when we put it back So we're taking the old Milwaukee here and literally are going through and cutting in between here So we can put those on per relay per relay. That's what we're doing right now Which is crazy, but you have no other choice unless you want to pull the pins out one by one Potentially screw up which you do have all the wires labeled, but this is a lot easier So we're separating them that way there And then we're coming in Trim it up a little bit pop off the extra and that's what we're doing This is some crazy stuff normally would never do this on a newer system But like I said, you're not going to get parts for this thing anytime soon Why waste a bunch of money on it the thing needs replaced, but it's not happening So this is what we're doing Now just keep in mind I've got to switch all the pressure switches and temperature inputs and stuff like that yet So right now just to make sure it's working I'm just switching the compressor circuit only to make sure it don't lock out So I'm going to put the circuit that supposedly locks out on Circuit a and make sure it runs and if it does then I am confirmed that it is the board It's bad and that we can go ahead and continue further forward with it making this thing run This has been a real learning experience That's that's my first problem child to start off with is something that somebody else has already doctored and tinkered I'm not a train fan at all They should have made these mirrored opposite of each other that way you could have went pop pop pop pop They did not do that. Nope We're gonna switch k11 with k3 k12 with k4 k1 with k5 k2 with k6 that's gonna be my circuit-for-circuit and Down here on the board. It says k11 12 1 so even though we're gonna switch them I know where they originally went, which is why I did it like that. We're going through unfortunately having to trim Wire ties galore here. The thing has one good one working compressor here. That's that's what we got one working compressor When I put it in test mode it would bring on this one But would not bring on that one and this one actually has a locked rotor It was pulling a hundred and think a hundred and something odd amps. That was yesterday Like I said, I stayed here for a while yesterday gave it my all went home Studied this what this is gonna do is it should fall down an alarm right away It's got a timer that lets the solution mix first what we ended up having to do not only did I have to switch the outputs from Circuit a or let's just say circuit one to circuit two Obviously that was the first start, but the thing I forgot to do which I'm gonna pull a blame it on somebody else card But we didn't want to switch the proving switches because we figured the proving switches would be under their own Category because that's what they had them over here. They called it a compressor proving input Whereas this over here was the compressor protection circuit or whatever the trip circuit So we figured it was under two different labels, but it's not they kind of put it under the same one So what we ended up having to do to make it simple to reverse it if we need to we went ahead and jumped these here Over to here and that one would have been there if I had two compressors, but I don't taped off the ones that are there I should have probably just done it up here. I finally figured out where they were I literally had to go through here and trim some of these up So I could have switched from here and here that would have been the easiest thing to do Which I'm about half tempted to put it back, but whatever now that I've already got it running. That's finished See right now it thinks it's running circuit one, but it's really running circuit two So one and two are swapped. It don't know the difference, but all the protection circuitry is still back in there once it hits about 80 degrees area, I noticed that's what is bringing on the Condenser fans here, which are going to come on you kind of come in here status. There's your set point 65 degrees Entering 79 leaving 77 and dropping K 11 is on 12 locked out by the hot start Which don't matter because they ain't gonna run anyway K 3 is enabled and 4 is locked out saturated condensing temperatures So unless it brings that on which it's bringing it down and temp there It kind of shot up there pretty quick. What worries me is when it gets warmer out We'll be able to keep up. I'm assuming it probably will because we are running circuit two over here on that one there And it is pulling it down. Oh, and then we had to switch the Silinoids here, which I haven't showed that yet on the schematic But it is there so that was the silinoids because those obviously have to open But that was done by the main disguise already once before So that's done. Basically when I originally got here I checked all my circuits there and it was fine and sure enough it was kind of doubling back here The problem we had down here was is the outputs on the one relay because it tripped out so quickly Partially because I didn't have the proving switch on the contactor closing But also we have a bad relay here or the relay that always controls the first contactor to want to come on Was not sending power out on that one. It was best just to measure crossed it sure enough it had open So it had 120 volts there. That was the problem there. You mark things out here. It's running. It's a turd It needs replaced very badly. You know, hopefully they'll they'll choose to replace and not not repaired other than that guys I hope you enjoyed it. I surely didn't but you know, I am prepared next time I run into one of these what to look for There's only one way to learn and that is to dig in there and get at it Especially on something this old one of them things where we got her and we're good to go
