 This video is brought to you in part by TrueTech Tools. Quality Tools, essential support. All right, guys, we're going to check out an air conditioner for some people. Kind of, huh, I guess. I've been here once before. Had a heck of time trying to figure out which one was which. So hopefully it's a little better label than it was last time. See if I can figure this out. I wrote down on the unit somewhere what the heck they were. I'm going to guesstimate it could be this one here. This is what sucks. Nobody labels anything. Probably can't label it, honestly, because of where we're at. And working on that. So I was able to call one of the guys that used to take care of this. And he said it was along with the exposed ductwork. So I've got this one here. Got a J controller that's unhooked. The controls guys putting controls finally. So now we're not using thermostats in the return air duct. And I'm trying to figure out. And he said they did not take control of the economizer. So it's like, OK, it's a little bit chilly out here. It's like, why would you undo that? So I don't think this has low ambient. So we got a call here from what I'm seeing. See if we got to call to the board. Oh, why one, two common and 24 volts? So she's not running. So it's for whatever reason locked out. But you don't exist. This is only a single stage unit. So all right, well, let's find out if that being unplugged, which I don't think it has much to do with it, because it kind of just went from here to there. But try to remember what these wires did. I guess my economizer controller. Yeah, mixed air temperature sensor. So they just unhooked it. So, yeah, well, fans running. Let's see what else is not working. So the compressor has a little bit of heat from the crankcase heater. Pressors here. It could run if it wanted to. Something's shutting it down. We don't know what, though. And let's go see if they put the economizer jumper plug back in. You would think they didn't utilize the economizer control. Took in humidity. That looks like it's got crap on it anyway. Yeah, it's got corrosion. So it's probably junk. I don't look at the schematic. I'll figure out which one's Y1 and Y2 sending and receiving. DDC, T-stat, reheat, which we ain't got. Thermostat. So it goes into Y, comes down, connects to that blue. They just put a boatload of them all together. Nothing really happens. Comes over to here, plugs into that plug, eventually gets over here to the economizer. Usually one and two and three and four are your terminals that goes in there. I think Y1 is going to be one and two, and then Y2 is going to be three and four. What it does, it goes into it, and it may come out, may not come out. So let's go over there and see if we can find maybe the blue and the blue and gray. I'm trying to think or remember here, it's been a while. Don't know why the economizer went in to control when they got fixed, because honestly, it's like for an application like this, you really want it. All right, here's a brown one and a blue one. Let's see if we got some voltage to the ground. We'll just kind of cheat here a little bit. Usually not big for just probing one, one particular one, but there's a brown one. Nothing on that one. Should have been a blue one here. No, no, I'm assuming maybe it was this one here. Got 24 volts on that blue one there. Yeah. I'm going to go grab a plug off my truck. It makes it a lot easier. This is why whenever you take an economizer and put one in, you save the plug and you put it inside the unit so you can just pop it right on again if you ever needed. So this is the jumper that comes from the factory with every unit that doesn't have an economizer. Let's go ahead and remove this. I've got on there. And look at that. Tron in, that's it. And look at that. Tron in, match that. So somebody hooked it and didn't bother with that. Way to go. All you got to do is copy this one here. So you've got the yellow one here. And it goes over and connects to the orange one. Let's two connect together. Da, da, da. The brown one and the one that doesn't exist there. So we know mainly it just needs to be these two here. So let's connect those two together. I mean, I'm not real sure why these aren't getting reconnected or they ain't replacing the controller, but I don't know. Whatever. They just want the cooling to work and bands that control sensor is chunk. Like I said, I mean, we'll hook it up just to see. But I mean, if that being there like that, there's no way for that to loop over and back again. So there we go. Take that, plug them together and it don't run. Okay. So this didn't obviously have the jumper. We're going to have to either get the right jumper or steal a wire off of one of these and make it work because we're missing a barrel plug here. So I basically copied the blue one. The other one is this one here and this blue one right here. So the blue one has to loop up there, but unfortunately it don't do anything. So what we can do is we can steal one of these other plugs. It's transplanted. Have to get a pin removal tool to get it off there. But that's what we'd have to do. So I might just go grab a pin removal tool real quick. All right, so I bought a big old miss flow to these and the reason why I'm not just chopping off the other plug is because there's a good chance I may want to re-hook some of this stuff. I don't want to damage the main plug if they choose to do that. So like I said, we're just going to pick one that's not being used, pushing in. You have to give it a yank. Harder first came out, didn't destroy it, none. That's good. It may just have to pull harder. I don't know. I've never done that on this particular one. I've done it mainly on the hot surfing nighters. You see this is mainly the female. So let's go down here to the one below it, which is right here. It locks in good. Go ahead and strip this and we'll hook it to the other terminal, which is the blue, which I don't know what was connected to this originally. I don't think to chop it off and they may need to have extra length there. Just leave it ugly and long. Now it should work. Feel the warmth down there. That's for sure. Okay, there it goes. Yeah, these come in handy. You can get them on Amazon. I'll see if I can put a link down below. People just be smart and leave these. That would have made it the simplest. Go ahead and check our suction pressure real quick. Looks like we're about 110. We got the door off here. So obviously it's going to throw off the head pressure, but it's cool today. Go to 110 pounds. Comes at 36 degrees. I mean, obviously I'll change a little bit when we put the door back on, but it seems to me that it's working. Now what's really interesting is you've got capability of actually two stage after all. So you're never even getting that. It's only running with one stage. That's nice. That's really nice. Guess may need to jump that, huh? Okay, so out of giggles here. This is going to shut her down. There you go. I wanted to see if this thing gets a power fiddle. Say it says economizer. That one obviously goes to that. This really should probably go to the manual module. Let's see if it gets powered up. Come on Jade. There's Jade. Jade's waking up. Jade's, Jade works. So why didn't Jade get left hooked up? That's what I want to know. All right. Let's hook up the other one here. There you go. Let's go down here and see what the status is. See if it's finding that outdoor sensor. Heck, maybe the outdoor sensor's okay. Let's go to status, available, no. Condomizing, no. Occupied, yes. Oh, there goes heat. That's good. Y1, Y2. Not gonna fly. All right, status update. So I found out that this supposedly works. Somebody was out here in the winter, had some problems with heat or something. I don't know, but the sensor was bad. The one I thought was probably bad and put on the paperwork that we're gonna change it in the spring. Well, it's spring and it needs change. So I gave them the information because it got misplaced and wouldn't have been known because this is why, I don't know. This is the reason why I always try to do everything immediately and get it done and over with and not try to fool around doing it later. It's cold, but sometimes it's just better to get it done and get it out of the way. Flipping the gas back on, throw our gauge back here. I had to mark the wires where they're at on the economizer because when the person comes back to do it, they're gonna have to match those up. And since I switched those prongs, I tried to switch them with one that may not have been used and that broke off on me. So, you know what, at this point, they're just gonna have to wire directly around the plug, harness, and be done with it. I'm gonna let them finish that part up. That's what's going on. Just something happened from the winter time. This is, these are the ones where they used to be controlled by thermostats in the ductwork. So there's all kinds of left-over wires from 25 times ago. I also got the second stage hooked up to the board. So as long as the control skies did their part and did that correctly, programming-wise, it should bring it on when it needs it. At first it was setting or energizing. Also, it's 211, 212-ish. They had that on the lower voltage. So it was running 23.4, 20, whatever. Switched that around, we're running 26 volts. Anyhow, onto the next one.
