 All right, so we're here to check out an air conditioner. It isn't cooling well basically it seems that Got rather warm in the waiting room And my best guess is it's this area right here so we're gonna Unfortunately since they're all crammed together I'm gonna make an educated guess. It might be one of these really stinks when they don't label crap Tell you what I'm gonna do We're gonna we're gonna assume this is probably it we're gonna turn it off see if the thermostat goes blank That's another generic way you could do it. This is gonna seem like it's a little bit overkill but I'm trying to get this done quickly and I hate wasting crap a lot of time but this is a tracer unit and use these on Data and you can use them on telephone telephone was the big thing they were most common for basically just Turn it on you either get solid Or you can set it for a beep and we put it on thermostat wire and we'll go up on the roof and This is analog. I also got One that I use for electrical tracing tube idea So as you've seen the bottom thermostat was this one here that was dead So obviously it's not this one. So we'll go ahead and turn that back on before we forget Obviously probably wasn't this one Because This one's still running This is great such a lot of wasted time Look at that There it is It's that simple or what? It's a pro 3000 probe. I'll put a link actually check the toolbox section of my tools I'll put a link to that to the Amazon link and help support the channel But what I did is I just picked G and W because I knew they would probably not be Shorted together up here in the circuit board. They are but they aren't so this is the waiting room. So We'll actually write it on there. Just the waiting room with a paint marker, which It'll last for a while Now let me know which units which not be noticed when we got up here this unit wasn't running So let's go ahead and check high voltage And see if there's any issues with that just for giggles the thermostat had power But don't necessarily mean that that's anything in particular going on, right? 215 217 217 so five-voltage is good this one here is Got fan operation, but I have no compressor Signals getting up here. No I don't have anything on that one. You have it on R So I ain't got nothing coming from Y off the common on the transfer. Yeah, I do know I do Got nothing there on that But look at all this hornswog with garbage This goes over to a pressure switch. Ah Look at that. You see that always like people that can't afford a good pair of crimpers That's nice stuff right there Just smash it Comes in goes to a black one goes into all this looking mess. What a freaking joke So basically blue goes to the low pressure switch goes over the high pressure switch and comes back on T1 See the high, but I don't see the low pressure switch I think it's there hidden inside there so there it is it just tried to start again And that time I didn't touch anything At this point, I'm just gonna kill the power We're gonna go through and check These switches which blue one comes into here. This is such a mess Clean this stuff up one connection here one connection here connections galore what we can do is bypass that garbage basically This comes out of here on that terminal Comes back on black We're on blue. I should say so Go to like that It would go a little bit wider that way you can get a better view of it. It's not super wide So basically just bypassed all the circuits That's low pressure switch coming in here. I don't see any shorter wires Okay, might as well check our belt and T on this So we got going on here I think what we're gonna have is just a bad pressure switch 17 degrees split on this We're on a 29 degree of app Charge is probably fine. Not where I think it should be at. It's an 04 So, you know, it's only 16 years old It's 71 degree here coming in 52 going out. It's not all bad. Let's say we're fine So our biggest issue we got going on here Was mainly it wasn't running because of the pressure switch now. Let's see if we can figure out what's going on Which one it is I've thought about building a device that uses like a D battery or something like that You put a load on the switch is what you'll run into these switches is Though, you know, you're putting less than a couple of volts with no amperage at all behind it when you're checking resistance So if you put a load on it say, you know Something that pulls maybe an amp a current you can do the resistance Calculations You could make the switch open up once it has a little bit of a, you know, some amperage on it So right now we'll check resistance again, but it's gonna show probably closed Which is why it acted up once it's put under a load Yeah, see Resistance is not always reliable because it's no load on it Now to double check that you can come over here and check your amperage on your contact or for giggles Just see what exactly it's pulling Which generally is not real high So you're pulling two point two amps point three amps. So we don't have excessive current That's not the problem Honestly, I feel like just replace both pressure switches and be done with it They're Not gonna replace these units anytime soon. So you might as well just get them both replaced it's If one went out as the other one getting ready to go out So you can consider that preventative maintenance Recall and see if they got them available So I just called the distributor. They don't have either one of them in stock Costs for both pressure switches is 30 bucks. So I'm just gonna replace both of them And then we'll come back right now, we're gonna go ahead and leave this bypass to get them by So we're going to Wire this thing back up so it's not across this panel like it is. All right, we're here We got a couple other units to check out Basically had someone out here to do the maintenance and they found some weak capacitors and a few different Interities with the units maybe not performing quite right So we're gonna go ahead and check it out Something here was slow to cool Okay, I just went downstairs and turned them all on. I only went like two degrees down same thing here. Let's Put the probes in here and check stamps Of course, it could be just stabilizing Gotta love the old 410 like I said before it will trick you into going and grabbing your refrigerant bottle and About the time you get back It will end up being okay So from what I'm seeing here It looks really good 17 and a half degree split and 35 Vap and 91 condenser Not bad. That all can be thrown off depending on where you take your measurements at I see some of these people sticking them thermometers in the screw hole of the 516 hole and stuff and air is funny. It doesn't go everywhere equally So your best place is in the middle of the duck if possible It just really depends on how the air is bending and twisting and everything else So that right there on this unit is fine. No problems at all. This unit here the guy found the capacitor weak so Came up here and checked it And sure enough it checked out a little bit weak. So we're gonna go ahead and change it This is another one of those dual capacitors They carry your likes to use which I don't stock on my truck but There's nothing wrong with using two individual ones. So as you'll be able to see We've got eight on the one 7.8 on the other it's rated for 10. So It's getting weak don't wait till it fails You know the old saying you were just out here. So It's going to give them some new ones on there. We got to split the common away from them and We'll get that back in place the elder We'll put there And we'll just make a jumper for the other one I usually try to carry some wire in my bag just in case but as you know carrier likes to put 60 foot of Wire here for their fans. So what we ended up doing was just trimming a little section off of there We'll go ahead and put a new crimp on on it And then we'll put a crimp on on the other side of the other and that will make us a nice little jumper Which will save us a trip Back to the truck. They had three wires on there. Otherwise, we would have had to we could have just split that yellow one but When I'm going back in there and we brought a little bit of strap so that it's not just dangling in there There's all kinds of capacitor bandits out there that Just throw the spin there wherever they can make it fit and that's Gotta be better than that. There you go Got those capacitors in place. They're not going to go anywhere parents Not perfectly level, but you know It's better than setting inside of a box loose inside the compartment, which is some of the crap. I've been seeing online lately It's bothering me that's It's turned See, that's the kind of crap Just bothers me so Let's trim that up. So that's a little more straight and Unfortunately, I'm gonna have to use a tapping screw To get it to their level and that screw is not really pointy on the inside doubt We'll put this into this Warp speed and see if we can make this thing bore through it do the hole ahead of time Look at that That's stage three on this puppy man. She's wicked That thing wasn't even sharp It just sucked it right through That's why these guys strip the freaking screws out like they do. They have no finger control Watch one guy not too long ago every one of them Now after it stopped clicking and he stripped it completely out then he would go on to the next one It's like dude, you must be a hit with the women. You have no finger control So anyhow, you got to have finger control That sounds like a Dave song finger control kind of like the Prince song The P control Sounds about like something Dave could do finger control crazy Dave nor Cal doing the Finger control song. That'd be kind of cool. I think I'd be neat So anyhow, this is been modified and corrected. So it's wonderful Go ahead and put it back together. We got one more Magnificent Capacitor to change and it's on a blower motor on one of these and Then I'll wrap this up Got put it on finger control mode see you can use a Impact you just got to have finger control
