 So this one's kind of an interesting one. It's a little cabin. Okay, so I get here And they had some guy that usually does whatever in here And he said maybe the motor was bad, but I see a fuse missing out of the control So what we're gonna do is we're gonna put a jumper with a fuse on it in here Because chances are they have a short basically we'll put that on there see if it trips So we have 24 volts. We've got 240 coming through the breaker Nothing came on. I got the fan switched on and the thermostats calling for heat. Nothing's happening This next thing I'm gonna do is I'm gonna check and see are we getting any power to the Sequencer which is a old-fashioned you new guys probably don't see these very often But basically got a little heater element in there gets hot and it brings on the heat or fan Depending on what it is. It's hooked up to it by a bimetal switch right there The very bottom gets hot and just makes a little bimetal go pink and it closes the circuit Flipped on the power didn't even hear it click with the low voltage breaker if you tripped Turn it on Not much is happening But here in a second it should call and it should it should trip but I went ahead and unhooked it here. What we're gonna do is we're just gonna isolate this thing from the circuit from the thermostat Because we've obviously got a short somewhere and unfortunately they got a heat pump hooked onto that So that means we got extra common wires. We've got wires have come out to the outside unit All those things can create more issues for potential short now that we got that there We still got the breaker hooked on To the unit Let's go ahead and hook up our jumper here between r and g See whether the fan comes on That she does not there it does So we don't have a problem with the fan now. Let's see whether or not it shuts off It's got time delay. I don't feel like waiting all day for it. So Go ahead and flip it back on let's go to g Or let's go to y or cheese Louise All right, let's go to w now. This may have to have a call for g at the same time So we will listen to hear Whether we hear any clicks Or we can watch the amp meter here Which I am not seeing any amperage being pulled G and w both See if that does anything for us They've got a Heat pump out here and back. I kind of feel as though there's probably a short out here that's causing it This thing is pretty cool You can literally hook it Right on the two by four there like that It's got the swing down Light and you put that bad boy wherever you want it at and you can Turn it down a little bit lower Lower that's the lowest which is more than what my Little turd here has been doing But you can see it screws with the lights Because it's pulsating in it. You can't see it but the camera can okay, so it doesn't do any difference I've taken all the way to 240 frames a second. I didn't do no good We'll leave it there for you guys so we can get the best picture possible Because that's what i'm all about originally I jumped it out and it worked fine and the fan came on This time I feel my breaker may not be doing so good So um, but far as it's blowing it could have been other issues We'll check to go around for each wire to see if that's got anything to do with it All right, so since we've got a breaker box right outside, we are going to go ahead and turn it off We're going to remove the breaker and see How it does without it and then we will get that later because otherwise i'm going to drive all over town looking for a breaker Wasting time just to find out we need other parts So this is fused at the breaker box, which is Right over there. So it's not like it's going to hurt anything Um, it's not even the right breaker to begin with you got a 40 amp breaker here on 10 gauge wire So that's not even suitable somebody's already got the wrong one in there Or I should say they ran an undersized wire to the furnace that probably required bigger This is what happens when you sell to the general public What do we got here heat strips? It's got two strips. So two strips are gonna probably be about 45 amps. So they're probably not even got the right size of breaker Look at that. It's dead. I think that's terrific Yeah, look at that. It's gotten so hot That the insulation is cracking off of it That's That is terrific right there All right So that gets this power to the other leg or break got the breaker protecting one leg Not idea at all, but This is 7kw. So that's probably why they've gotten away with it 7k so P over ie Do the math on that 7,000 watts divided by 240 volts Is 29.1 amps. Let's add about six amps for the blower. So you're at 35 So yeah, we're a little bit on the shy side. You're supposed to have 20 percent over under that underneath your maximum rating So you're about two amps over You're a little shy on the happy spot. So 40 amps minus 20 percent Should be pulling the more than 32. So All right, so we've got to turn back on Do we have juice On your caboose Yes, we do have juice on the caboose. Let's go ahead And get in here with out getting shocked Get that hooked onto there. This is the breaker for the low voltage Like I said, it was tripped prior to Do we have a short do we have a breaker that was just weak? Okay, so we haven't tripped yet. So we're gonna take our r We're gonna go to g See if g comes on Come on, baby. All right, so we know that that works Let's go to w Let's check amperage There's 31 amps so The furnace works Problem is not with the furnace. Our problem is going to be with our low voltage and the breaker The breaker just so happens to be one of the issues they had We just basically went through and narrowed some things down Now like I said Technically, they're right at the absolute maximum current of what 10 gauge is rated for which generally is 30 They're right at 31. So they're technically undersized. They should have went to the next size up, which would be an eight gauge Um, which would be somewhere in that 40 amp range And six is usually what we would run Which is technically between 50 and 60 depending on what book you're looking at and whether it's single stranded copper aluminum A dog leg, but I can smell it working So I know that both strips technically are working right now. So here's one leg of the strips Coming in at 14.6 There's the other one Coming in at 14.6 So both elements work. So we wanted to make sure we had all of our inventory figured out what we're going to need When we do this, so let's go ahead and unhook That from the circuitry We're completely unhooked here There we go. Wow the elements shut off at the same time as the blower, which means they're not cooling them down completely What a wonderful job. They did designing that so um Let's go on to the next Co-round of things Let's go ahead and check our thermostat wires and see whether or not we got continuity to ground on any of them Let's go to common on the transformer Let's go to g Look at that All right, so let's undo this blue wire, which I am not 100 certain what that is Let's undo it that way. We've got our thermostat completely. Oh, yeah, that's not what I needed That means it's starting to get a little dead-ish Okay, quit blinking. I ain't got time for you to blink. All right going back to Our common here So we don't have anything to there nothing to there Nothing to here and this is how it goes guys. You'll be down here in the crawl space And your um freaking lights decided to go dead So let me get another battery for that But it appears that our problem is probably in thermostat wire somewhere could be on the y terminal Like I said the outside unit looks like it might have some Jackery going on so Let's touch those nothing. Let's go to the w circuit here Got to check that out yet Nothing on that one either So we're isolated from that. Let's go grab a battery real quick. This thing's getting upset. All right, so while we're Finishing testing things out here. We're Getting rid of the wires that have been twisted a million times So they don't break off in the wire nut and creating a callback for later We have unhooked w2 that way only one strip is going to run which will keep our amperage below The threshold of what the wires keep both holding Because I don't know if uh, they're going to Want to do that themselves or what because I mean that They've got like a little maintenance person or something obviously so They may want to do that and I haven't talked to them yet So basically there's rw and whatever so need to get How the white people would use these little gray ones these things are so small they don't really do much Let's go ahead and hook that up to r here See if we can trip a trip a breaker Move oldage breaker. I tell you what we're just gonna put the jumper to it because it's too much Effort to get that over there So there's that Yeah So like I said, I've got the fan turned on so that made it do its thing I'm gonna go up there and put it on heat only And double check the wires to see if they need common hooked up because if there's a short To one of the other wires at least then that would just cause it to Cause one of those other circuits to run and not blow the fuse completely taking their heat out That's my kind of work logic. But uh, there's the heat. It's at 30 amps So they have heat now Whether they want the heat pump to run too or if it, you know, they're even using it I'm not sure I'll have to talk to them about that And wait a minute here that's pulling 30 amps still So really the other terminal wire there must be jumped somewhere internally in there because it didn't even make a difference Yeah, well, I guess that is just a single stage That's a single stage sequencer. So that's probably why I wonder if that's original or not. All right, so I went out there and looked at the heat pump Say it was so screwed up. It's not even funny. The thermostat was wired wrong. They have it hooked to be not o The outside unit says oh, so I assume that it's supposed to go to o Um, they had common ran upstairs. Don't need it's a generic Want to be hunted honeywell thermostat? They had y jumped over to w1 so I can see You might have wanted to run auxiliary heat with the heat pump But generally you do that with an isolation relay So how this thing ever worked in cooling mode is beyond me because it would have been making the electric strips run when they were doing the Y terminal. So I corrected all that garbage ended up Correcting the common wire, which I think might be where my short was So i'm gonna correct that here real quick and see what we get if we have any more issues with Tripping of the breakers and stuff like that or the fuse as I should say There we go now we got a little wire to work with here Funny thing is that's not even a heat pump thermostat really They don't have a w1 w2 Uh hooked up on that thing so Now trying to be a better person we can put down that stat wire so We're still pulling Too many amps I believe so let's go back and look at that again Yep, she's pulling 31 The outside unit I don't know if it's even trying to run I honestly if they're not using it I'm gonna unhook it and run it straight as air conditioning. I need to talk to the office and find out All right, so this is the outdoor unit that will all jack to the whole new level Clean this jump All right, so coming down here checking to see if my wiring is any good out here I do have 27 volts On r2o to common From common to y I have nothing So it's obviously not a heat pump thermostat Coming to the O terminal. I have nothing Not really there My question is Are they really using this thing as a heat pump? I don't think they are so Says heat on like I said, it's just a regular honeywell Just has Heat cooling off No auxiliary BNO so For giggles Let's go ahead and put it on cooling Make sure cooling runs. I don't even know if it will even run because it's 59 degrees and you know, of course this thermostat goes down to 50 degrees Because you should be able to run your air conditioner that cold. That's normal Oh just heard something kick on Sound like the air conditioner. It's running It's always a good sign. It feels like some warmth for as cold as it is out here Suction line is cold I would say she's running in cooling mode So It's never going to run now auxiliary heat or any of that stuff like they had originally but They got the wrong thermostat for that It's hooked up, but they decided to change it. So we're going to leave this thing go and uh Go ahead and get the breaker for it and then they should be good to go. We're not blowing fuses and now so Should be good All right, so going in here looking at the furnace for the heat. It's on a 30 amp breaker Outdoor unit is on a 20 because it's like 12 gauge ran to it the heat Is undersized It really needs changed wouldn't be hard to do So we're going to go ahead and mark it up that it needs to be corrected We've got it temporarily wired up that has to have a new wire pulled Right on the front of the unit. It says it needs a minimum of 40 amp circuit So they need to pull probably an eight gauge and uh Put the right thing in there that was manufactured in 2004. So I'm going to assume it's been in for a long time We'll let them know. I'm sure they may not appreciate that, but it needs to be done correctly. So I wraps this one up guys. Hope you enjoyed it He did smack the thumbs button. We will catch you on the next one
