 okay kids we've got a rooftop unit that does not have powers what i'm assuming because the thermostat's blank i checked power at the thermostat and we do not have 24 volts so should be that packaging right over there fairly sure this is the entry into the building let's see what we've got going on everything here is electric because that's a hundred percent efficient not cheap but it's a hundred percent efficient of course haha i'm loving it hell yes that's nice let's see if we got power here now the only reason why i killed power and not check for codes first is because this is all electric and this is older it does not have any codes so nothing was erased usually your power comes into your top and i have power at the top while we got it open let's go ahead and check our fuses good good good we got the breaker off so obviously only live ones is these over here so try to stay out of that that is just nice the birdie's got in through that little hole right there it'd be probably good they got that closed up actually right there is the knockout for it that somebody screwed up and took out by accident look at that all right they've been evicted i'm gonna head and turn the power back on now that we know that we ain't got anything we're going on down here that could cause an issue let's go ahead and verify that we've got the power getting through the forks and everything which it should really ain't a good reason why it wouldn't it's going down to here 216 214 214 so we're good on that okay we went ahead and yank the cover off because this place hasn't been getting maintained because of all the stuff that's been going on and i have a funny feeling here's my prediction okay because it hasn't been maintained the bell is loose you got a rollout switch there you've got some major electrical strips down below fans not speeding fast enough did a trip heard a click but i don't think it was a normal click let's go ahead and check our voltage over here and see what we've got going on look at that kids don't even have to check voltage the blower kicked on look at that watch how fast it goes when pushed down on it day and night difference all right well these are the kind of calls i've been running into lately just nothing worth showing we could just tighten the belt up and leave but let's go ahead and make sure we check our electric strips out i thought maybe this might be a heat pump some of these actually are heat pumps you don't see that very often you've literally got heat pumps up here on some of these rooftop units around here it's not very common but uh when you get places like this where they don't have gas that tends to happen so we can go through and check all of our oh my look at that the power is off again all right good it's just the outer skin not the actual true jacket so we're good we'll check all that here in a second let's go ahead and get this thing tightened up it's belt off it's not one of our normal belts either it's something from local hardware the sheave there's a little war it's not real horrible let's see if we can get on there oh boy did they lie and change it they changed it what a bunch of dirty dogs i love it when they don't keep things uniform and that is i don't know i just don't know how to read a wrench here's my nine sixteenths i grabbed a half by accident hate when it happens look at that they actually made it the same size okay let's get this belt back on let's see if we can get this thing tightened up a little bit let's get a half an inch there i'll do it it's just like new just like new again let's go ahead and now the question is going to be do they want us to check that one that one that one that one that one over there and the one behind the tree that you can't see to make sure all those are fine let's go ahead and check some of these fuses i just heard a click i think i hear the electric contactor coming on yeah that's your contactors on we're pulling 67 amps fans not running that ain't good let's go ahead and kill that so not only was it loose belt but we got either a fan is malfunctioning or the switch i'm not sure if this one has a switch like a snap disc that comes on for a delay or if it's a straight from the thermostat let's go ahead and check and see if we got a g signal at all for this thing see what we got going on here i'll read the meter you guys just watching my finger placements okay no g yet no w no w no g we do have r we should hear a click when the uh now look at that came on immediately as soon as it had a uh call and a y a w one here called same time okay so the question is did we have a problem with thermostat maybe not bringing it on or is it a problem with the relay that controls the fan hard to say let's go ahead and get inside here deeper get two contactors for the um compressors and you should have this one here usually for the fan and those have a tendency to fail sometimes they may just replace that as a good precaution they're not super expensive all right turning her back on see if it does anything funny this time immediately came on that sucks all right be nice to see it do it again w one's got a call and w two not yet there's no 24 volts to that so that must not be be let's not be our this one here must be that's compressor that's compressor so our blowers right here and they fold that right off there for the ultraviolet light and good grief ain't that kind of scary when you're under shielded wire right above the capacitor like that that's scary well see here yeah i got 25 over here on the coil hard to say exactly yes the strips are being shut off at the same time but these are relays for these strips they're not thermal discs that bring them on so i'm not too concerned because that's how it shuts off normally powers back off again i mean if you push on the edge it doesn't go in push on that side it does it's not worth it to me that one goes in that one doesn't is easy i mean in theory yeah it's probably not i don't know i'm just not taking a chance let's go ahead and get that contactor replaced before we go that route let's take a look at these filters they're cheapies two inches last change december of 19 so we're coming up on two years for a single filter center single uh non-pleted filter and that metal thing there is the ultraviolet led halo going down below at first here's may have 20 i changed these from closed to six volts and that quickly was decided not to do because they couldn't keep up with the capacity so let's uh like i said go get new contactor i just want to check these filters i don't have any on the trucks i'm gonna have to have them do it or we'll have to come back it looks like they are 20 by 20 by 2 power definitely is off and i made sure there wasn't power from another alternative source because it's another issue you'll run into they'll bring power in two different locations because it's such a large amount of capacity definitely want to make sure you check that we got her back in there went diagonal with my mounting bolts instead of two the top screws not bolts let's go down here and check our elements while we got the power off and see if we got resistance against all of them i guess the maintenance is due uh into this month so i won't have to mess with any of the other filters or any of the filters or the belts i guess that all get done here at the end of the month what we have here is power comes into here and here loops back and forth comes over here through the limit and into there so your two test points are going to be there uh went ahead through and through all of them and made sure they were good this way we're kind of testing the limit and the coil itself looks like the contactors have been changed recently or at least they look newer you can't quite tell looks different than that one there this one's got that same kind of cruddy yeah these are 08 this looks like it's 32kw so it's a little bit of a piggy let's check these out make sure they're fine let me add anywhere from six to ten ohms area you see the wiring comes across goes up goes to these fuses which we'll check this real quick and then we can kick it on in theory most of this crap's supposed to check with the power off anyway not that any of us do it that way ours back on should be kicking on here in a second and we'll check out the strips that come on first 6.7 on the blower which doors off so it's gonna be uh it's absolutely highest you can possibly ask for 5.8 is the norm so when we get it back on there it's truly below that we did it like that so we kind of check and see what we got here for the hammer off nothing on that and yet these two here are pulled in 20 amps 20 20 kind of go to the big one 35 see how it's splitting that up pulling phase to phase see how many little piggies we got feeding here we got 76 77 77 that's amazing these are 60 amp fuses and we got six point or 7.3 there these must be feeding up and out yeah they're they're piggyback and out of here they're using this as a junction box clock 28 on that one 28 on that one so this little piggy here there we go must not either had to plant completely closed or something this 28 29 29.8 29.1 28.7 8 28.9 now we're at 99 amps on the top 100 amps and 92 yeah our other strip there did kick in yep 13 13 21 something so all of our strips are working so we said 5.8 and we're at 3.7 3.8 so our blower is fine got our cover on gotta get some tappers because some people don't know how to put the screws back into a unit it's all right guys it's running blower is running the heat's shut off so we're good to go amperages checked out fine we got the contactor here replaced like I said look it I can't even push that in when I push on that side I get it's got to almost be dead center which yes the contactor is pulled from the center but it hasn't acted up since if there's other issues and it's not doing it right now we did the most likely cause and we got it so what else are you going to do I mean the belt definitely was loose that was primary probably what was going on but when it doesn't come on at all it definitely is a problem that's going to wrap this one up onto the next one till next time lighter
