 all right so we got a rooftop unit here that the complaint was it was hot downstairs smelling hot anyhow yet it was cold too and i got here and i opened it up and the motor uh because the motor sounded like it was humming like it wasn't running they said they just replaced this thing which uh we're gonna look and see here's 230 to 240 so check voltage i would say it's probably 460 so i bet we got a motor that's gone out on us here and that's why they were smelling stuff plus the uh belt's loose big time so uh feels like the bearings went out holy crap we've got trains everywhere just blowing their horns yeah the bearings went out it looks like holy cow i don't want to know it's not one to move on the motor look at that she's not wanting to move i think seized up something fierce that's kind of crazy huh a little odd let's see if we can get this thing both loose here just let me get it running for him there we go the bearings are gone holy cow i think i'm gonna take this belt off yeah that thing's shot that's come back for that the regular blower bearing seems fine i don't have no play on it seems to spin fairly good we're gonna need to change that motor though that motors had better days bearings down here feel good on it too this was a johnson unit didn't know they made a unit johnson controls didn't know they made a unit reminds me of a york or something like that okay so let's check the ignition system over here and see if there's any other issues with that because i hate to just order a motor and then uh have there be other issues okay so you have to take all that cover stuff off to even get into this thing power is off these things don't look like they've been much done to them yeah this thing is a york gotta be a york it's got that stupid pilot assembly that they like where uh yeah standing intermittent pilot comes down to there they spark on that that lights a little row across an inflamed sensor senses it over there then it brings on the main burners i do not like this system at all so we'll uh turn it back on just to see if uh things got got some issues i'm afraid to let it run because it might end up cutting into the linings and go so i'm going to uh kill the power to that thing first and then we'll let it see if it'll start up the pilot all right so got the power off i need to tear it apart yet because this is 460 volt i unhooked it and i got zapped so you should always check that before you touch it because it don't feel very good and i was on a rubber rough i don't i don't like that that kind of sucks so somebody did a hodgepodge of a wiring job to all i'm gonna guess so we're gonna check this thing onto the breaker screwed up or what okay last time i checked three phase doesn't get wired like that i don't know what they've done but something's not right here something's definitely not right somebody's been doing some hodgepodge in us this uh motors three phase also so i'm not gonna have it on the truck i'm gonna have the maintenance guy kill the power from down below i've not worked on one of these units before so i'm not familiar with it which sucks do they have a disconnect box somewhere else around here it does not appear to be i wonder if they cut corners and got their contract cheaper so they could like not put disconnect box on it unless that's not the way it is i'm gonna call the maintenance guy and kill power to it all right so i'm looking at this fancy inspected electrical job i i'm not an electrician by trade but i'm surprised you're allowed to do that that just to me looks like that's not the right way to do it so if you follow the wires up there's two of the wires going to the breaker the other one looks like it is what do we got there yeah we got a yellow one an orange one there should be a brown one going somewhere i think that brown one comes up it comes in here yeah that's what i would do i just run the brown one wherever i want to i bet you they lost a leg on this breaker wow look at that look at that look at that hunky donkey stuff ran that wire right through that hole right there this is you know you figure 270 some volts per leg and then they came straight down here to the bottom so they must have yeah that's the problem they have one leg out on their breaker and then to save money instead of replacing it they uh freaking bypass that thing so yeah that's that's not safe that's a bunch of crap right there that is a bunch of crap that is not safe that's ridiculous my stupid butt for not checking it guys definitely my my fault so found this up here on the roof i don't know what the heck that is nothing treasure allowed to have stuff like that here we'll uh we'll bring him along to keep us company we can get it done all right he's gonna sit there and watch while you guys watch i guess everybody's watching so we'll uh we're gonna try to replace that missing piece there i think the maintenance guy had some different ones this one right here's aluminum just like that one so it looks like it came out of a breaker i'm gonna try that if that's a case that'd be great i'd rather keep a breaker and uh all nice and in place than dink around trying to put the box external of this mess so yeah it's not working out so well it's just a little bit bigger but that's how you need to get in there it's one of these that makes it a lot easier it's dissimilar metal i am going to try this one right here and see how that does just for curiosity's sake because i think it's about the same depth real dang close the same depth try that real quick look at my apprentice over here he's sitting there laying down again just just take a break buddy you're paying a butt so anyhow not the idea situation but you know what it actually holds it and i can pull on it and it's not coming out so at least somebody gonna get their crap shocked like i just did this hodgepodge-ness going on over here i'm not even sure what in the world they did not sure i want to even find out i'm not i've i've never been here before i know they got step down transformer i believe over there for some other stuff yeah it's 230 volt draft motor nice why would you make the thing 460 if you ain't gonna make it all 460 interesting all right so i'm gonna go ahead and have him turn this back on i'm gonna go ahead and unhook this here while we got it dead though all right so we got this taped off for now we're gonna set that down here just long enough to test this thing out and then i'm gonna have the power back off again okay it's starting to rain which is always wonderful let's go ahead and see what's going on with this i haven't heard an ignition spark yet got problems one two three four five six six flashes high temperature switch open i wonder where that's located at well now that we don't get zapped look at that it turns off make that nice so let's see if we can find this open switch all right so there was a high temperature switch you couldn't see it but it's right back here in the back so got that pushed and it's blinking happy fast but is that going to make it come on looks like it's wanting to but big old train just backing her up kind of noisy well i'm not getting a call for heat or something i ain't sure what that even goes to something about this is off for dima demo or doing demo account or whatever um i bet when i think tripped it probably just ran the fan traffic motor just because it's probably default kind of like a plenty uh limit on a furnace trips the fan blow the fan blower whatever you want to call it the fan runs so i've got some automation stuff in here which occupied common there's our so see if we can make this thing run good time for the cover stinking rain's getting all over the place let's go ahead and kill it that way we don't accidentally short nothing go into there good w1 supposedly thermostats calling but there we go good now the reason i'm doing this is because i didn't want to order parts you know and then wait a few days to get them and then get up here and find out it won't light up the flame so there goes the pilot it's kind of going across and may burn should come on we don't want to run that for very long so we know it works so we're good on that we'll clean that flame sensor up when we come back but that uh at least gets us to that point so we uh we'll be ready to go as soon as we come back with a blower motor kind of a simple one but not the the greatest thing moral of the story here guys um and i need to start doing it more often myself uh start checking to make sure the power's truly off especially when you're getting into the 460 range i mean it was only 277 but still um i don't like it kind of sucks so that's what we got guys so i'll get that motor putt on soon as i get it not a whole lot to it obviously four bolts and get it on there if you like the video and you want to see more like it you know what to do until next time guys we will catch you on the next one
