 So they got us some McCall here that I suppose it was 100 degrees this morning and they unplugged it luckily so we're gonna check see what's going on it was working fine earlier like it always is so gonna plug it in see what it got going on gave it the sniff sniff test it smells like food in here so let's see what we got looks like this has had a few things done to it here probably why they spent so much money on this thing so far it's like a 2011 the compressor was released yeah that's better all right at least I can see what's going on there until the start components have been changed once before the compressor was changed in 2011 pretty much everything else has been changed but it looks in good physical shape let's plug it in again just make sure it's not pumpkin it's 2000 so this thing is 20 years old and it's 115 volts so and it runs on r22 sweet so yeah it's getting a little old there at least but gotta admit this is a pretty nice cooler and it's in pretty good shape seals are in good shape I mean you can replace the components in this thing and get a lot longer life out of it I mean when it's in this good a shape I don't see any good reason to can it just buy one of the new things that are gonna fall apart even quicker so let's go and get the ante on here see what we can find out so we got that on there let's go ahead and see if we make this thing run no good place to put my camera because everything's aluminum here we go these buzz goods are gonna get it today here are giggles let's go ahead and put this on ambridge and I'll watch it with that just in case and uh we'll just push it out on our start flip it on and she's running she's pulling eight point whatever amps if you look down here it says six seven eight so right in there about the eight eight amp mark and she's running so ambridge is not going up it's actually dropping like it should so we got bad start component simple as that now here's what sucks look at the suction pressure there on that gauge so we've probably got a grand the fans are not running but uh that dropped down off a low very quickly so we probably have problems with the uh with the refrigerant charge possibly we won't know until we get the fans running um I'm just going to uh see what they want to do if they want to have me order the right ones if you want to use one of three and ones all right so we got the start components for that compressor I'm gonna get those we're gonna get those put on once we get done with that he wants us to look at a makeup air unit that doesn't seem to be heating the air for the kitchen so we're gonna look at that once we get done all right so I got my goodies up here see if we can go ahead and get some of this stuff unhooked power's been off for a while if you remember we had some issues with the pressures so we're gonna have to double check those and maybe it's something maybe it's not I get that there just like it that's good we went with oem parts stuff for the capacitor POV lead resistor here this comes all made up with the uh a little bit of a spacer and lander put this on there next as best as can be expected I'm gonna use a little piece of duct tape to hold that in place there we go not to what I preferred versus having an oem capacitor but it'll work out just fine all right so got it all in there should be able to plug this thing in and watch it start up so good so let's go ahead and kill it see if we sniff a leak out here what's kind of concerning is we got 45 50 about 50 60 pounds of suction pressure there so I hope I'm hoping it's not a restriction of some sort I don't know if this one's a txv or an orifice so go grab the leak detector I know we definitely get a lot of leaks in those freaking condensate pan all right so we just scanned all this we didn't pick up anything just uh need to scan the inside which is usually where my leaks are usually found at all right so here's a little bit better look at what we're working on here at six doors so this is definitely not a cheap unit I think they got a quote for uh eight thousand dollars something like that so these are kind of expensive for a quality one uh 66 degrees starting drop um it holds 20 ounces of refrigerant a lot of times what I'll do is I'll uh just pull the charge away it in but I'm going to uh actually just add a little bit and see what we get I'm checking subcoil and super heat and all that happy jazz generally they won't give you any of those measurements and a lot of times it won't work this one here doesn't have the uh receiver so it's going to have to stack in the uh condenser coil this comes down to some experience level that's why usually I just pull the charge and just weigh it in but I'm keeping track of what I have and so far we're like at 10 ounces out of 20 we've got a seven degree sub cooling and our head pressure is running 106 degrees and it's probably 74 in here so 84 94 104 so about 30 32 over in the end so we're probably right in that ballpark area right now super heat pretty much is not anything to brag about which don't surprise me a whole lot so boxes and that temperature and so on so we're going to let this run for a little bit but uh basically like I said this thing's got a refrigerant leak in it it's had a lot of work done to it over the years pressers txv start components you name it but the box is a really good condition because this is a cafeteria and uh so same people always working with it so it's not abused and so it lasts quite a while like I said I do not recommend this unless you have problems and so right there's your txv normally I put my probe up a little closer here but it's kind of warm in all the different spots so I do one more turn and all the quits because it's been working good up until you know they went low and start components went out but I can't help but wonder you know is there an issue with the compressor was it basically overheating which is why I'm kind of adjusting it because it just appears that uh the start components have been getting changed an awful lot and uh like every two years so it's kind of reason why I went with what I did and she just shut off before I had the chance to do it so we're right there at 35 degrees I'm going to leave it alone sometimes you dig yourself a hole we uh went a total of three total turns out I even wrote it there in case I ever need to put it back the way it was that's a big thing make sure you keep track of your turns so that's going to wrap this one up we got to go up on the roof now and check out and make a very you know all right so I think the plane was basically it was cold air this morning so we got a captive air hood and uh exhaust fan here it's not the strongest feeling in the world so let me double check the belt and it's loose as a goose so that's not helping much so let's get that fixed I should go down and grab my crowbar to pry this baby over a little tighter we'll see if we can get it with the screwdriver which ain't really the greatest way to do it I have to say a lot of our issues it's already about as tight as it can go now that I get looking at it you see here I only got about a little bit more we can go a little bit further with this thing I prefer way of doing these with the box wrench like this offset makes it a lot easier there we go that's almost the absolute maximum that can go what belt is this one it's a 4L220 it's got a nice clogged belt here it looks like it's new maybe let me try that one instead probably a used one honestly it appears it's going to work let's see if we can tighten this thing up a touch it's pretty much about about as fur as it can go yeah that's not too bad though let's see if we can get these nuts to tighten up here a little bit with the store here you know that's why you gotta look it all over they definitely got some good grease on that thing probably should have gave it a little shake made sure the bearings are all right which feels like they are see how it runs now those aren't level horizontally together doesn't look too badly off really probably needs to be a 410 belt I think I'll grab my pry bar on a level tell you what why don't we just go ahead and get on to what we were first started to do got that let's go here and see what's going on with this this thing's probably got loose belts also which would make the heat not come on because it has a pressure differential switch that's fairly tight pulley's fairly new or two not too bad I bet you maybe the limits tripped on it check the filters looks clean oh looks fairly clean let's turn this thing back on sounds like they got a damper kicking on that's not tripped maxi troll set for 70 just does not appear that it's getting a call to do its thing so I can hear let's check our pressure switches all right so our dampers are open but pressure switches didn't show as an open circuit so may double check our limit there so it doesn't look like we're getting power to our controller so I went through everything made sure my pressure switches were fine with my meter there I've got like 0.3 we're coming in through the low pressure switch and we're going out with the high pressure switch safety so basically if it's too high or it's too low it that switch keeps it from happening goes over here to the limit blah blah blah comes over here to the fire I fire I's got a neutral and a six wire which is low airflow switch I've got a hundred and twenty three volts so it appears to be we got a bad fire I control I don't have any any lights on it or anything if you look at the back of it tells you right there pilots main burners all that stuff ignition all those are outputs basically lockout alarm it's going to be an output to tell you that's tripped neutral line limits operating control I suppose we could look at number seven see if there's got power on that all right so I feel like an idiot now the burner on and off intake air thermostat I guess I was kind of thinking it was a limit switch meaning like if the burners don't run because I've had this on their bigger units this basically has to be below that temperature before it can come on which I turned it up but I didn't you can't see very well but I'm going to set that at 55 it works when I turned up to about 58 which is probably about the ball park where we're at everything worked you see the light come on there we got airflow we got control operation it's modulating so for the most part everything's working you can hear it kick in right there I checked the voltages on it and it's modulating so I'm gonna like I said set that about 55 and that should be good enough for them so anyhow that's going to wrap this one up too so I went ahead and got the belt aligned it's a lot better than what it was now so that's going to wrap this one up and until next time guys we'll catch you on the next one
