 All right, we've got us a true reaching cooler. It's a T49 two of that fans on it I went ahead and took the fans out because I want to find out whether or not this thing's got a refrigerant issue Or if it's a thermostat issue The customer's complaint is it was freezing things. I get here and of course none of the food is frozen and It was pretty much holding up here at around 40 degrees We check the condenser condenser is nice and clean the refrigerant section here hasn't been tapped or it actually looks like it's been tapped They remove the stems if they did do it went off a feel and You know feels hot here and mediocre there, but that's only so good. So right now waiting for this thing to warm up so it'll bring on the compressor the coils at 39 generally right about now is when it would bring it on We set the control at five the that's the normal setting. There it is. Just came on at 39 So now we're gonna see what it drops down to Factory tells you to pull the fans out and then stick a thermometer in the center of the Coil there and see what it kicks out at Generally, that's around 17 18 degrees. We can look it up to see exactly which one it is But what can happen is when the thing gets low on refrigerant is it'll get down somewhere into the 20s, but not quite down low enough into the teens where it was shut off at and this is one of the starter methods that true tells you to use To find out whether or not it's charged correctly or not So before I go tapping into it and disturbing the refrigerant charge I'd like to see whether or not it's that or if it's a thermostat issue Really low down in there, and it just doesn't shut off Look at that right off at 15. Gotta love it when things work correctly when you get there I'm gonna say the thermostats prior issue Fan blades and stuff are a little bit yucky Grills aren't too bad. We'll clean them anyhow and Checking to see which thermostat that takes I have the electronic one on my truck Looks like the fan motors are starting to lose oil. That's not good. Got them all cleaned up Everything's looking pretty good there Yeah, both those Quite a bit of oil on them Yeah, definitely quite a bit of oil on them I'm gonna recommend they change them leave that up to them. Let's make the decision All right, went ahead and pulled out the thermostat It's an 83 1932 There's your 89 1932 all it over 40 degree cut in 18 degree cut out All this stuff can be found at true manufacturing comm Just go there and look it up download it You can pretty much print all this different stuff for the different books Make yourself up a book make it nice and easy The retro kit here is the one that's called for It shut off a little bit lower than 18 so we're gonna go ahead and change this out Refrigerant wise it appears to be working fine So the kind of thing left in is the thermostat So we'll go ahead and get that changed this one here Senses coil temperature to come on and box temperature shut off. So it's the best of both worlds All right, well, we got this down. I'm gonna go ahead and scan it for gas leaks and I'm gonna clean off this coil. All right, I got 120 volts there black wire The pink wire with black stripe is my power wire coming into my control the white one there Obviously, it's my neutral. I tapped in up there use their three piece connector Then you want to make sure that that doesn't break when you close the door So by pushing that in and the power's still there. We know we're good and then we've got the temperature sensor mounted right There so it's gonna pull the air right across it But it's running I got it in place ahead of time and then fed it through the backside of this Makes it a little easier than try to put it in place and hook it up The pointy thing was on bottom before now. It's on top You have no choice because of the way it's placed in there. The body of that is too big Bring in the Wire there through the evaporator wire tight in place and then this here I'm gonna wire tie these all up and make them look a little bit nicer. Just like that right there So we'll just put her back up and we should be pretty much ready to go Everything's back together. All the grills are in everything's cleaned up there. We've got our thermistor here We're gonna sit there and watch and see how the temperature it shuts off at so we're gonna plug it in and let it get started We've already checked me for all the fan blades. Do not hit anything. Give it a little while and see what we get All right, it just shut off right at about 30 and It won't come back on till it hits about 38 to 40 degrees area Product temperature will maintain the safe limits there And we should be good to go. I Just check to see if there's any relays down below and there is none sometimes those can stick on you But other than that, I mean You see it's already jumping right back up so it overshoots just a little bit on purpose And then like I said, it's gonna control it off the evaporator temperature If you liked the video, please like share and subscribe.
