@@EverythingHVACR I believe it is space temperature control but it may be discharge air not 100% sure but it's controlled by Siemens and has no TD7 display so I couldn't really see the contractor laptop. It's a no control unit from the factory.

@ gotcha, if it’s no controls it could be doing anything but if using KCC/trane controls they typically are controlling discharge temperature.

@@EverythingHVACR Yes sir I went back in November of 2023.

@ it has changed a lot, maybe I’ll see you there some time. More hands on and controls.

@@EverythingHVACR oh yeah we definitely may run across each other one day in the field!

@@baylifehvac991 appreciate it brother! 🙏🏽

@@michaeldarrow6021 No sir not a ton lol

@@MrApplied I am I work for Trane

@ awesome man looks like a blast

@MrApplied oh yeah definitely!

@deavonsanchez3084 yep one of the txvs failed shut. Bulb lost its charge.

@cjshvacjourney4034 how many years you got, and wya

@@deavonsanchez3084 I have about 5 1/2 years in the field

scroll plates have have fallen apart

@xraybravo7180 Honestly I'm no expert especially on meggers but I think you should be able to see at least 40 Mega ohms to ground with a good meter such as a fluke to determine a problem. I pretty much pull out the megger to see if it is taking the voltage I apply to it for a motor or Compressor. I could be wrong but the ones I have tested were not taking the voltages I applied to them were failed because I try to always make a comparison.

Yep that Schrader shot out like a bullet I meant to take a picture.

@@cjshvacjourney4034 wow that's insane

Amen that would have definitely put a hole in my eye! Thank God it didn't!

You cannot once that hole is in it you have to repair if you can if not replace the coil.

Nope it's under nitrogen for the pressure test before the vacuum.

the schrader valve down below the coil shot up into coil and put hole in coil he had to braze shut.

@@ranger178 wow that would suck. Did it do this while you was messing with the valve or something?

​@@jacobhendrickson8935I was trying to replace a leaking discharge line Schrader on a preventative maintenance and had trouble removing it because my tool didn't seem to want to grab it so I removed the part that grabs the Schrader and valved it off. Put a rag on top of the tool while slightly purging and I thought I had the Schrader break free and I removed the rag and opened it little by little and saw on liquid coming out and thought I was good and turns out the Schrader was still in and blew into the coil.

@@cjshvacjourney4034would attaching another core tool to the core tool and keeping the second closed be a safer way?

​@yinggamer7762 Yes that would definitely be safer i didn't think of that.

Nope once that coil blows it's over you can start recovering refrigerant like I did to prevent it from venting into the atmosphere. I got about 37lbs out but I just put virgin refrigerant back in

Ahhhh ok, that sucks man sorry that happened to you but at least you got it going again. Good luck and keep on posting!

It wouldn't come out with the tool so I valved it off with a rag on top and cracked it. Thought I heard the schrader blow off so I valved it off removed the rag began cracking it and only saw liquid coming out and opened it a little more and it shot out like a bullet.

Damn punctured the condenser above it. Literally a bullet.

@@diegopa9980 1. Refrigerant recovery 2. Un-braze old compressor/ liquid line filter drier. 3. Install new liquid line filter drier/ compressor. 4. Pressure test for leaks. 5. Pull deep vacuum and verify it holds. 6. Charge system with refrigerant and verify proper operation. There are much more things involved but this is the basics

The neutral wire was loose inside one of the electrical boxes.

@@Hvacnc I've never used the supco personally but this one has multiple functions and has treated me well. My coworker purchased this one when his supco failed and he seems to like it as well.
