The compressor had a direct electric short, it ruined the digital, temperature control, once I got it running then I found that the expansion valve was bad.

    it always stinks to have to tell the customer something else is wrong but some components are unknown without a working compressor there's just nothing you can do hopefully they understand!

  3. Randy Kocian says:

    Yea, it's frustrating when you have to tell the customer that more needs done and the cost will be more. But, like you said, if you look around lots of things contribute to why the cooler's not yet running. You nailed it Jim. Poor design. Money is tighter and customers dont want to spend it. Multiple failures before they'll call. It all adds up to a bigger bill.

    Jim! Another Good & Interesting video! You mention in your video you working on a Walk in Cooler? Your Testo 550 Showing 24.4 psi. Equal a Evaporator Temp. of -9.9 deg. That would be close to charging a walk in freezer? Instead of a walk in Cooler????? 31.57 of the video.

    let's say for example a got here a 2 HP hvac reciprocating compressor and it's only i have, but I need to change a 2 HP reciprocating refrigeration compressor, so can i use that hvac compressor?same HP ,and same reciprocating compressor ,the only difference is for refrigeration / and for airconditioning? so please answer?

  6. R K says:

    Didn't you know that the POE oil in the compressor is highly hygroscopic and by exposing it to the air humidity will cause acid formation? No. You probably didn't.
    I
    can't see you using nitrogen for brazing. Am I right?

    32:46 'My compressor is running very hot. That's because the superheat is so high. Not getting refrigerant coming back to cool the compressor…'
    Really? So where is all the refrigerant going then?

    You have no idea what you are doing.

  7. roberto cervantes jr says:

    I have a four door cooler that I'm going to give away, but the compressor/condenser unit that is hooked up to it works and has the refrigerant in it. Is there a way I can shut off or a valve that I can shut off before cutting the line so the refrigerant don't leak out? Or does the refrigerant need to be drained from the tank?

  8. derek obidowski says:

    i don't like the newer cases they are now charged with a flammable refrigerant even auto air conditioners if there is a burnout in the hermetic compressor whats the risk of it blowing up. as True and other mfgs went to flammable refrigerant like R-1234yf and so on.
