I had a saturday night service call on a walk in freezer not working, the call went south and I had to open up a supply house and replace the compressor.

    Sorry but this video is over 2 years old and I've just now seen it but what's with the condenser's trying to cool using air inside a closed system or cabinet. The only air in is from what you call a swamp cooler and that air exits a small opening at the other end of the cabinet. To me this is a most stupid idea for an air conditioner unit. To me a condenser needs cool free flowing air change the hot liquid to a hot gas. Is that an old style unit?? When you first opened those access panels I was shocked to see how it was built.

  2. mibars says:

    So this thing swamp cools the air and then that wet cold air in turn cools those small condensers, but it rejects heat back into that box instead of outside of it? Wouldn't it work better if heat was rejected outside?

  3. Benz Lev says:

    Maybe you could've unstuck the compressor by changing the direction (2phases)..and a question-do you solder the king valve with the o ring on?! We put the o ring after everything cools..

    Hey man, great video but quick question: how worth it is that digit manifold you got?
    My hvacr classes start up in a few months and I gotta buy my supplies, so i'm torn on getting the cheaper analog gauges or going high and getting those fieldpieces. Any help appreciated and God bless

    The freezer cond unit never had a low pressure cut off? So the t-stat once satisfied. Would just shut off without pump down? Also, perhaps the restriction in the suction line would not bring in enough cold vapor and that contributed to the overheating issue. Just food for thought.

  6. Nunya Business says:

    Must be nice working on the old stuff, bet the evaporator has an old fashioned mechanical def. timer with a three wire klixon feeding def. htrs. and def. termination, and fans fed from another klixon when coils get cold enough. Bet you love the new computer controlled stuff that you gotta pull out the manual to see how to turn the POS on !

  7. ejonesss says:

    that plastic disk could be a restrictor designed to balance the flow.

    maybe the compressor is too big for the job so the disk was placed in the system to cut down the flow to mimic a smaller compressor.

    it is like the reason that small 2 cycle engines for bikes and scooters has that banana shaped exhaust pipe because small 2 cycle engines require a certain amount of back pressure to run properly

    You could have tried switching your phase power lines feeding compressor. worth trying! What would have been the worst that could had happened? Like the way you explain what you are doing!
