Hi guys,
I have been out to a Daewoo American style side by side fridge ffreezer, model FRS 2411. The compressor had failed. From the internet I found the original Daewoo pot details. It was a LBP RSCR 10cc displacement on R134a of course. From my local shop I got the best I could. A 'Unite Hermetique LBP CSIR with 12cc displacement (I always like to over engineer whenever space permits). Anyway, I have fitted it, vacced it charged it and run it. And I am not happy with it at all. I stayed with it for maybe 45 minutes after starting up, and during that time it tripped on the klixon several times, staying off about two minutes each time (manual type klixon). This to me indicates that it is going off on current rather than pot temperature, but I can't think why. The only thing that crosses my mind is the pipe size differences. In the case of the discharge the new pot has a 1/4" stub, and my system pipe is 3/16", and the same on the suction side. Pot 5/16", pipe actual 1/4". So does anyone think this is causing a restriction to the point where the compressor can't get the compressed refrigerant out of the chamber fast enough, and the motor doesn't like it... ? It's all I can think of. Your comments would be really appreciated, many thanks.
