I have a Magic Chef Model: mcwbc77dzc mini wine cooler that will no longer cool after a power outage.
I have verified the following:
Compressor has 120vac going to it.
Compressor is coming on and outputting correct amps.
Compressor fan is on and running
Cooling fins are free from dust
Temp sensor is working. (measured resistance)
Both upper and lower evap fans are on and running.
The compressor is not shutting off and getting very hot because I believe no Freon is flowing to cool the unit. When I first plug it in I hear 3 clicks coming from some kind of relay. This is not the compressor start relay but a different one that has 2 wires going to it directly connected to the MAIN PCB. There is a brass cooling line that is routed through it. It seems to be some kind of pressure valve that must open to allow Freon to flow?
I measured the resistance of this relay and it is showing as kilohms which is why I think it is the problem. The schematic on the back of the fridge just calls this a "valve."
I have no idea what this is called or where I can find one. Can anyone help me?
