I have an amanna Side by side.
I don;t know a whole lot about refrigeration, but I do know a good bit.
The defrost timer does work.
The compressor runs when the thermostat ask it to. But I am totally comfused about this. My sister gave it to me, it was my nephews. It did not cool when I got it. I checked the freon 134a, and it was out, I filled it and it started freezing, worked great, like a new one for two week straigh sitting on my front porch, I bring it inside and two days later it quite, the compressor still runs, get warm, but it don't cool at all. and it did not loose it's freon. The pressure on the low side never changes when it run or off, cooling or not. It there something wrong in the pump in the compressor?
I really want it to work but don't want to put a lot of money in it, other than that everthing else work fine and look like it was purchased yesterday.
Sincerely Chris
