I am working on a CME656AE-32(A-I THINK) and havin nuthin but trouble with the thing.
I have done a serious clean on it, removed the C.F.M. and cleaned the coil and checked the refrigeration. This thing will run and make ice for a while and then will trip out on a solid refrigeration light. After resetting it it may run another few hours before tripping out again!
After going through a lot of headache with the tech support guys he said I have a bad expansion valve. He asked me to give him the superheat...more accurately he asked for the suction pressure and then the temp at the txv bulb (38psig and 43*)which was a 5 superheat; does anyone know what the superheat is supposed to be on these machines?
Oh yeah, he thought at first it was a thermistor so he had me check the temp at the sensor...I had 153-155*, he didn't act like that was out of line too bad but gave me an uneasy feeling with hes responce...is that an alright temp?
