So it runs about 105 deg and the evaporator is covered in frost/water. Trouble is the compressor gets really hot and kicks out (I assume there is a thermal switch). I put a mechanical timer on it and tried 1/2hr on 1/2hr off and it still gets hot, even kicked out on one of the on times. Is the charge off? I never cracked the system and it has no valves so I don't know the pressures. The suction line is cool about halfway back to the compressor. I haven't messed with these types of compressors much but I do a lot of automotive a/c and when they are properly charged the suction is cold all the way to the compressor and even half the compressor is cold...
