CRANKCASE HEATER CONTROL FOR HERMETIC REFRIGERANT COMPRESSORS Abstract Of The Disclosure The temperature is sensed at the compressor, indoor coil and outdoors. The sensed temperatures are compared and if the compressor temperature is not a specified amount higher than the lower of the other two sensed temperatures, then the crankcase heater is energized. When the compressor temperature rises to or is a specified amount above the lower of the other two temperatures, the crankcase heater is deenergized.
