Abstract

A control system for a crank case heater (10) for an inverter operated compressor (12) of a cooling system includes a contactor (14) operably connected to the crank case heater and an inverter controller compressor and at least one compressor temperature sensor (24) disposed at the compressor to sense a compressor temperature and an compressor internal temperature sensor. A controller is operably connected to the crank case heater and the at least one compressor temperature sensor and configured to close the contactor to energize the crank case heater independently from operation of the compressor when the at least one compressor temperature sensor senses a compressor temperature below a desired threshold.
