Claim 0:
1. A method for heating a compressor when the compressor is off, the compressor having a motor including a rotor and a stator, and a control assembly operably coupled to the compressor, the method comprising the steps of:
applying an initial current to the compressor motor when the compressor is off;
measuring a voltage across the compressor motor and determining a resistance of the compressor motor based on the initial current and a measured voltage, the determined resistance corresponding to a temperature of the compressor;
determining whether the determined resistance is less than or equal to a desired resistance, the desired resistance corresponding to a desired temperature; and
applying a secondary current to the compressor motor if the temperature is less than or equal to the desired temperature.
