Abstract
A method for controlling the temperature of a 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; measuring a voltage across the compressor motor and determining a resistance of the compressor motor based on the initial current and a measured voltage; determining whether the determined resistance is less than or equal to a desired resistance; applying a secondary current to the compressor motor if the determined resistance is less than or equal to the desired resistance.
