PROBLEM TO BE SOLVED: To provide a pre-heating control device of a compressor capable of controlling the pre-heating energizing current to the compressor when the supply voltage varies in an air conditioner. SOLUTION: The pre-heating control device has a comparing/judging means for detecting the supply voltage of the compressor 6, comparing the detected supply voltage and a standard voltage, and judging the size of the supply voltage. A drive circuit of the compressor is controlled by a control means 12 based on the result of the judgement and the pre-heating energizing current is adjusted.
