Zusammenfassung:	PURPOSE:To detect a compressor operation by a commercial power source circuit and an overload at a compressor operating time by an inverter by one detector by mounting an overload detector between the compressor and a switching relay. CONSTITUTION:An overload detector 8 is mounted between a compressor 2 and a switching relay 7, and the output is input to a refrigerator controller 4. If the compressor 2 becomes an overload state at a compressor operation time by a commercial power source 1 and compressor operating time by a controller 4, a control signal is input to the controller 4 by the detector 8, a triac 3 is turned OFF or an inverter 5 is stopped.
