PURPOSE:To avoid simultaneous start and stop of a fan motor and compressor motor for preventing noises from being combined together by a method wherein the fan motor and the compressor motor are controlled so that they are started and stopped with a specified time lag. CONSTITUTION:The cooling temperature in a freezing compartment detected by a temperature detector 8 is received by a temperature input circuit 11 and compared with the set temperature of a target temperature and when the detected temperature is higher than the set temperature R, a driving instruction is output to a fan motor relay driving circuit 11c to open a relay 13 and start the fan motor 5. After the fan motor 5 is started, the operation time of the fan motor 5 is counted. When a specified operation time elapses, a driving instruction is output to a compressor motor relay driving circuit 11d. The relay driving circuit 11d opens a relay 14 and starts a compressor motor 7 according to the driving instruction. |
