PURPOSE: A method of reducing hold power is provided to isolate power in a standby state and to supply the power to a slave from a master in action. CONSTITUTION: During a stroke for running a refrigerator, a master microcomputer(200) outputs an electricity control signal to a switch(230) to keep the refrigerator turned on. To stop running the refrigerator, the master microcomputer(200) does not output a signal for stopping driving a slave microcomputer(210) and a sub-board through a wire(10), but an electricity control signal to the switch(230) to turn off the refrigerator. Thereby, the slave microcomputer(210) and the sub-board are stopped by electricity isolation.
