PURPOSE: An insulating structure of an insulation control circuit is provided to divide insulators installed at various places to a main microcomputer and to a sub-microcomputer and to solve the problem of safety of a user by installing insulator to the divided positions. CONSTITUTION: An insulating circuit of a refrigerator is composed of a rectifying part(21) and a leveling condenser(C), an inverter(22), a position sensing part(31), a sub-microcomputer(24), a main microcomputer(25), a voltage detecting part(28), a current detecting part(29), an inverter controlling part(27), a power supply device(20) for controlling and insulators(S21,S22). Herein, the current and the voltage supplied to a motor and the inverter controlling the motor is recognized by analog value. And the controlling becomes easy.
