Abstract
A control circuit for a refrigerator combined with a microwave oven includes signal delay selecting and comparing circuitry start sensing circuitry timer circuitry and load driving circuitry in order to properly control operations of the refrigerator and the microwave oven. The control circuit eliminates unnecessary delay time of the operation of the microwave oven during operation of the refrigerator, and makes the refrigerator operate after start-up of the microwave oven is completed.
