Abstract

A microwave oven and a refrigerator are combined in a single cabinet and share line power supplied to the cabinet. Door interlocks and a manually settable time are provided for disconnecting electrical supply to the compressor of the refrigerator during operation of the magnetron of the microwave oven. The circuitry provided ensures that electrical supply is reconnected to the compressor upon expiration of the timer setting, even if the door of the oven is incidentally left open after use.
