ABSTRACT:
In a high frequency cooking apparatus including a magnetron, a fan motor, turntable motor, a plurality of relays for controlling them and a microcomputer controlling the relays, the microcomputer is provided with a relay test program. The relay test program is executed when specific two cooking menu selecting keys are simultaneously depressed. Consequently, pulses are sequentially supplied to all the relays and simultaneously, relay identification marks are sequentially displayed on a display unit. Based on the mechanical operation sound from each relay and the displayed content, an operator determines whether or not each relay is normal.
