A combined microwave and electric heating oven comprises a gas sensor disposed in an exhaustion duct for detecting an exhaustion gas concentration, and a thermistor disposed in the exhaustion duct for detecting an exhaustion air temperature. A control circuit is connected to receive output signals derived from the gas sensor and the thermistor for terminating a cooking operation when both of the exhaustion gas concentration and the exhaustion air temperature exceed preseleted reference levels, respectively.
