ABSTRACT:
A microwave oven includes an electric heater disposed in the cooking chamber for cooking by radiant heat. A temperature sensor senses a temperature of the heater, and a door sensor senses an open state of the oven door. If the oven door is open, and the heater temperature is at or above a reference temperature (i.e., a temperature which could burn a user), an alarm, such as an audio and/or visual alarm, is activated to warn the user.
