ABSTRACT:
A method for detecting a fire in a microwave oven heating cavity by sensing the time dependent "in-situ" humidity and the temperature environmental conditions of a microwave oven heating cavity in a microwave oven. The humidity sensor and the temperature sensor connect to a programmable controller in the microwave oven. When the sensed "in-situ" relative humidity decreases and the sensed temperature increases within a predetermined time interval, there is a fire in the cavity. The programmable controller processing the sampled humidity and temperature signal information turns off the microwave oven upon sensing the decreasing humidity and increasing temperature within the predetermined time interval indicating a fire.
