Abstract
A microwave oven is provided with a cooking cavity and an access door. The oven has a food temperature control system for monitoring the internal temperature of food being heated in the oven, and turning off the microwave power at the completion of a heating cycle, or for holding a predetermined temperature for a timed cycle. A temperature-sensing probe is adapted to be inserted into the food. The probe is equipped with a flexible electric cable that is joined to one wall of the cooking cavity for connecting the probe in a control circuit for the microwave generator. This flexible cable is provided with a plurality of diameter-increasing protrusions so, in the event the cable extends outwardly of the cooking cavity, the oven door may not be closed.
