ABSTRACT:
An electric cooking oven for use a normal cooking mode and defrost mode is provided which comprises a detector for detecting a temperature of a food body during cooking thereof, the detector comprising a thermistor which detachably attached to the food body to sense the temperature thereof. A circuit is provided for compensating the gradient of the output characteristics of the temperature detector to increase the gradient of the output characteristic curve of the resistance of the thermistor as a function of temperature in when the thermistor is operating in a temperature range in which it has a low accuracy of temperature sensing.
