The circuit controls an opitimal toast heating time, senses a ΔV from optic sensor, and detects an initial temperature of food by a temperature, humidity sensors. The circuit includes a temperature sensing means (11) which senses an initial temperature in a grill range heating room (23), a humidity sensing means (12) which senses a humidity, an optic sensing means (13) which detects color a variation of food, and a control means (10) which controls an output of heater (14) by a specified voltage (ΔV).
