To specify failed temperature sensor and heater when the temperature sensor and the heater for heating a plurality of placing sections for placing food and keeping them at a set temperature respectively fail.
For the temperature control of the respective placing sections, the detected values of the temperature sensors of the respective placing sections are inputted to a control circuit. The control circuit judges that the temperature sensor failed when the detected value of the temperature sensor is abnormal and judges that the heater of the placing section whose temperature is detected by the temperature sensor failed when the detected temperature of the temperature sensor is abnormal further. Then, the lamp of the failed placing section among the lamps 44-61 of an operation panel 37 is made to flicker and a failed part is displayed at an error display device 68 by a code.
