There is provided a door lock control device in a heating cooker that prevents a door from being accidentally unlocked when the door is locked and a temperature inside the heating cooker is a predetermined temperature or more such as during self-cleaning. When the temperature inside the cooker is low and a thermal switch 8 of a lock detection and thermal switch portion 6 is closed, the lock detection and thermal switch portion 6 can be energized, and a power supply line 2 can supply power to a drive motor 5 to lock and unlock the door. In the case of self-cleaning or the like, the door is locked and a detection switch 7 is on a door lock side 7a, but the temperature inside the cooker is high and thus the thermal switch 8 is opened, and the power supply line 2 is interrupted.
