The part(s) or condition(s) listed below for the symptom Oven not self-cleaning are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
During the oven's self-cleaning cycle, the door lock switch activates the door lock motor to prevent the oven door from being opened. If the door lock motor and switch assembly is defective, the oven door will not unlock once the self-cleaning cycle is complete. On most ovens, you can open the oven door by removing certain screws or panels. Check your owner's manual for further instructions.
The oven control board has relays that send voltage to the bake and broil circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components.
The thermal fuse is a safety feature that protects the oven from overheating. If the oven gets too hot, the thermal fuse trips to shut off power to the oven. The thermal fuse is not resettable—if the thermal fuse blows, you must replace it. To determine if the thermal fuse has blower, use a multimeter to test it for continuity. If the thermal fuse does not have continuity, replace it.
