When your KitchenAid oven self-cleaning cycle will not start or complete, the touchpad is the most likely cause. Press the self-clean button and check whether the door-lock indicator lights up and the lock motor makes a low humming sound. If neither happens, replace the touchpad. A defective door lock motor and switch assembly can also keep the door from unlocking after the cycle finishes. If the cycle will not begin, inspect the door latch because the oven must detect a locked door before self-cleaning starts. The latch microswitch should have electrical continuity when tested with a multimeter. Next, consider the temperature control thermostat, which regulates voltage and temperature during cleaning and can fail even when baking and broiling work normally. An oven control board or main control board may also fail to send voltage to the heating circuits. This self-cleaning oven troubleshooting guide can help you identify the faulty part, but always follow your owner's manual before removing panels or unlocking the door. Enter your KitchenAid oven model number to find the exact replacement touchpad, door lock assembly, thermostat, latch, or control board for your appliance.
01 - KitchenAid Range/Stove/Oven Touchpad
The door lock indicator light should come on and you should hear the lock motor running when the self-clean button is pressed. If the indicator light does not come on and you don't hear a low humming noise as the door is being locked, it's likely the oven's touchpad is faulty and will need to be replaced.

02 - KitchenAid Range/Stove/Oven Door Lock Motor and Switch Assembly
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.
03 - KitchenAid Range/Stove/Oven Temperature Control Thermostat
The oven thermostat sends voltage to the heating circuit and regulates the temperature of the oven during the self-cleaning cycle. It is possible for the oven thermostat to function properly for baking and broiling but not for cleaning. Due to its complexity, the oven thermostat is difficult to test. If you suspect the oven thermostat is at fault, replace it.
For your safety, the self-clean cycle will not begin unless the oven door is locked. If the door latch is broken and unable to allow the door to be locked, the self-clean cycle will not begin. Inspect the latch for damage. You can also use a multimeter to test the latch assembly's microswitch, if applicable, to determine if the switch has appropriate electrical continuity. If the latch is damaged or the microswitch tests negative for continuity, the door latch should be replaced.
05 - KitchenAid Range/Stove/Oven Oven Control Board
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.
