When your oven self-cleaning cycle is not working, the touchpad is the most likely cause, especially if the door lock indicator does not light and you do not hear the lock motor running when you press the self-clean button. A faulty door lock motor and switch assembly can also prevent the cycle from starting or keep the oven door locked after cleaning. Other possible causes include a temperature control thermostat that works during baking and broiling but fails during self-cleaning, a damaged door latch or latch microswitch that cannot confirm the door is locked, or a defective oven control board. The control board uses relays to send voltage to the bake and broil circuits, heating components, and other self-clean functions, so a failure can stop the cycle. These are common oven self clean problems, but always disconnect power before inspecting or testing parts, and follow your owner's manual before attempting to unlock the door. Enter your range, stove, or oven model number to find the exact replacement touchpad, door lock assembly, thermostat, door latch, or control board for your appliance.
01 - 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 - 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 - 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.
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.
