If your Gibson oven self clean is not working, the touchpad is the most likely cause, especially if the self-clean button does not light up and you do not hear the door lock motor running. A faulty touchpad may need replacement. If the cycle starts but the oven door will not unlock afterward, the door lock motor and switch assembly may be defective. The temperature control thermostat is another possible cause because it regulates the heating circuit during self-cleaning and can work normally for baking or broiling while failing during cleaning. A damaged door latch or faulty latch microswitch can also prevent the cycle from starting because the oven must lock the door before self-cleaning begins. Less commonly, a defective oven control board may fail to send voltage to the bake and broil circuits. For self cleaning oven troubleshooting, inspect the latch and test its continuity with a multimeter when appropriate, and follow your owner's manual before removing panels or unlocking the door. Enter your Gibson oven's model number to find the exact replacement touchpad, door lock assembly, thermostat, latch, or control board for your appliance.
01 - Gibson 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 - Gibson 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 - Gibson 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.
