When your Brown oven self-clean not working, the self-cleaning cycle may not start, may stop early, or may leave the door locked after cleaning. The most likely cause is a faulty touchpad. When you press the self-clean button, the door lock indicator should light and you should hear the lock motor running. If neither happens, the touchpad may need replacement. If the cycle finishes but the door will not unlock, check the door lock motor and switch assembly. A failed temperature control thermostat can also prevent the cleaning cycle from regulating heat, even when the oven bakes and broils normally. Next, inspect the door latch, since a damaged latch or failed microswitch can keep the cycle from starting. Less commonly, a defective oven control board may fail to send voltage to the heating circuits. Disconnect power before testing or replacing parts, and follow your owner's manual when accessing the door lock. Enter your Brown range, stove, or oven model number to find the exact replacement touchpad, door lock assembly, thermostat, latch, or control board for your appliance.
01 - Brown 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 - Brown 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 - Brown 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.
