LG Oven not self-cleaning
When your LG oven self-clean not working, start by checking whether the door lock indicator comes on and whether you hear the door lock motor running when you press the self-clean button. If there is no light or humming sound, the touchpad is the most likely cause and may need replacement. A defective door lock motor and switch assembly can prevent the door from unlocking after the cycle, while a faulty temperature control thermostat may allow baking and broiling but fail during cleaning. The self-clean cycle also will not start if the door latch cannot lock the door, so inspect the latch and test its microswitch for continuity when applicable. If these parts check out, a failed oven control board may not send voltage to the bake and broil circuits. Before testing or replacing parts, disconnect power and follow your LG owner's manual for door-lock procedures. This self-cleaning oven troubleshooting guide can help you identify the problem. Enter your LG range model number to find the exact replacement touchpad, door lock assembly, thermostat, latch, or control board for your appliance.
01 - LG 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 - LG 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 - LG 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.
Highly Likely
04 - LG Range/Stove/Oven Door Latch
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.
Highly Likely
05 - LG 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.
Highly Likely
06 - LG Range/Stove/Oven Control Board
The 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.
