It's possible that the oven door lock assembly has failed and needs to be replaced, if the oven doesn't automatically lock when you start the self-clean cycle or it doesn't open after cooling to room temperature. If the child lock-out doesn't work on an oven that has that feature, you should replace it.
The outer part of the oven door is made of a piece of glass that is heat resistant. The outer door glass panel needs to be replaced.
There is a relay control board in some ranges. The bake element or a surface element can be controlled by electrical relays on the relay board. The relay control board needs to be replaced if it is malfunctioning.
Follow these steps to fix your issue:
Unplug the range
Pull the range forward and then plug it. Someone can help you move the range. To prevent scratching the flooring, put the range on cardboard.
Remove the back panel
Press the panel against the range as you remove the last couple of screws to make sure it doesn't fall. To set the panel aside, lower it to the floor. Before removing the back panel, you might need to loosen the power cord. The Installation Guide shows how to remove the power cord.
Disconnect the wires from the door lock assembly
If you want to attach the wires to the door lock assembly the same way, you need to take a picture of the wires and mark them with numbered pieces of masking tape. The oven door lock motor assembly has wires that need to be disconnected.
Remove the door lock assembly
Attach the door lock assembly to the mounting screws. Pull the oven door lock motor assembly down to release it from the connecting rod. The door lock assembly needs to be removed from the range.
Install the new oven door lock assembly
Put the connecting rod in the opening of the oven door lock motor assembly. Attach the door lock assembly to the assembly.
Reconnect the wires
The digital image or numbered tags show the location of the wires on the oven door lock assembly.
Reattach the back panel
Put the outer back panel on the back of the range so that the holes are in place.
Plug in the range
Push the range into position by plugging in the range. The anti-tip brackets need to be properly engaged in the rear leveling foot.
You would need the following tools:
1/4-inch nut driver, screwdriver, work gloves.
