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.
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.
Shut off the power and gas
Pull the range forward and plug it. Someone can assist you when moving the range. For a dual-fuel range, shut off the gas supply. If you want to prevent scratching the flooring, set the range on cardboard.
Remove the lower back panel
Press the panel against the range so it doesn't fall as you remove the last couple of screws. Place the panel on the floor and then lower it.
Disconnect the relay control board
If you want to attach the wires to the new control board correctly, you have to take a picture of the wires and mark them with numbered pieces of masking tape. The wires need to be disconnected from the relay control board.
Remove the relay control board
The back wall of the oven has mounting screws for the relay control board. The mounting clips hold the relay control board in place. The board should be removed and discarded safely.
Install the new relay control board
To prevent static discharge damage to the control board, ground yourself against the metal frame of the range. To lock the mounting clips in place, position it on them and push it inward. Put the mounting screws in and tighten them. If you want to discharge static electricity that could damage the control board, wear a grounding strap or ground yourself by touching the metal frame of the range.
Reconnect the wires
Follow your digital image or numbered tags to connect the wires to the relay control board. It's important that wires are connected correctly to the new relay control board to prevent damage to range components and serious injury. If you don't know how to connect the wires, you should have a service technician do it.
Reattach the back panel
Place the upper back panel on the back of the range so that the mounting holes line up. Attach the back panel to the range with the mounting screws.
Turn on the gas and power
The gas supply should be turned on. Push the range into position by plugging it in. 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, phillips screwdriver, screwdriver, slot screwdriver, work gloves.
