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 timing and execution of oven functions are controlled by the electronic oven control board. It has a digital clock on the front of its housing and is usually in the control console. If the electronic control board doesn't light up when it's supplied with electrical power, or if it doesn't send enough power to the bake or broil element, 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.
Time required: 45 minutes.
You would need the following tools: 1/4-inch nut driver, phillips screwdriver, screwdriver, slot screwdriver, work gloves.
