Range: Oven door won't unlock

If the door won't open when the oven cools down after self-cleaning, or when you try to disable child lock mode or control lock mode, the problem could be with the oven door lock assembly or the electronic control board. First shut off power to the oven and then check the wiring between the electronic control board and the oven door lock assembly. If the wiring is okay, replace the oven door lock assembly. If that does not fix the problem, you might need to replace the electronic control board as well.

These repairs may help solve your Range problem:

Replace the range's oven door lock assembly

If the oven doesn't automatically lock when you start the self-clean cycle, or it it doesn't unlock after cooling to room temperature after a self-clean cycle, it's likely the oven door lock assembly has failed and needs to be replaced. Also replace it if the child lock-out doesn't work on an oven equipped with that feature.

Replace the range electronic oven control board

Electronic oven control board

The electronic oven control (EOC) board governs the timing and execution of oven functions such as baking and broiling. It's usually in the control console and often has a digital clock on the front of its housing. Replace the electronic control board if it doesn't light up when it's supplied with electrical power, if it doesn't operate properly or doesn't properly send voltage to the bake or broil element (in an electric oven) or burner (in a gas oven).
