Troubleshooting your Gibson electric range when its 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 range 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.

To diagnose and repair a broken oven door lock, watch our troubleshooting door lock problems on a range video.

Installing a new electronic oven control board in your Gibson electric range

• Pull the range out of the cabinet and unplug the power cord. Use a helper if necessary.
• Remove the screws from the control panel back shield and pull it off the range.
• Disconnect all the wires from the oven control board. Remove the mounting screws and pull the oven control board out of the control panel.
• Position the electronic oven control board and reinstall the mounting screws. Carefully connect all the wires to the new oven control board.
• Place the control panel back shield on the back of the control console and secure the back shield with the mounting screws.
• Plug the power cord into the electrical outlet. Carefully slide the range back into the cabinet, ensuring that the rear leveling foot properly engages with the anti-tip bracket so the range doesn’t fall forward when you open the oven door and pull out a loaded oven rack. Use a helper if necessary.
