When troubleshooting, you need a multimeter to measure electrical voltages, a nut driver to remove the range back panels, and a Phillips screwdriver if you plan on disassembling parts for testing.

Start by taking out the range from the cabinet by unplugging it first. Be sure to turn off your gas range if it is a gas range.

Step 2: Remove the panels

Using the screwdriver, remove the back panels on top and bottom.

Step 3: Check the wiring connections

Ensure the wiring connections between the oven door lock assembly and the control board are good. Any damaged or loose wires should be mended or reconnected.

If you follow all the above-mentioned steps, most likely, the error will not appear again.
