Door latch or switch issue – some models will not operate properly if the switch fails.
Power supply problem – breaker or wiring issue can affect oven operation.

Most Common Fix: Check the Control Board and Power Supply

If your oven will not turn on at all or will not respond correctly, the control board and incoming power are two of the first things to inspect. A failed board or missing voltage can stop the appliance from operating.
