GE Microwave Error Code LOCKED DOOR

LOCKED DOOR flashes when a self-clean cycle has been selected but the oven door is not properly closed, or when the oven has not yet cooled below the temperature threshold required to safely release the door lock after a clean cycle. It is a safety interlock condition built into the self-clean system. Close the door firmly and restart the cycle, or allow more time for cooling after a completed cycle.

Normal cooking functions should not be attempted while LOCKED DOOR is active, as the condition indicates either an incomplete door seal or an oven that is still at self-clean temperatures. Operating the oven with a door that is not properly latched is a safety hazard. Wait for the condition to resolve before using the appliance.

If the fix is simply closing the door or waiting for the oven to cool, there is no cost involved. If a component like the door latch assembly, door switch, or temperature sensor needs replacement, parts typically range from $20 to $80 depending on the specific component and model. Professional labor for diagnosis and repair can add $75 to $200 or more depending on your location and service provider.

First, confirm the oven door is fully and firmly closed, as even slight misalignment can prevent the latch from engaging. If the message appeared after a self-clean cycle, wait at least 30 to 90 minutes for the oven to cool below the locking temperature threshold before the lock releases. If the message continues after adequate cooling and a confirmed closed door, the door latch assembly or temperature sensor may need inspection and possible replacement.

Resetting the control by unplugging the appliance or cutting power at the breaker may clear the displayed message, but it will not resolve the underlying condition if the door is still open or the oven is still above the locking temperature. If the root cause is not addressed, the message will return when the self-clean cycle is attempted again. A reset is only a lasting fix if the original trigger was a temporary glitch in the control board.
