Door open message stays on - GE JE1640 Microwave Oven

I'd look for a defective relay or shorted triac on the control panel circuit board. Either could cause this problem.

On a few new model microwave ovens, this is a "feature"! It's purpose is to cool the microwave parts down, and to remind you that your food is cooked.

What usually breaks is the door open lever, but sometimes there's just a grease buildup around the door open button.

On a counter top model, the outer cover will need to be removed to diagnose and repair this. On an over-the-range model, only the control panel needs to be removed.

Please unplug the oven first.
