Question and Answers

Q:

I have a model 401.8934991 Microwave Oven. What could cause it to come on by itself?

A:

The touchpad or the control board could cause the microwave to come on by itself. You need to get a technician to diagnose and repair the microwave. If it runs very long with nothing inside the oven it will ruin the magnetron and maybe some other parts.
