Question and Answers


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


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.
