Hi, my name is Farrell & I will be helping you with your problem today. Thank you for using just answer. What has happened to your microwave, is that the hi-voltage section that does the cooking has gone out. PLEASE BE AWARE THAT IF YOU REPAIR YOUR MACHINE, THAT YOU ARE DEALING WITH HI AND LETHAL VOLTAGE. Your unit will have to be taken down off of the wall for repair. Parts you will need:
