Recently we were called out to a whirlpool microwave job in the San Tan Vistas community in Queen Creek. The problem with the unit was everything worked but it would not heat. Microwaves can be a bit hazardous to work on if your not careful. Inside of these units they carry a capacitor that holds up to 2000 volts of electricity. Always be careful to discharge the capacitor before attempting to perform a repair on your own. With this customer’s unit the problem was the magnetron shorted out. Most microwaves will have this problem when they do not heat. We replaced the magnetron and diode and problem solved. If your microwave is not heating give us a call for a free phone estimate at (602) 412-3133.
