Customer Repair Stories

Replaced the capacitor. Microwave worked for a few days and then lost heat.

Replaced the diode next to the capacitor. If you replace a capacitor, replace the diode while your in there so you don't have to disassemble and reassemble twice.

Microwave Would Not Heat Up

Unfortunately for us, it wasn't the diode that needed to be replaced. The instructions that were given on how to discharge the capacitor before working on the diode, magnatron or capacitor itself, was very helpful. You don't need to be and electrician if you can follow directions. Ours ended up being the magnatron. It took about 15 minutes to swirch out. I had to buy yhe part thru another site, because it was $40. 00 Dollars cheaper and the part was here in one day. Thanks for the information on the repair.
