Ge WB27X10073 Capacitor (Microwave High-Voltage) OEM Part

I ordered the capacitor, diode, and magnetron in hopes that I would be able to complete the repair using the less expensive parts. I first removed the oven from the wall and then I removed the metal housing to access the internal parts. I discharged the capacitor using a pair of insulated needle nose pliers. Then I changed out the diode and the capacitor and reassembled the unit and tested it. It still did not heat so I disassembled the unit again and replaced the magnetron this time. Reassembled the unit and tested it and this time it worked. With the excellent 365 day policy from Appliance Pro Parts you can return the unneeded parts.

First I tried replacing the fuse (located waaaaay back and near the top of the housing, accessible by releasing the control panel), but a new one blew immediately when the microwave was tested. The next suggested step was to check the capacitor, which required that the combo oven be removed from the cabinet to access several removable metal panels and shrouds (shut the power to the appliance off at the breaker panel) which must be removed to access the capacitor. I used a pair of insulated needle-nose pliers to short the capacitor before removing it, and got no spark. The multimeter showed an internal short in the capacitor (zero resistance both ways), so I ordered a new capacitor and two fuses. Once they arrived, I installed the new capacitor and swapped in a new fuse, replaced the shrouds, and tested the microwave, which works again! (The turntable drive is dodgy, but that’s another problem for another day...)

Wife pushed start, microwave buzzed and went completely dead. Knew from sound that the problem was on high power side of device so ordered electrolytic cap and rectifier diode along with fuses. Parts shipped same day as order. I received parts 6 days later and fixed microwave portion within about 1-1.5 hours. I have used AppliancePartsPros.com before and appreciate good service and all the support on site.
