Ge WB27X10011 Microwave Capacitor OEM Part

Wife let me know the microwave was making grinding noise while I was in garage fixing her car starter, never a dull moment. Further questioning she also said it wan't heating the food. Due to being an odd sized built in $$ unit I had to have repaired. I was getting quotes in the $4-500 range for just the magnetron. I was pretty confident the magnetron was the issue and also ordered a new capacitor and diode since I was going to be in there and a lot of money ahead repairing myself. About 15 screws on the unit's sheet metal case with a cordless drill to remove & I had complete access to the internals. A little daunting shorting the capacitor prior to digging in for the repair, the unit sat for about a week and the internal capacitor's resistor must have discharged the capacitor since it didn't even spark when I crossed the terminals. NOTE: do not trust the capacitor will self discharge as designed incase it too is faulty, they still need to be manually discharged, if you absorb the voltage it may be the last thing you do. 6 screws removed the plastic shroud over the magnetron as well as a bracket that holds the capacitor. There were 4 harnesses to unplug and 4 nuts holding in the magnetron. It was pretty simple and designed for servicing. GE had a 10 year warranty on the magnetron I believe and typical GE product it was 10 years old and just out of warranty. I ordered parts at 4:00 p/m on a Thursday and Fedex delivered them the next day at 9:30 a/m. I will be ordering more parts from AppliancePartsPros.com in the future if I need them, all GE OEM parts, great pricing and delivered Jimmie Johns fast!

NOTE: The Microwave stopped during use with a popping sound 1. Replaced fuse (Main Voltage line fuse not the HVT Fuse). 2. Pressed Start and it blew again. 3. Contacted Appliance Parts Pros because the trouble shooting said to check door switches. 4. Checked switches and found all OK but the monitor switch seemed to drag on response time and appeared to have some signs of overheating on connection blades. 5. Ordered and replaced switch. Still blowing fuses. 6. The manufacture's troubleshooting stated that next step was to replace the HVT ($150)! 7. Pulled the HV Capacitor following ALL safety precautions. 8. Tested the capacitor with a Digital Meter and found an internal short. 9. Contacted Appliance Pros Parts and discussed my findings and agreed that my findings were correct and sent me the replacement capacitor ($55). They also asked if wanted to return the monitor switch. I elected to keep that one that I installed because it was a little fasted in it's designed function and I felt that I may be checking one that was about to give up the ghost. So the new one stayed.

Installed replacement Magnetron

I watched "appliancepartspros" videos on You Tube and followed the recommendations. On three occasions in the past 6 years I have needed to repair our microwave when it failed to heat. In all situations it was either the magnetron, capacitor, high-voltage diode, or a failure of the high-voltage diode terminal screw to make a good circuit with the microwave frame. ( I keep photo files of repairs for appliances, plumbing, etc. that I may need to revisit again to speed-up possible future repairs.)

Ordered a new Diode, Capacitor, and Magnetron. I think only the diode was bad, but I chose to replace all these components anyway. After 14 years, I thought it was prudent. Note: I would have been done in 60-90 minutes, but forgot to take a pic of wiring from transformer, etc. Had to figure it out and it took a couple hours longer due to my haste.
