General Electric Diode Or Rectifier

14 year old GE Profile microwave wouldn't heat, but had power. Read reviews here. Ordered triumvirate of magnetron, capacitor, & diode. Was hoping not to need the capacitor as this was an expensive part; and if not needed to return to AppliancePartsPros, which has been SOP. After watching a couple YouTube videos of microwave capacitors being shorted, I made a capacitor discharge tool ordering 24W 100K Ohm resistor and high voltage test wires w/ alligator clips from amazon. At the same time,... Read more

• No heat

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... Read more

Replaced the high voltage diode. You will need a special Torx screwdriver to remove the tamper resistant screws holding the cover. Once the cover is removed there should be a packet inside containing a schematic and detailed troubleshooting instructions. I used extreme caution to discharge the capacitor. The rest was simple. One screw and a push connector to remove and reinstall the diode. I fired it up and it was good as new. Thanks to AppliancepartsPros for the good guidance and extremely... Read more

I replaced both the Magnetron and the high voltage diode. I now have a fully functional microwave. I received the parts on time and the quality was good. I would use appliance parts pro's again. Read more

After testing the power diode and capacitor that drives the magnetron power source, they came up good on the static tests with the multimeter and battery (used for the diode test). And the static test of the magnetron came fine too, ie: passed the ohm resistance test and short to case resistance tests. Still the oven works only heat water to ~137 degrees max even after running for several minutes. I suspected a break in the winding of the magnetron might be opening after it heats up. Try as I...

I went online to specifically check for resolution to problem. I found out the most common problem was a bad magnetron and diode. I then watched a couple youtube videos on the repair process. I entered model # of microwave at the Appliance Parts Pros website and was able to order exact parts. The APP site had excellent schematics for exact location of parts in microwave. I followed those and fixed microwave! The wife was amazed! Read more
