Microwave High Voltage Capacitor
Genuine Whirlpool part
By: Whirlpool
Part Number: W10850446

Microwave not heating or making loud humming noise? The high-voltage capacitor supplies power to the magnetron. DIY repair in under an hour.

Do-It-Yourself Stories from Customers like You My microwave was working at half power   Eric H. • Tonawanda , NY • October 30, 2015

I ordered a new magnetron and a new capacitor and after they arrived I set to work. I took plenty of pictures with my phone to remind me how the components came apart but it was pretty straight forward. Once the new parts were in and everything was reassembled the microwave worked good as new. The repair was less than a third the cost of replacement and no special tools are required. Just be careful to discharge the capacitor. This website is a great resource. Read more

The grill vent is only held in place by two screws. Super simple fix. Remove the two screws and the old grill vent, position the new vent and put the two screws back in. Replacing the cord required that cabinet to be removed. Lots of screws on the back, top and bottom. Once the screws were removed, the cabinet pulled back. The power cord connections were then clearly visible. Undid the two wire connectors and unscrewed the ground wire from the body to remove the old power cable. Installed the... Read more

Do-It-Yourself Stories from Customers like You Microwave wouldn't heat when you took item out after beep it was still cold! all other functions were fine   Jerad S. • Salem , IA • January 03, 2015

Removed unit from wall and took outer shell off, de-energized capacitor and then took a multi-meter and tested all the High voltage parts and magnetron. They tested out fine other than the diode and then I looked at the "Safety" circuit if you will the power loop that goes through door switches and thermostats to energize the High Voltage transformer and magnetron. Turns out the thermostat that is on the side of the magnetron wasn't closed, so I took a butane torch and heated it up past the... Read more
