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

Do-It-Yourself Stories from Customers like You Broken grill vent & cut power cord on microwave   Karl B. • Goshen , KY • April 24, 2019

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.

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
