Microwave High Voltage Capacitor
Genuine Whirlpool part

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 oven door handle   Kari M. • Greensburg , IN • December 10, 2021

The plastic piece on the handle where the screw goes in to hold glass door up had broke. I ordered new handle, the retainer pieces that go over the plastic pieces to lock it all in and screws that were suggested. The screws were the wrong ones. They were way too small. I already had one screw and thankfully only had to buy 1 new one because the screw was $40 and shipping’s $10 for it AND it’s on back order right now. The old retainer ring that goes over plastic piece was a nightmare to remove... Read more
