When the new bulb didn't want to go in, I felt around and realized the base of the old bulb was still in there. With some effort I got it out and new bulb in, Light cover fit fine, but did not come with a screw to hold it in. That would have been helpful. Read more

Capacitor (Magnetron)
Genuine Whirlpool part
By: Whirlpool
Part Number: W10850446

This magnetron capacitor is the microwave high-voltage capacitor that helps supply the magnetron with the pulse of energy needed to produce heat. Replacing a failing capacitor restores normal heating performance and reduces arcing or loud humming. What it does

  • Stores and releases the high-voltage pulse required by the magnetron so the microwave can generate heat.
  • Prevents unstable magnetron operation that can cause weak or no heating.
  • Common symptoms of a failing capacitor: oven runs but doesn't heat, intermittent heating, loud buzzing/humming, or visible arcing inside the cavity.
  • A failed capacitor can also cause blown internal fuses or tripped circuits.
What's included
  • One capacitor.
Install notes
  • Disconnect power and verify the appliance is completely de-energized before servicing.
  • Capacitors can hold dangerous charge; discharge the capacitor safely with an insulated tool.
  • Use the exact replacement part and follow the appliance service manual for routing and connections.

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 Magnetron   Todd P. • Greeley , CO • April 29, 2022

I researched the problem. Found the solution online and ordered parts from AppliancePartsPros.com. It only took a screwdriver to make the repair. The only confusion I had is my model of microwave had a double diode, and the one sent to me (by model number) was a single diode. I wasn't sure what to do, either install the new single one or put the old double unit in. I went with the new single diode, and it works fine. I don't know why the two differences, but it all worked out. Read more
