Capacitor High Voltage
Genuine Ge part
By: Ge
Part Number: WB27X11033

The Capacitor High Voltage is an OEM part for GE microwaves. It stores and releases high voltage electrical energy to power the magnetron, which generates the microwaves for cooking.

Over time, capacitors can deteriorate due to prolonged exposure to high voltage, excessive heat, or electrical surges. A malfunctioning capacitor can lead to inefficient cooking or complete failure of the microwave.

Symptoms of a bad capacitor include:

  • The microwave not heating food properly
  • A loud humming or buzzing noise during operation
  • The microwave shutting down unexpectedly
  • Visible damage or leakage from the capacitor

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

Do-It-Yourself Stories from Customers like You Microwave would power on, but no heat.   Mike P. • Monument , CO • April 29, 2022

I took the advice of another buyer and replaced the magnetron, capacitor, and diode from my microwave (make sure you discharge the capacitor). It was not a problem at all to do, I did find an excellent video on YouTube on how to test all of these components and almost anything else in a microwave. It’s called Microwave Oven Troubleshooting in Minutes- Step by Step by electronicsNmore. It was the best thing I watched. Turns out my magnetron was the only thing that was bad and it’s the most...

Do-It-Yourself Stories from Customers like You Ge monogram zmc1095sf02 microwave   Christopher L. • Saint Charles , IL • December 15, 2014

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

High-Voltage Capacitor (Microwave)
Genuine Ge part
By: Ge
Part Number: WB27X11031

This is the microwave's high-voltage capacitor. It stores and releases energy in the high-voltage circuit to power the magnetron so food heats. A failed capacitor can cause no heat, loud humming, or blown fuses.

  • Works with the high-voltage transformer and diode to supply the magnetron with operating voltage
  • Stores and smooths high-voltage DC in the microwave's power circuit
  • Failure may result in no heat while lights and turntable still run
  • Can cause loud buzzing, sparking, or a burning smell during operation
  • May open the internal fuse or trip a breaker when the cycle starts
What's included: 1 high-voltage capacitor Install notes:
  • Unplug the appliance; capacitors can retain a dangerous charge—properly discharge the capacitor before servicing
  • Photograph wire routing; transfer leads one at a time and secure the capacitor firmly in its bracket

Do-It-Yourself Stories from Customers like You Microwave oven was not heating   Scott S. • Charlotte , NC • June 20, 2017

I ordered the capacitor, diode, and magnetron in hopes that I would be able to complete the repair using the less expensive parts. I first removed the oven from the wall and then I removed the metal housing to access the internal parts. I discharged the capacitor using a pair of insulated needle nose pliers. Then I changed out the diode and the capacitor and reassembled the unit and tested it. It still did not heat so I disassembled the unit again and replaced the magnetron this time.... 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 Microwave blowing fuse for Magnetron / high voltage circuit (humming noise prior to fuse opening).   Keith G. • Houston , TX • April 27, 2020

Main Fuse did not open, only fuse for high voltage section was opened. Prior to the fuse blowing a louder than normal hum was heard from microwave for 1-2 seconds prior. Easy fix is the high voltage capacitor, so first checked the voltage across the capacitor terminals to ensure capacitor was discharged. Typically should be reasonably discharged within 30sec-1min assuming drain resistor is still in place. Removed the high voltage cap, and checked the capacitance and did not get a reading....
