Genuine Ge part
By: Ge
Part Number: WB24X829

Do-It-Yourself Stories from Customers like You Ge microwave ran when turned off if door was shut   Jason A. • Cary , NC • April 02, 2017

The first symptom was our microwave would continue to run after the time was up. The light would go out, the turn table would stop but you could still hear the microwave running and whatever was in it would continue to cook. The only way to stop it was to open the door. It was intermittent at first but eventually it would always run no matter what as long as the door was closed. Several other posts referenced these switches as the problem. I just replaced both and problem gone. It turns out... Read more

Do-It-Yourself Stories from Customers like You Installing replacement light bulb sockets (wb08x10016) on my ge microwave (jvm1440bd003)   Peter W. • Chesterfield , VA • March 17, 2025

I recently tackled a repair on my GE microwave (model JVM1440BD003, manufactured in 2003) to replace the light bulb sockets for the under-microwave lights. Since one socket was failing, I decided to replace both at the same time to avoid future issues. I used two WB08X10016 light sockets, which are the correct OEM parts for this model. The process started off smoothly thanks to a helpful installation video on the website. It made the job look straightforward: remove five screws to drop the... Read more

Do-It-Yourself Stories from Customers like You Convert microwave from recycling vent to an external vent system   Gaspar D. • Summerfield , NC • December 31, 2015

We followed the manufacturer's instructions about re-positioning the fan motor and installing the vent damper (easy). We constructed a duct system from the microwave to the outside of the house (challenging). We used 3.25" x 10" metal duct to start the system through the wall behind the microwave, where we added framing to reinforce a cut stud. We ran the duct up a closet wall and through its ceiling into the attic. We had to make an offset duct piece from 3.25" x 10" metal duct to clear a... Read more

This is a 25 year old built-in over-the-range appliance. Only previous problem was 1 failed door switch (of 3 total), replaced 2 years ago.

Do-It-Yourself Stories from Customers like You Broken handle on microwave   Stephen K. • Gilbert , AZ • August 29, 2015

My particular model of microwave had one screw visible but the other hidden behind a plastic ring. I needed to pop the ring out by disengaging the plastics clips using a putty knife; then it was an easy job of unscrewing the old handle and screwing the new one in. It probably took me just as long to write this description as it did to actually replace the handle. Read more

By: Ge
Part Number: WB27X10170

  • Reduces stress on motor windings that can lead to premature failure when functioning properly
What's included:
  • One motor capacitor
Install notes:
  • Always disconnect power at the breaker or unplug the appliance before servicing
  • Capacitors can hold a charge; discharge safely
  • Observe proper polarity and mounting location during installation; secure wiring and connectors
