The Magnetron is an OEM component specifically designed for GE microwaves. The magnetron is responsible for generating microwave radiation that cooks food by utilizing electromagnetic energy. It works by accelerating electrons within a vacuum tube using a magnet to generate microwave emissions. 

Causes of a bad magnetron can include overuse, excessive cooking times, damage from arcing due to sparks, or general wear and tear over time. 

Symptoms of a bad magnetron include:

  • Inefficient or inconsistent cooking and heating 
  • Longer cook times required 
  • Food not cooking thoroughly or remaining cold in spots
  • The microwave making buzzing or humming noises during use

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

Questions & Answers

For Ge Magnetron (Part Number: OEM20666037)

1 Answer

Hello Rick, The magnetron for the model provided is WB26X32629 and is in stock. I'm sorry but as per the manufacturer, there is no conclusive test for the magnetron to determine if it is good or not unless the magnetron tube is burned, which indicates a failure.

Hello Don. MAGNETRON REPLACEMENT 1. Discharge capacitor. 2. Disconnect magnetron leads. 3. Remove 3 screws securing the magnetron. 4. Removed the magnetron assembly until the tube is clear from the waveguide. When replacing the Magnetron, be certain that RF gasket is in place and mounting screws tight. Failure to do so could result in hazardous levels of microwave leakage. Perform microwave leakage test.

Hello Terry. The magnetron wattage is based on the wattage of the microwave it's installed into. Based on the model number you provided, the magnetron WB26X32629 in the microwave is 1100 watts. Hope this helps.

Peter for Model Number JVM1631CJ01

Hi. It appears that I need to replace the magnetron and diode in my GE Spacemaker JVM1631CJ01. Some instructions that I found on the internet say that upon replacement, the "stirrer" needs to be replaced at the same time. It also says that I should be able to get a kit with the magnetron, diode, and the stirrer assembly for this model. Do you sell anything like that? I notice that the stirrer assembly doesn't even have numbers in the diagram - is that because it comes in a kit with another part? Any info would be greatly appreciated. Thanks!

Hellp Peter! It does not seem that your model has a stirrer. There is not kit available for the parts you are speaking of. For the magnetron use part number and for the diode WB26X32629 use part number WB27X10037. Thanks!
