What To Know
- The magnetron is usually located on the side or back of the microwave cavity.
- Use a screwdriver to loosen the screws holding the magnetron in place.
- Replacing a GE microwave magnetron is a relatively straightforward repair that can be completed in under an hour.
A malfunctioning magnetron can cause your GE microwave to stop heating food. Replacing this essential component is crucial to restoring your microwave’s functionality. This comprehensive guide will walk you through the steps of how to replace a GE microwave magnetron safely and effectively.
Tools and Materials
Before you begin, gather the following tools and materials:
- Screwdriver set (Phillips and flathead)
- Needle-nose pliers
- Replacement magnetron (compatible with your GE microwave model)
- Electrical tape
- Heat-resistant gloves
Safety Precautions
- Unplug the microwave: Always disconnect the microwave from the power outlet before starting any repairs.
- Wear heat-resistant gloves: Microwave magnetrons can retain heat even after the microwave has been turned off. Protect your hands from burns.
- Use caution around capacitors: Capacitors can hold an electrical charge even after the microwave is unplugged. Discharge them by touching a screwdriver across their terminals.
Step-by-Step Instructions
1. Remove the Outer Cover
- Unscrew the screws holding the outer cover in place.
- Carefully remove the outer cover.
2. Locate the Magnetron
- The magnetron is usually located on the side or back of the microwave cavity.
- It is a cylindrical component with a high-voltage wire attached to it.
3. Disconnect the Magnetron
- Use a screwdriver to loosen the screws holding the magnetron in place.
- Gently pull the magnetron out of the cavity.
- Disconnect the high-voltage wire by gently pulling it off the magnetron terminal.
4. Install the Replacement Magnetron
- Align the replacement magnetron with the mounting holes in the cavity.
- Insert the high-voltage wire into the terminal on the magnetron.
- Secure the magnetron with the screws.
5. Replace the Waveguide Cover
- The waveguide cover is located next to the magnetron.
- Remove the screws holding it in place.
- Replace the old waveguide cover with the new one.
6. Reconnect the Microwave
- Plug the microwave back into the power outlet.
- Replace the outer cover and secure it with the screws.
Testing the Microwave
Once you have replaced the magnetron, test the microwave to ensure it is working properly:
- Place a cup of water in the microwave.
- Set the microwave to high power for 30 seconds.
- The water should heat up significantly.
Troubleshooting
If the microwave is still not heating food after replacing the magnetron, try the following:
- Check the high-voltage wire for any damage or loose connections.
- Inspect the waveguide cover for any tears or holes.
- Ensure that the replacement magnetron is compatible with your GE microwave model.
Wrapping Up: Restoring Your Microwave’s Functionality
Replacing a GE microwave magnetron is a relatively straightforward repair that can be completed in under an hour. By following these steps and taking the necessary safety precautions, you can restore your microwave to full functionality and enjoy heated meals again.
