What To Know
- Replacing a magnetron is a relatively simple task that can be completed in about an hour.
- Connect the wires to the magnetron, making sure the terminals match the original configuration.
- Place the outer casing back on the microwave and secure it with the screws.
If your LG microwave has stopped heating, it’s likely due to a faulty magnetron. Replacing a magnetron is a relatively simple task that can be completed in about an hour. Here’s a comprehensive guide to help you through the process:
Safety First
Before starting, ensure the microwave is unplugged from the power outlet. Wait for the capacitor to discharge by shorting the terminals with an insulated screwdriver.
Gathering Tools and Materials
You’ll need the following tools and materials:
- Phillips screwdriver
- Flathead screwdriver or putty knife
- New magnetron (compatible with your LG microwave model)
- Electrical tape
Removing the Outer Casing
1. Remove the screws holding the outer casing in place.
2. Carefully lift the casing away from the microwave.
Accessing the Magnetron
1. Locate the magnetron, which is usually a round, metal component with a high-voltage capacitor attached.
2. Disconnect the wires connected to the magnetron. Use a flathead screwdriver or putty knife to gently pry the connectors apart.
3. Remove the mounting bolts holding the magnetron in place.
Removing the Faulty Magnetron
1. Carefully lift the faulty magnetron out of the microwave.
2. Inspect the magnetron for any damage, such as cracks or burns.
Installing the New Magnetron
1. Align the new magnetron with the mounting holes.
2. Tighten the mounting bolts securely.
3. Connect the wires to the magnetron, making sure the terminals match the original configuration.
4. Wrap electrical tape around the wire connections for added insulation.
Reassembling the Microwave
1. Place the outer casing back on the microwave and secure it with the screws.
2. Reconnect the power cord to the microwave.
Testing the Microwave
1. Place a cup of water in the microwave.
2. Set the microwave to high power for 1-2 minutes.
3. Check if the water is heating up. If it is, the magnetron has been successfully replaced.
Troubleshooting
If the microwave is still not heating after replacing the magnetron, check the following:
- The power cord is securely plugged into the outlet.
- The door is closed properly.
- The microwave is set to the correct power level.
- The magnetron is compatible with your LG microwave model.
Recommendations
Replacing an LG microwave magnetron is a straightforward task that can be completed with basic tools and materials. By following these steps, you can restore your microwave to its full functionality and enjoy delicious, heated meals once again.
