What To Know
- If your GE microwave is experiencing issues like sparking, arcing, or a humming noise, it’s possible that the capacitor needs to be replaced.
- Replacing a GE microwave capacitor is a straightforward procedure that can restore your microwave to working order.
- Common signs of a faulty capacitor include sparking, arcing, a humming noise, or the microwave not heating properly.
If your GE microwave is experiencing issues like sparking, arcing, or a humming noise, it’s possible that the capacitor needs to be replaced. Replacing the capacitor is a relatively simple task that can be done in a few steps. In this guide, we’ll walk you through the process of how to replace a GE microwave capacitor.
Materials You’ll Need
- New capacitor (matching the specifications of your microwave)
- Screwdriver (Phillips head)
- Electrical tape
- Multimeter (optional)
Safety Precautions
- Unplug the microwave from the power outlet before starting any work.
- Discharge the capacitor by touching a screwdriver across its terminals.
- Wear gloves and safety glasses for protection.
Step-by-Step Instructions
1. Locate the Capacitor
Open the microwave door and remove the glass tray. The capacitor is typically located at the back of the microwave, near the high-voltage transformer. It’s usually a cylindrical or rectangular component with two terminals.
2. Remove the Capacitor
Using a screwdriver, loosen the screws holding the capacitor in place. Carefully pull out the capacitor by its terminals.
3. Test the Capacitor (Optional)
If you have a multimeter, you can test the capacitor to confirm that it’s faulty. Set the multimeter to capacitance mode and connect the leads to the capacitor terminals. A reading of zero or infinity indicates a faulty capacitor.
4. Install the New Capacitor
Align the new capacitor with the terminals and insert it into the microwave. Secure it with the screws.
5. Insulate the Connections
Wrap electrical tape around the terminals of the capacitor to prevent any accidental contact.
6. Reassemble the Microwave
Replace the glass tray and close the microwave door.
7. Test the Microwave
Plug the microwave back into the power outlet and turn it on. If the capacitor was the issue, the microwave should now operate normally without any sparking or arcing.
Troubleshooting Tips
- If the microwave still isn’t working after replacing the capacitor, check for other potential issues such as a faulty door switch or high-voltage transformer.
- If you’re not comfortable working on electrical appliances, it’s best to contact a qualified appliance repair technician.
Wrapping Up
Replacing a GE microwave capacitor is a straightforward procedure that can restore your microwave to working order. By following these steps carefully and taking the necessary safety precautions, you can safely and effectively complete the repair.
Frequently Asked Questions
