What To Know
- If you’re using too many other appliances on the same circuit as your microwave, it can overload the circuit and cause the microwave to hum.
- The humming sound may indicate a potential electrical issue or a damaged component.
- The cost of repairing a humming microwave will vary depending on the underlying cause and the extent of the repair.
Microwaves are essential kitchen appliances that make our lives easier by quickly and conveniently heating food. However, when your GE microwave starts humming, it can be a frustrating and concerning issue. If you’re wondering “why is my GE microwave humming,” this blog post will provide you with comprehensive troubleshooting steps and potential solutions.
Common Causes of Humming in GE Microwaves
- Loose Magnetron: The magnetron is a critical component that generates microwaves. If it becomes loose, it can vibrate and create a humming sound.
- Damaged Capacitor: The capacitor stores electrical energy and helps regulate the magnetron’s operation. A damaged capacitor can cause the magnetron to hum.
- Faulty Diode: The diode allows electricity to flow in one direction only. A faulty diode can disrupt the magnetron’s circuit and lead to humming.
- Overloaded Circuit: If you’re using too many other appliances on the same circuit as your microwave, it can overload the circuit and cause the microwave to hum.
- Dirty Fan: The fan helps circulate air inside the microwave. If it becomes dirty, it can create a humming sound.
- Loose Turntable Motor: The turntable motor rotates the food inside the microwave. If it becomes loose, it can vibrate and hum.
- Loose Components: Other loose components, such as the door latch or microwave housing, can also vibrate and create a humming sound.
Troubleshooting Steps
1. Check the Magnetron:
- Remove the microwave’s outer shell.
- Locate the magnetron, usually at the back of the microwave.
- Ensure the magnetron is securely fastened.
2. Inspect the Capacitor:
- Look for any bulges or leaks in the capacitor.
- If the capacitor is damaged, it needs to be replaced by a qualified technician.
3. Test the Diode:
- Use a multimeter to test the diode.
- If the diode is faulty, it needs to be replaced.
4. Check the Circuit:
- Ensure that no other appliances are using the same circuit as the microwave.
- If possible, try using a different circuit to see if the humming stops.
5. Clean the Fan:
- Remove the fan and clean it with a damp cloth.
- Ensure that the fan blades are not damaged or obstructed.
6. Tighten the Turntable Motor:
- Remove the turntable and locate the turntable motor.
- Tighten any loose screws or bolts.
7. Inspect Loose Components:
- Check for any loose screws or bolts on the door latch, microwave housing, or other components.
- Tighten any loose components securely.
Recommendations: Resolving the Humming Issue
By following these troubleshooting steps, you can identify and resolve the underlying cause of the humming sound in your GE microwave. If the humming persists after trying these steps, it is recommended to contact a qualified appliance repair technician for further assistance.
Questions You May Have
Q: Is it safe to use a microwave that is humming?
A: It is not advisable to use a microwave that is humming excessively. The humming sound may indicate a potential electrical issue or a damaged component.
Q: Can I fix the humming sound in my GE microwave myself?
A: Some basic troubleshooting steps, such as checking loose components or cleaning the fan, can be attempted by homeowners with basic DIY skills. However, for more complex issues, it is recommended to seek professional repair assistance.
Q: How much does it cost to repair a humming microwave?
A: The cost of repairing a humming microwave will vary depending on the underlying cause and the extent of the repair. Minor issues may cost around $50-$100, while more complex repairs can range from $150-$300 or more.
