What To Know
- If this motor fails or becomes weak, it can cause the turntable to wobble or make a grinding noise.

Microwaves are essential kitchen appliances that make our lives easier. However, when they start making loud noises, it can be a cause for concern. In this blog post, we’ll delve into the common reasons behind microwave noise and provide solutions to restore your appliance to its quiet operation.
Common Causes of Microwave Noise
1. Magnetron Failure
The magnetron is the heart of a microwave, generating the microwaves that heat your food. If the magnetron fails or becomes faulty, it can cause a loud humming or buzzing sound. This issue typically requires professional repair or replacement.
2. Worn-Out Fan Motor
The fan motor is responsible for circulating air inside the microwave. Over time, the motor can wear out or become clogged with debris, leading to increased noise levels. Cleaning the motor or replacing it if necessary can resolve this issue.
3. Turntable Motor Problems
The turntable motor rotates the food during the heating process. If this motor fails or becomes weak, it can cause the turntable to wobble or make a grinding noise. Replacing the motor is usually the best solution.
4. Loose or Damaged Stirrer
The stirrer is a metal blade that helps distribute microwaves evenly. If it becomes loose or damaged, it can produce a rattling or banging sound. Tightening the stirrer or replacing it can fix this problem.
5. Oversized or Heavy Food
Placing oversized or heavy food items in the microwave can put excessive strain on the motor and turntable, resulting in loud noises. Ensure that food fits comfortably inside the microwave and isn’t too heavy.
6. Debris or Food Particles
Food particles or debris can get trapped in the microwave and cause rattling or buzzing sounds during operation. Regular cleaning can prevent this issue.
7. Faulty Door Switch
The door switch prevents the microwave from operating when the door is open. If this switch malfunctions, it can cause the microwave to make a clicking or banging sound. Replacing the switch is necessary.
Troubleshooting Tips
- Check for loose parts: Inspect the stirrer, turntable, and door for any loose components. Tighten or replace as needed.
- Clean the microwave: Remove any food particles or debris from the interior and exterior of the microwave, including the fan motor and stirrer.
- Use appropriate cookware: Only use microwave-safe cookware that fits comfortably inside the appliance. Avoid heavy or oversized items.
- Contact a qualified technician: If the noise persists or worsens, it’s best to contact a qualified appliance repair technician for professional assistance.
