The Surprising Reason Why Your Microwave Is Making A Noise On The Turntable

Microwaves are a quintessential part of modern kitchens, offering convenience and speed in food preparation. However, when your microwave starts making noise on the turntable, it can be a cause for concern. This blog post delves into the various reasons why your microwave may be making noise on the turntable and provides comprehensive troubleshooting solutions to resolve the issue effectively.

Causes of Microwave Noise on the Turntable

1. Worn-out Roller Guide

The roller guide, located under the turntable, facilitates its smooth rotation. Over time, wear and tear can cause the roller guide to become damaged or loose, leading to excessive noise.

2. Misaligned Turntable

Proper alignment of the turntable is crucial for smooth operation. If the turntable is misaligned, it can rub against the microwave’s interior, causing noise.

3. Food Debris Accumulation

Food particles or other debris can accumulate under the turntable, interfering with its rotation and generating noise.

4. Faulty Motor

The motor drives the turntable’s rotation. A faulty motor can cause the turntable to move erratically or make grinding noises.

5. Loose Drive Coupling

The drive coupling connects the motor to the turntable. A loose coupling can result in slippage, causing noise and reduced turntable speed.

6. Worn-out Turntable Bearing

The turntable bearing supports the weight of the turntable and allows it to rotate smoothly. A worn-out bearing can lead to noise and difficulty in rotating the turntable.

7. Foreign Objects

Occasionally, foreign objects can get lodged under the turntable or in the motor housing, causing noise and potential damage.

Troubleshooting Solutions

1. Inspect and Clean the Roller Guide

Remove the turntable and check the roller guide for damage or wear. If necessary, replace the roller guide with a new one. Clean any debris that may have accumulated under the turntable.

2. Realign the Turntable

Ensure that the turntable is properly seated on the roller guide. If it is misaligned, adjust it carefully until it fits snugly.

3. Remove Food Debris

Clean the area under the turntable thoroughly to remove any food particles or debris that may be causing interference.

4. Test the Motor

Disconnect the microwave from the power outlet and remove the turntable. Manually rotate the motor shaft to check for any resistance or grinding noises. If the motor is faulty, it may need to be replaced.

5. Tighten the Drive Coupling

Inspect the drive coupling and ensure it is properly tightened. A loose coupling can be tightened using a wrench or screwdriver.

6. Replace the Turntable Bearing

If the turntable bearing is worn out, it may need to be replaced. This requires disassembling the microwave, which should only be attempted by qualified individuals.

7. Remove Foreign Objects

Carefully inspect the microwave for any foreign objects that may have become lodged under the turntable or in the motor housing. Remove any objects you find to eliminate potential noise sources.

Additional Tips

• Regularly clean the microwave, including the turntable and roller guide, to prevent debris buildup.
• Avoid overloading the microwave with heavy or unevenly distributed items.
• Use a microwave-safe turntable cover to protect the turntable from food splatters and debris.
• If the noise persists despite troubleshooting, contact a qualified appliance repair technician for professional assistance.
