Microwave Turntable Woes: The Surprising Cause of That Irritating Noise
What To Know
- The coupler, which connects the turntable motor to the turntable shaft, can become loose or damaged.
- In some cases, the noise may be caused by a faulty microwave circuitry, such as a malfunctioning relay or capacitor.
- If none of the above solutions resolve the noise issue, it is recommended to contact a qualified microwave repair technician.
A humming microwave turntable can be a puzzling and annoying problem. While it may seem like a minor issue, it can indicate underlying problems that need to be addressed. In this comprehensive guide, we will delve into the various reasons why your microwave turntable might be making noise and provide step-by-step solutions to restore its quiet operation.
Causes of Microwave Turntable Noise
1. Worn or Damaged Roller Guide:
The roller guide, a small wheel that supports the turntable, can wear out over time or become damaged. When this happens, it can create friction and noise as the turntable rotates.
2. Malfunctioning Turntable Motor:
The turntable motor is responsible for rotating the turntable. If the motor is malfunctioning, it can produce unusual noises, such as a grinding or buzzing sound.
3. Obstructed Turntable Shaft:
The turntable shaft, which connects the turntable to the motor, can become obstructed by food particles or debris. This obstruction can cause the turntable to rotate unevenly and create noise.
4. Misaligned Turntable:
If the turntable is not properly aligned, it can rub against the microwave’s interior, causing noise.
5. Loose or Damaged Coupler:
The coupler, which connects the turntable motor to the turntable shaft, can become loose or damaged. This can result in a rattling or clunking sound.
6. Bearing Failure:
The bearings that support the turntable can fail over time, leading to friction and noise.
7. Faulty Microwave Circuitry:
In some cases, the noise may be caused by a faulty microwave circuitry, such as a malfunctioning relay or capacitor.
Troubleshooting and Solutions
1. Check the Roller Guide:
Inspect the roller guide for any visible wear or damage. If it is worn or damaged, it should be replaced.
2. Test the Turntable Motor:
Disconnect the microwave from the power source and manually rotate the turntable. If it rotates smoothly without noise, the motor is likely functioning properly.
3. Clean the Turntable Shaft:
Remove the turntable and clean the shaft with a damp cloth. Remove any food particles or debris that may be obstructing the shaft.
4. Align the Turntable:
Make sure the turntable is properly seated and aligned with the microwave’s interior. Adjust the turntable as needed to eliminate any rubbing.
5. Tighten the Coupler:
Check the coupler for any looseness. If it is loose, tighten it securely. If the coupler is damaged, it should be replaced.
6. Replace the Bearings:
If the bearings are faulty, they should be replaced. This is a more complex repair that may require the assistance of a qualified technician.
7. Contact a Microwave Repair Technician:
If none of the above solutions resolve the noise issue, it is recommended to contact a qualified microwave repair technician. They can diagnose the problem and perform the necessary repairs.
