LG Microwave - Troubleshooting Loud Noise While Cooking

  • Troubleshooting

At a Glance

During operation, the product may produce vibration noises and sounds may be caused by foreign objects.
If the product is installed on a sink or a rice bin made of metal, noise may occur.

Try This

A microwave oven generates vibration noise of about 45 to 50 decibels (dB) during the process of producing high frequency waves.
The sound is normal, therefore rest assured as it is not a product defect.

If the noise is unusually loud, check the following.

Make sure that the microwave's rotating plate and supporting stand are placed in the correct position. If they are not in the correct position, they may cause interference or instability during rotation, leading to noise.

Rotating dish and rotating tray inside the cooking chamber

If there is any debris on the rotation axis or wheels, it can get stuck and cause noises. Remove any debris beforehand.

Rotating shaft and rotating wheels inside the cooking chamber

If the place of installation is not flat, it may cause noise due to vibration during operation.

Check if there is any uneven movement when pressing one side of the product. If there is movement, move the product to a flat surface to level it.
If a sudden loud noise occurs, a professional service inspection may be required.

This guide was created for all models, so the images or content may be different from your product.
