HUMMING NOISE

 

 

Humming noise coming from refrigerator?

 

 

Reason

 

A humming noise or buzzing or hissing sound can be heard coming from the refrigerator when the

compressor is in operation.


Heat is generated when compressor operates so the fan will also
rotate to cool down the compressor

resulting in this humming noise.

 

 

Troubleshooting

 

The sound can normally be heard when the refrigerator is operating.

When set temperature is met, the motor will stop. 
When the inside temperature rises, the motor will start again.

For screeching metallic noise or tinny clanking noise made by the fan, contact LG Customer Service.

 

 

The sound is normal as fan rotates to cool down the compressor.

  - The sound may also stem from linear compressor operation.

 

 

Operation noise from LG Electronics proprietary linear compressor is 20dB (dead room).
