Question

letter regarding refrigerator that you brought last year producing a humming sound​

Answer 1

Answer:

The buzzing noise you hear is the sound of the refrigerator compressor running. The noise is normal. You will also hear a noise when the refrigerator compressor starts at the beginning of a cooling cycle and when it shuts off.

It can be also heard after getting water from the door dispenser. The noise should not last longer than 7 seconds.
