Freezer Humming/Buzzing

This issue may be too broad to even diagnose, but I wondered if this might be something commonly diagnosed.

We bought a Whirlpool freezer new a couple of years ago & its always had a light hum or buzz to it occasionally. I am sure its only when the motor or compressor is running but I notice it more sometimes than others. This morning, I could easily hear it across the kitchen. It was really kinda annoying this morning.
I just went back for a 2nd cup of coffee & its quiet as a mouse.

What normally humms/buzzes in a freezer when running & is it something easily fixed or is it a problem that needs to be serviced under warranty?

Any relevant input is appreciated.

It is probably the compressor that you are hearing. It is a sealed unit so there isn't anything you can do.

As PilotDane said it is probably the compressor.
You did not give a model number so cannot say if there is anything else in the unit that could buzz.

Compressors are usually mounted on rubber feet so tightening or loosening them may help.
Also check that none of the tubing is au against something else causing a buzz.

If the unit uses a relay type start device then the relay may be the cause.
