Hi thanks for the question.
Can you hear the fan going in the freezer, Is this the noise you hear.
Turn it off and take the freezer panel off to see if its not all iced up .
If its iced up the problem is a no defrost problem,
Let me know what you find.
Here is the fan motor you have to replace and a breakdown .
The panel has to come off to get at the fan motor.
It should be just behind the ice maker .
that panel probably with a plastic shield.
I know sometimes it takes time to resolve the problem with a part.
Some times we can fix it on the spot.
.Good luck with that
