Hi and thank you for choosing Just Answer. I am Tech Michael and I will be assisting you today. Please be patient as these are technical questions that may require a bit of conversation to solve. Also remember to be detailed in your description of the problem. That will help me make a diagnosis quickly for you. The sound you are hearing has to do with the circulating fan behind the wall inside the freezer. Please check something for me so I can be sure of the cause. Open the freezer door and inspect the rear wall inside the freezer, let me know if there is any heavy frost or ice build up on that wall inside there.
Also may I have the full model #?
Thank you Tech Michael
I have found the problem thank you. I had filled one of the freezer drawers too full and a piece of packaging was hitting the fan at the back of the freezer. Re-stocked the drawer properly. No noise!!!!
