Hi, welcome to Just answer
How old is the refrigerator ?
and do you hear a high pitch whistling sound ?
About 3years old and yes it is a high pitched whistle.
OK...the problem is that you likely have a faulty freezer fan motor and which needs to be replaced
however, before replacing that you can try to clean it completely
and see if that solves the problem
Do you mean clean the freezer fan motor?
I mean the fan
