Opened up the back of the freezer compartment to locate the evaporator fan motor.
It was determined that the fan blade was unbalanced due to the fact that it had been hitting the wiring and had worn off part of the blades. The Grommets looked a little worn also.
As a side note, I had to replace the fan motor as well.
Totally surprised, ordered parts on Nov.10 and received parts on Nov. 11
