After determining it was the motor-evap freezer fan motor that was causing the problem I was able to quickly locate the part on appliancepartspros.com's website and place an order for a replacement part. The part came within a few days as expected and was installed without any problems. The quality of the new part was excellent, even better than the original after doing a side by side comparison. Its been a very good buying experience and I'll be using appliancepartspros.com for future appliance repair orders.
