I bought the replacement fan and blade from Parts pro, along with a new ice maker. Figured the evap fan motor was failing with all the noise it was making. Nope. Once I took the cover off and examined the situation, realized all I had to do was push the existing fan blade back on the shaft, away from the fan motor, and problem fixed. So I didn't need the parts after all. Still used the ice maker, but cost $14.95 to return the fan motor and blade. That was all unnecessary. Oh well, live and learn. All nice and quiet again. You should try this first b4 you order any replacement parts. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
