Ray F Carpentersville , IL April 04, 2016 Appliance: Samsung Refrigerator RM255BARB/XAA Samsung Refrigerator Rm255barb/Xaa: Fan noise. How to replace Refrigerator Evaporator Fan Motor. I replaced the evap fan motor assembly after thawing out the evaporator. I replaced the evap motor assembly because i damaged it while defrosting the evaporator. Too much heat warped the fan blade and bracket. I replaced the motor because of the abnormal load it was put under when it was making all the noise from trying to spin through the ice buildup on the evaporator. This was all done on the fridge side. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
