Rita T Lincoln City , OR August 28, 2018 Appliance: Samsung Refrigerator RS2545SH/XAA Samsung Refrigerator Rs2545sh/Xaa / : Samsung refrigerator would not get cold due to defrosting element not cycling on/off (freezer ok). How to replace Evaporator Assembly. I found a defective Thermal Fuse (open). I also replaced the Heating Element since I had the unit opened up. Its a challenge lacing in a replacement element but with patience it can be done. Its too bad the Heating Element is not sold separately. The refrigerator has been cold for 96 hours and our family is very happy! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
