Bobby S Little Rock , AR November 20, 2017 The freezer side of my side by side was icing up causing the ice box side to not get cold. I replaced the Defrost Heater and the Defrost Timer and that seem to have solve the problems. I found the video instruction on how to change these parts and advice from the Appliance Pro Technicians to be extremely helpful. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
