Tim B Arroyo Grande , CA October 22, 2015 Refrigerator side of the unit kept freezing the food Technician replaced the damper first, but that did not fix the problem. Then he said it was the circuit board that needed replacing after confirming the temp sensor was ok, but he wanted $200 in labor to replace it. The same part from Appliance Parts was $75 cheaper and I was able to replace the part myself in about 20 minutes. Saving an additional $200. Everything works just like it was supposed to. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
