John H Semi Valley , CA July 09, 2018 Appliance: General Electric General Electric GFSF2HCYHWW Ge Refrigerator Gfsf2hcyhww: Main board failure. How to replace Refrigerator Main Control Board. Since this has happened on two other occasions I decided to fix it myself. I replaced the main board but I still need to replace the evaporator motor. The motor is the most likely cause for the board failures. GE technicians are worthless and never fully eliminated the problem so thanks to Appliance Parts Pros I can do it myself! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
