Rick D Salinas , CA December 09, 2021 Appliance: Model KSSO48FTXO3 Refrigerator would not stay on. Replaced the main circuit board, evaporator fan motor, and power supply. Probably did not need to change the power supply but did so just to be safe. Replaced the fan motor because I was advised it could be the cause of the circuit board failure. Got a rebuilt main circuit from Circuit Board Medic because new ones are no longer available. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
