Matt B Minneapolis , MN January 03, 2026 Appliance: General Electric Refrigerator PFS22SISASS Ge Refrigerator Pfs22sisass: Display panel intermittently not working sss error sometimes sporadic cooling door open alarm when doors closed. How to replace Part Core Refund. I had previously replaced the controller board so I was familiar with the process. Unplug the fridge, removed the panel, took a photo of the existing board and connections, disconnected ground wire and cable connections, removed the board, installed the new board, connected cable connections, attached the ground wire, closed the panel access. Verified the wire removal per instructions in the compressor compartment, plugged in, all was working. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
