I am attempting to troubleshoot a defrost problem on a GE Profile Side-by-side. I downloaded a repair manual from the site, but it isn't my exact model. My model number is GSS22SGPA SS. I can jumper the output connector on the motherboard and cause the defrost heater to heat. I suspected the motherboard, and replaced it. After a few weeks, the problem re-appeared. I metered the evap thermistor, and it seems OK, with the resistance changing when I warm it with my hand or apply ice to it. My problem is tracing the leads back to the connector on the motherboard. The wire colors and pin numbers on my prints do not match what I have. I have also attempted to use the diagnostic procedure with the temp control buttons, but the manual refers to a "hold" button which I don't seem to have. I feel I could troubleshoot the problem if I had the correct manual or information. Any help would be GREATLY appreciated.

Check for air leaks in the door seal and the flap in the ice dispenser.

You can’t enter the diagnostic mode unless your refrigerator has a control with more than four buttons.

Check ohms on the thermistor at the main board to eliminate a loose or broken wire between the board and the thermistor.

If you have a service manual for any side-by-side GE electronic refrigerator the pin numbers on the board for thermistors will be the same.
