I have an bottom freezer ge profile 18 cubic ft. I think it's a 2003 model no sure.
Basic problem: fridge stops blowing cold air into the fridge. Noticed that the fan still spins in back even though no cold air in the fridge. Pulled fridge out and found that the coolant line that runs down the back freezes at the point where it enters the refrigerator. The line is partially insulated with blk foam. Used a hairdryer to thaw frozen point and fridge started to work again. Two days later same problem, line freeze.
Thermostat?
OK, I think I understand. Thing is we need to do a few things to see if your control board is the problem or if the fan or a freon leak is the answer. You need to tell me if this began suddenly or if over a period of time. I have been having trouble lately from Fixya if the customer (YOU) responds to my solutions. Let me know if you want my help and I will see if I get a email letting me know of your response, Thanks, Sea Breeze
Here is where to look for control board. Part number WR55X10656
and number 801 in picture below.

Most all functions are controlled by this board if yours is the model number PSS26MSRASS

We need to first unplug and examine both sides of the board for burs, signs of heat or loose solder connections. If your refrigerator has lost freon here is what to look for. Unplug and remove the rear panel in the back of the freezer. Just a few minutes after you unplugged you will see ice on part of the evaporator and cold sweat on the other part. You need to tell me the answer to what you see to go to next step. Let me know. Sea Breeze
Check for burn marks on both sides of board.
Only if the internal fan stops or lack of freon will cause the tube to freeze back to the compressor. If low on freon and the suction line pulls air into the sealed system will this happen. Evaporator fan not blowing air over the evaporator or defrost not taking place will cause freeze back. And all of this could be related to the control board. If I have helped you in any way or if you need more help let me know, please rate me. Thank You Sea Breeze

This happened suddenly.
Thawed line again, but internal fan did not turn on at all this time. Observed line starting to freeze back to the compressor again. Just to clarify, the motherboard is behind the large rear panel and not in the compressor area right?
