New to the site, Have an approximate 8 year old GE Proflie Performance fridge side by side, freezer compartment gets iced up- bad and the compressor keeps running and fridge wont get below 60. while freezer stays around 50
I read several replies on icing refridgerators about checking and replacing the defrost timer, the defrost heater, defrost thermostat and possibly the control board.

For this model TFS22PPDABS GE Profile Performance the defrost timer appears to eb the same as the fridge control knob, I see no way to turn the shaft with a flat bladed screwdriver and checking 10 mins later for a sizzle. I also cannto find the control board or the heating unit, it must be behind the ice maker unit.
I called a technician in who wanted over 400$ to replace the defrosting system but he recommended a new fridge since the compressor may go next due to the extra stress. I see all these parts for the defrost system sells for about 50$.
Should I just replace this unit (as one piece) and see what happens ? I am handy with a screwdriver but the diagram/instructions seem sketchy considering it does not dismantle easy. Any help or advice is appreciated.
Thanks
