I tried to (unsuccessfully) repair my GE Profile fridge myself and was surprised to find some great details on how to do it in one of the appliance repair forums.
I had ice build up on top of the freezer door. According to the advise, I replaced the defrost timer and defrost thermostat. Tried adjusting temp and then thoughts of how long am I going to fight my dying 12 year old fridge started building up. Can't really afford a new one now so I persevered.
None of the solutions from the forum helped and I decided to turn to pros.
Airflow technician fixed it: after I replaced the gaskets ordered directly from GE Replacements 2 years ago they appeared to be defective. No ice build up so far after Airflow guy replaced them!!
