just got used GE profile performance Model # tfx30pb or pp has both on tag. Seemed to work ok while viewing it at sellers home. He stated that it had been working fine until DF code came on, Full of meat so just purchased a new unit. Cleaned coil, plugged in and it was working fine, had frozen water in freezer and cold bottled water in frig. Well needless to say after a couple of days in DF came back on, Back of freezer has then coat of frost, warm temp light is on and ff code is flashing. Can unplug for several hrs. and plug back in but not long before symptoms lights are back on. Is there any on-line repair manual out there and anyone who can give me some advice on repairs needed. I have tools to check electrical but not refrigerant. Not sure how to access areas need to get to ( defrost timer, defrost heater, valve, and so on).
Am THANKFUL for any help,
