Hi
I have the same problem with my Hotpoint frost free FFA74 light coming on once or twice a day and cracking noise at the back , this for the past 2/3 months. I have taken the plastic tray at the back just above the refrigerating liquid canister which seems very hot . This tray was full of slimy dark pieces so I have cleaned it thoroughly I have as well introduced plastic straws attached together in the two holes going down to the tray (one has a black pipe at the end and the other is just a little hole coming from the fridge above the tray) this seemed to have improved the problem for 48 hours no more and today i am back to square one... red light on then i press the fast freeze and tomorrow will be the same.
I have as well some ice forming in the bottom of the freezer. One thing I have noticed is that the indicator green/OK inside the fridge becomes black which seems to suggest that the fridge upper part gets too hot??? May be this melt some ice in the back of the first (from the top) drawer in the freezer part.
Any other suggestion welcome.
Fab.
