The fridge side works fine, the issue is with the freezer. The freezer gets warm so the ice in the icemaker melts and leaks all over the place.
I do not know if this is under warranty, my serial# is FH433510.
HELP!
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air.
check defrost heater, defrost thermostat.Your defrost thermostat could also be letting the heater stay on too long.

If the coils are iced up and the heater and defrost thermostat are ok the problem is the motherboard Part 801 on your diagram. http://www.appliancepartspros.com/sect/g/1/k/g1kwb2bemp.gif
I don’t know about your warranty except the sealed system has a five year warranty.
