I have the same issue. Makes ice but won't dump unless I hit the reset button. got the refridge in 2016 nov (LFX28968ST). I checked water flow, temp of freezer is 4F to -2F. the filter is origonal but water comes out fast of water dispensor and to fill the ice tray. Did a sensor check and it says EMPTY so it's working. Hesitant to call for service and pay 100 for that plus parts. Must be one of the switches or computer parts so I'd rather buy a new one for 1899 and get all new stuff instead of fixing a 7 year old unit. First problem I had with this refridge/freezer. Heard horror stories with several brands from family/friends. Oh well, it's only money.
