hi can i get the full model number please?
are any of the bottons responding?
are you still there?
are you getting any response to the control panel?
what would most likely cause this problem is that the foil that the buttons are mounted to is defective. The control module "reads" the buttons that are pushed by the fact that the resistance between two pins on the circuitboard becomes zero ie. your pushing the button shorts out two pins. the foil could have moistire damage or the resiistance of the tracks could be too high. Solution for both would be to replace the control panel button foil.
do this first .try taking off the cover to the circuit panel behind the control panel.... there will be a couple of holes behind the circuit board which is held in by a couple of screws you shouldnt have to disconect any of the connections just move the board to the side.. spray moisture free canned air in the two holes
ok great,do you have any other questions for me?
try a blow dryer first,then the spray moisture
that would be it]
good luck to you
