The door alarm on the fridge started going off the other night, even though the doors are all closed, ice/water dispenser will no longer dispense, however the light in the fridge seems to come on and off correctly when i push the door switches down, although the last couple of tries have resulted in about 50/50 for the interior lights on or not. When i shut off power and restart, i am able to manually disable the door alarm, but eventually it somehow turns itself back on and starts alarming again. Fridge and freezer seem to be cooling normally, dispenser beeps when you attempt to operate it and nothing comes out. Was thinking about replacing door switch first, but in the event that is not the issue, is it more likely to be the L.V. or H.V. control board? or something else?

Thanks,
Joe
