My icemaker stopped making ice a few days ago I've switched power leads between the water dispenser and the icemaker at the fill valve on the back of the fridge icemaker fills with water when I hit the water dispense at the door,the photo eye setup flashes twice then pauses and repeats when I open the door anybody know if that's normal? or whatother test I can do to narrow down the problem between the icemaker or the boards thanks
