I have a similar problem with Whirlpool French door unit, only my water trickles out from under the fridge. Already replaced the ice maker once, now we have to defrost every month to make the unit resume working. Our appliance repair consulted with Whirlpool, which said that it is a known problem and that basically any ice maker in the fridge portion of a unit (as opposed to a side by side) is just going to have problems. Manufacturers haven’t figured out a way to keep them from freezing up because of the temperature differential. Until my unit dies, I’m probably switching to a countertop ice maker.
