My GE Profile bottom freezer has an IM4A icemaker, it's been replaced twice because the icemaker doesn't appear shut off (it doesn't have the metal arm) and the guardrail (paddle-like arm) then sweeps the ice out of the bucket and onto the freezer floor. I've been advised its a design issue, but friends have an identical icemaker and they have had no problems. Any ideas as to how to stop this from happening?
