Make sure the electronic sensors or not blocked they should have a clear shot from on side of the ice bin to the other. If they are not blocked replace them.
My icemaker on my whirlpool model # GS6NBERY 01 is not working. I have replaced the ice maker with a new one, but it is still not working. I manually put water into the unit and have tried to jumper the thing to trigger the harvest cycle, but not luck. I suspect the circuit board, but was wondering if anyone had any other ideas.
