I have plastic pieces coming out of my ice bin.
Answer Hello George. You will need to replace the ice bin assembly on the unit.
cross reference to whirlpool ,need ice -control looks like your # AP3873956.Shaft is turning,will rotate with no ice in bin,put ice in and will not turn,coupler look ok and tight.
Check to make sure that the auger in the ice bin is turning and if it is turning but will not turn and the motor does not turn but sounds kind of jumpy or just hums then the motor would be the issue as opposed to the ice container.
On the ice-contnr I need to take mine apart to see what parts I need to order but I can't get the screw out of the bottom
It may be necessary to use an extraction tool to remove the screw and replace the screw if you are unable to remove the screw with a Phillips screw driver.
