Ice maker won't stop producing ice, even when bucket is full.

The control module has failed on the ice maker. You can replace the control module alone, but I would replace the ice maker completely.
Here is a link for the control module.
Here is a link for the new ice maker.

Ice maker will not dump ice, makes it but will not dump ice.

Hi,
Here is a tip that I wrote about the reasons why ice makers do not work.

Ice Maker Problems and Ice Maker Troubleshooting

could be your ice maker or your water valve

On the ice makers on refridgerators unless the ice in the bucket is high enough to raise the arm on the icemaker it will not shut off. Most people lift the arm up when they see the bucket full. I have the side by side Whirlpool model and on mine if I don't raise the arm the ice will fall out the bucket before it will raise the arm high enough.

Look for an ice cube lodged in the fingers IM. Get a hair dryer and melt that dude. No ice cube? Add some water to the IM mold. If it kicks out some ice but makes no more then you is gonna need a water valve. If it don't kick out no ice then you is gonna need a ice mold thermostat. Either one is very easy and cheap to fix. let me know Kimosabe.

You've either got a bad timer on the ice maker or the water valve is defective. You need to verify that the timer is moving first. If it isn't try pushing in on the dial on the end of the ice maker. It is under the white square cover at the end of the ice maker, usually towards the door, but in some units it points to the left side wall. If it begins to run when you do that, then the timer is broken. If not then I would say that the valve is defective.
