Whirlpool Ice Maker Fix or Replace?

I have a whirlpool as well and had similar problems of my ice maker not working and I spent days making sure the supply line was working, the drain wasn't clogged, replaced the inlet valve, and none of it worked.

I ended up buying a new complete Ice Maker Assembly and swapped out old for new and started working right away. I should've just bought the $80 dollar assembly from the get go and not tried to diagnose little components.
I just ordered one online for $80. Pulled the old one out already. Noticed the coating on the freezing tray is flaking off. Was going to let it set out overnight and see if it will function if I put it back in.
 
I've had to replace two ice makers on Whirlpools in the last 10 years. It's seemingly always the control board, and costs several hundred dollars.

Meanwhile, the original fridge (from 1994) got demoted to basement duty, and it's sitting there while we're on the second replacement of it since 2013,
 
I opened the lid to find ice cubes sitting on top of the fingers that rotate and remove the cubes from the tray so they can fall into the hopper.

In addition to the other suggestions, check that the bail arm is functioning correctly and in the down position (iow, bin is not full of ice). If not, the new ice cubes will never eject, and new water will never fill the freezing tray. Check anything else that might tell the ice maker to halt its cycle: door switches, thermostats, bin sensors, etc.

Also, make sure the ice isn't jammed into the freezing tray, which would prevent the ejection fingers from ejecting the cubes.

We had a similar problem with the ice maker in our freezer. I don't remember the fix, but it turned out to be simple. I think the bail arm was not going down far enough due to ice buildup or a lodged cube.

No bail arm cubes drop down into hopper. Sensor in the door controls when ice maker stops due to full hopper. Sensor functions as it should.
 
My wife bought one of those standalone pellet ice makers a few years ago and that ****** sounds like an airplane going off at this point. I want to get rid of it but heaven forbid she have to have non-pellet ice.
 
Update! Ice maker arrived on Saturday I installed on Sunday. Took an hour for the first set of cubes to be made but it worked. Well sort of. It only filled 4 of the five cubes.

I had read that the water filter could case it not to fill all the cubes. I really didn’t want to start messing with the little plastic water adjustment screw, so I ordered a replacement filter. Well the early Monday delivery from Amazon didn’t happen due to weather, but arrived around 8 last night. Replaced the filter this morning and boom all cells are full!! I had not replaced the filter in about 2 years. Filter and ice maker ran $130. So I really don’t know what the issue with the old one was probably the board, just glad it’s working!
