Product review (5 stars): New unit fixed both existing issues
The ice maker in our 20+ year old Whirlpool side by side refrigerator (ED20PKXAW01) had been having issues for a few months.
The ice cubes (crescents) were sticking together in the bucket and forming a huge clump of ice. I'd tried reducing the ice cube size via the wheel on the side - to no avail.
Occasionally there would be flakes of paint at the corners of some of the ice cubes.
After some internet research I'd managed to temporarily resolve the ice agglomeration issue by placing a cup in the ice bucket to catch dripping water from the ice molds at the far end of the ice maker.  However, in order to maintain the supply of ice I found that I needed to remove and replace the cup a couple of times a day.
My research indicated that the paint flakes were coming from the non-stick coating on the molds.
I knew I needed to replace the maker itself due to the paint issue, I wasn't sure of the root cause of the water dripping: was it the ice-maker or the solenoid valve in the supply line?
After reading some of the Amazon reviews I decided to go with the Whirlpool complete kit rather than some of the off brands due to poor reviews relating to flaking of non stick paint on brand new units.
I got free shipping and the box arrived 2 days after ordering on a Saturday (I don't have Prime)
I removed the old maker: 3 screws and a 4 pin wiring harness and installed the new unit.  So far it is working fine: no leaks and no paint contamination. At this point I haven't replaced the solenoid valve but it's there if I need it.
Upon examination of the old unit I discovered that the non-stick paint was flaking off the molds at the webs between the ice cubes revealing a very porous aluminium cast surface. After 20 years of cooling and heating cycles, I'm not surprised that the paint was beginning to flake off.
After reading the installation instructions that came with the new kit I discovered that there is a leveling screw that I was unaware of - the ice maker was installed in the fridge when I bought it.  I suspect that after 20+ years of use the ice-maker had been pushed out of alignment which was causing the leaks at the far end of the unit. If I'd known about the leveling screw I may have been able to resolve one issue.
Replacing the entire unit fixed both issues and left me with a spare solenoid valve - just in case.
Hopefully this maker will last as long as the original.
I probably should replace the filter now - I can't remember when I last did that. . ..
