Product review (5 stars): Supco replacement for Whilpool icemaker
Bought as a replacement for a 22 yr old unit in my Whirlpool refrigerator.  Installation was straight-forward although the included instructions were only marginally helpful.  I found it best if you have the old unit out and compare with the new one.  I did have to switch the shut-off bail to the new unit but this was minor.  The old unit was flaking off the coating on the ice tray and ended up as black specs in the cubes.  The product included several power connections to fit various units but I was able to use the existing hookup.
Overnight the ice bucket was nearly full and no black specs.
The unit has only been in service about a week so can't rate it's longevity.
Overall satisfied.
