Product review (5 stars): Just what the repair needed. Perfect Replacement
My RF4289HARS smart fridge finally failed making ice. Watching YouTube it seemed like a 2 minute process to replace the ice maker.  The problem was either the ice maker assembly, water pump or circuit board. The latter being one I wasn't ready to attempt. Since the water pump worked fine pumping to the water dispenser, I made a gamble and guessed it was the ice maker.  After installing, about 3 hours later ice started dropping.

Don't pay a service company to diagnose and repair.  Perfect fit!
