After looking on YouTube and ruling out possible causes like freezing, water outlet etc. I determined that the motor within the ice maker assembly had outlived its useful life. The video I watched on how to replace the ice maker assembly was done by AppliancePartsPros.com so I picked up the phone and ordered a new unit which arrived the next day. Simply followed the instructions and helpful hints from the video; from start to finish, maybe 10 minutes to replace...easy! Saved more than a couple of hundred bucks as well!
