Samsung RF28HFEDBSR/AA refrigerator No ice - no frosty chamber

[rddmar]

Everything on this 4 year old refrigerator works except suddenly the ice maker no longer makes ice. From what I've read it appears I'm joining the Samsung ice maker party!

The ice making chamber is completely free of frost, the freezer registers -2F the fresh food chamber registers 36F. Water pressure is fine, delivering nearly a pint in 10 seconds  at the cold water dispenser. I've tried resetting the unit by pressing in on the little blue button on the ice maker and gives a quick chime but nothing else occurs in the next 24 hours. I've tried resetting the machine by disconnecting it from 120V power for 5+ minutes and upon re-powering the freezer temperature shows -9F and 28F in the food compartment, No ice after 24 hours.

I'm looking for help in troubleshooting this refrigerator before I go on a simple parts purchasing chase. For what it's worth, my beer fridge is a 1947 GE that doesn't miss a beat.

Thanks for your help.
