After figuring out that neither the circulation fan for the ice-maker, nor the circulation fan for the freezer was working; I suspected that the main control board fan control had malfunctioned. I ordered both a new ice-maker and a control board. AppliancePartsPros.com got them to me within a couple of days with standard shipping, and their repair videos made it very easy to swap out both units. Everything is back up and running. Took less than an hour to fix!
