We have the exact same model, and also the exact same circumstances. I tried heating the area with a hair dryer and the dispenser worked for a day or so and then locked up again. I've tried heating another time with no results. The ice auger spins freely, but no motor hum when you activate the ice lever. Trying to access the dispenser mechanism is frustrating. I can't find detailed diagrams.
