We have a Frigidaire 25.6 Cu. Ft. Side-by-Side Refrigerator, with an ice (cubed and crushed) and water dispenser on the freezer door. The ice maker has worked wonderfully since we bought this house in May, but lately it has stopped producing ice. The water dispenser still works perfectly. The ice maker makes the same sounds as if it is making ice but then nothing comes out into the ice box. On occasion, we find 2-3 new cubes in the ice box. We have consulted the manual and tried their suggestions, including checking the water connection lines and replacing the filter, and nothing seems to work. How can we fix this problem?
