AUGER MAINTENANCE
In some areas, the water supply to the ice maker will contain a high concentration of minerals, and that will result in an evaporator and auger becoming coated with these minerals, requiring a more frequent removal than twice per year. If in doubt about the condition of the evaporator and auger, the auger can be removed so the parts can be inspected.
Note: Water filters can filter out suspended solids, but not dissolved solids. “Soft” water may not be the complete answer. Check with a water treatment specialist regarding water treatment. For more information on removal of these parts, see REMOVAL AND REPLACEMENT.
1.To remove the auger, remove the front and top panels.
2.Push bail clamp back from the top of the chute cover.
