[. . . ] Check the bearing by: ·pushing the bail clamp back and removing the ice chute cover ·unscrewing the ice sweep ·unscrewing the breaker cover ·unscrewing the auger stud January 1997 Page 14 Single System RL CLEANING In some installations the water supply to the ice maker will be so concentrated with dissolved minerals, (such as calcium carbonate) that as ice is made, the evaporator and auger become coated with the minerals, requiring a more frequent cleaning 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. Switch off electrical power, and shut off the water supply. For more information on removal of these parts, see REMOVAL AND REPLACEMENT. To remove the auger, remove front and top panel. If top panel cannot be removed, or if there is less than 6" clearance over the top of the machine, the gearmotor/evaporator may be slid out for service access. Push bail clamp back and remove ice chute cover. Loosen band clamp under ice chute, and remove ice chute from evaporator. Remove 4 allen head screws holding breaker to evaporator. Allow the auger to dry, the stainless steel of the auger and evaporator must be clean and bright. Clean the auger and evaporator as required. Reverse to reassemble. DIVIDER, AUGER AND SLOTTED COLLAR ALLEN HEAD SCREWS January 1997 Page 15 Single System RL SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES A. Check: Voltage to the unit, restore it if there is none. Check: The master switch, switch ON if off. The machine will not run if there is not enough water in the reservoir. Restore/adjust water level. STATUS: NOTHING OPERATES D. Check: The gear motor, if it will not run, the liquid line valve will not open. If no power to it: Check: The indicator lights on the circuit board, the bin empty light should be ON, the no water light should be OFF . If the bin empty and no water lights are off, check the transformer. [. . . ] The two smaller gears and the oil should be in the lower case, the output gear will be with the cover. As you lower the cover onto the lower case, cover will have to be moved closer to the second gear after the output gear has cleared the second gear top bearing. E) After the case is together, and the locating pins are secure in both ends, replace all cap screws. Bench test the gearmotor, check for oil leaks, noise, and amp draw.
