The bin control uses devices that sense light, therefore they must be kept clean enough so that they can ``see''. At least twice a year, remove the bin control sensors from the base of the ice chute, and wipe the inside clean, as illustrated. The ice machine senses water level by a probe located in the water reservoir. At least twice a year, the probe should be removed from the reservoir, and the tip wiped clean of mineral build-up. PULL UP TO REMOVE PROBE CLEAN THE LIGHT SENSORS RESERVOIR See Removal and Replacement to replace bearing or seals. Check and tighten all bolts and screws. CLEAN THE WATER LEVEL PROBE ICE SWEEP /////////////////////////////////////////// CAUTION: THE TIP IS MADE OF GLASS ////////////////////////////////////////// 3. The bearing in the breaker should also be checked at least two times per year . BREAKER COVER January 1995 Page 17 NME950 & WRF540CWBM MAINTENANCE: Air Cooled Electrical shock hazard. Electrical shock can cause personal injury. Disconnect power before beginning to service components. 5. Clean the air cooled condenser. The air flow on this model is from front to back, so the inside of the machine will have to be available to clean the air cooled condenser. Use a vacuum cleaner or coil cleaner if needed. Check water supply, filter, strainer, float valve. Check/clean ice level sensors. Unit off due to ice level sensors (photo-electric eyes) blocked. Unit off due to scale on water level sensor. Unit off due to high pressure control open. Auger motor does not turn. Clean water level sensor. Check for water interruption (water cooled) or fan motor failure (air cooled). Check for a restricted system Check/replace centrifugal switch. Check, replace board Check, replace sensor Check/replace contactor Low pressure control open No ice, auger motor is turning Check start capacitor. Check start relay Check compressor windings Circuit board compressor relay Check, replace board will not close. High discharge pressure Clean the air filter and because of a dirty condenser condenser. Low capacity because the Clean the water system auger and evaporator are coated with mineral scale Low suction pressure due to Locate leak. [. . . ] When the proper charge is indicated on the scale, shut off the manifold valve(s). Shut off the valve on the refrigerant drum. Re-open the manifold valves until all liquid has flowed out of the hoses. Shut the low side access valve on the ice machine. [. . . ]
