Resumen del manual
Before calling for service: • Check that there is ice in dispenser bin area • Check that all switches and circuit breakers are on • Check that congealed cubes are not causing a jam • Check that all drains are clear Symptom Possible causeSolution1. Does not dispense ice a. Faulty dispense gate b. Faulty dispense solenoid c. Power switch off or faulty d. Faulty dispense switch e. Wheel motor malfunction f. Drive chain off g. Sprocket key missing a. Replace dispense gate b. Replace dispense solenoid c. Check switch; turn on or replace if faulty d. Replace switch e. Check motor and replace as required f. Reinstall chain g. Install key and tighten sprocket 2. Does not dispense watera. Dispense switch faulty b. Faulty water solenoid c. Solenoid plugged by debris a. Check switch and replace if faulty b. Check solenoid and replace if faulty c. Remove and clean valve 3. Water runs continuouslya. Dispense switch contacts burned shut b. Debris preventing valve from closing a. Check switch and replace if faulty b. Remove and clean valve 4. Dispense wheel rotates continuouslya. Dispense switch contacts burned shut b. Faulty level fill timer c. Faulty level fill relay a. Replace dispense switch b. Replace level fill timer c. Replace level fill relay 5. Icemaker runs a. Faulty or incorrectly positioned bin a. Check for proper positioning (middle of continuouslythermostat b. Incorrect field wiringadjustment range); if thermostat does not open when ice is placed on capillary tube, replace thermostat b. Check that icemaker receives bin signal from dispenser 6. Ice dispenses by itself a. Faulty dispense gate b. Faulty dispense solenoid c. Faulty dispense switch a. Replace dispense gate b. Replace dispense solenoid c. Replace dispense switch 16 Troubleshooting SensorSAFE board and sensors Board guide LEDs, when illuminated, indicate the following: Terminals: PWR (board power) L1 (incoming power, hot) CLN (cleaning, no dispensing cycle) L2 (neutral terminals) ICE (ice dispensing activated) WTR (power terminal for water solenoid) WTR (water dispensing activated) SOL (power terminal for dispense gate solenoid) not used WM (power terminal for wheel motor) CLN (terminals for clean cycle switch) Problem: Does not dispense ice or water Action PWR LED StatusCLN ICE/WTRSolution Check LEDs on control board OFF OFF OFFCheck circuit breakers and power switch; restore power or replace defective switch ON ON OFFDepress clean switch located under left side of front cover to return board to normal operation Place cup under drop zone ON OFF OFFTroubleshoot appropriate lens/sensor and replace if required (see Lens/Sensor Troubleshooting below) ON OFF ON Verify power on appropriate output terminal (WTR SOL or WM) on control board and replace board if required; if board tests okay, troubleshoot appropriate dispenser component Problem: Dispenses ice or water continuously Action PWR LED StatusCLN ICE/WTRSolution Check LEDs on control board ON OFF ONTroubleshoot appropriate lens/sensor and replace if required (see Lens/sensor troubleshooting below) ON OFF OFF If there is power on any output terminal (WTR, SOL or WM) on control board, replace board Remove lens protective cover; adjust funnel so water doesn’t drip down lens or behind splash panel 17 Lens/sensor troubleshooting 1. Turn dispenser power switch off. 2. Remove splash panel. 3. Disconnect wires from output terminal(s) (WTR, SOL, WM) on board. 4. Gently remove appropriate sensor/mounting block assembly from panel by moving block sideways until edge of block clears retaining tab of panel. 5. Inspect lens and sensor assembly for foreign material and remove using non-abrasive cleaner. 6. Turn dispenser power on and test sensor by moving hands through activation area (no closer than1.9mm/3/16") in front of sensor. 7. If LED on board turns on and off, sensor is working properly and dispenser may be reassembled. If LED does not come on, switch sensor leads on board and retest. If the opposite LED comes on, board is defective and must be replaced. If LED does not come on, sensor is defective and must be replaced. Disassembly and replacement instructions Dispense chute removal 1. Remove dispenser front cover. 2. Slide plastic dispense chute cover up and out to remove. 3. Pull out four white plastic fasteners and remove dispense chute. Dispense wheel removal and installation Note: Models with top mount icemakers require removal of icemaker before removing wheel. 1. Remove all ice from storage area of dispenser. 2. Remove center thumbnut from dispense wheel. 3. Remove thumbnuts holding baffle inside bin and remove baffle, remove 1/4" bar. 4. Tilt rear of wheel up and lift off motor drive shaft. 5. After reinstalling wheel, secure baffle loosely with thumbnuts, but do not tighten. 6. Place a 1.6mm (1/16") spacer against wheel and allow baffle to drop until it touches spacer. dispenser front 7. Tighten thumbnuts and remove spacer. Drive bar removal 1. Remove dispense wheel from dispenser (see above). 2....
