Ambients Air Temperature1 Minimum Maximum Fahrenheit 50 F 100 F Celsius 10 C 38 C Water Temperature2 Minimum Maximum Fahrenheit 40 F 90 F Celsius 4 C 32 C 1 - Ambient air temperature is measured at the air-cooled condenser coil inlet. 2 - Ambient water temperature is measured in the icemaker float reservoir. 25CI400A/W • 25HI400A • 50CI400A/W • 50HI400A Dispenser troubleshooting Before calling for service 1. Check for ice in the ice storage area. 2. Check that congealed ice is not causing a jam. 3. Check that all switches and circuit breakers are on. 4. Check that all drains are clear. Lever model troubleshooting guide WARNING • Disconnect power to unit before putting hands or arms in storage area or attempting any repair or service to equipment Problem Indicators Corrective Action Does not dispense ice. 1. Power switch off or faulty. 2. Faulty dispense switch. 3. Wheel motor malfunction. 1. Check switch – turn on or replace if faulty. 2. Replace switch. 3. Check motor and capacitor and replace Dispense wheel rotates continuously. Dispense switch contacts are burned out. Replace dispense switch. Icemaker runs continuously. Faulty or incorrectly positioned bin stat. Check for proper positioning. If stat does not open when ice is placed on capillary tube, replace stat. Does not dispense water. 1. Faulty water solenoid valve. 2. Faulty dispense switch. 3. Power switch off or faulty. 1. Replace water solenoid valve. 2. Replace dispense switch. 3. Check switch - turn on or replace if faulty. SensorSAFE model troubleshooting guide Problem Action SensorSAFE Board LED Status Corrective Action PWR CLN ICE/WTR Does not dispense ice and/or water. Check LEDs on the SensorSAFE control board. OFF OFF OFF Check circuit breakers and power switch. Restore power or replace defective switch. ON ON OFF Press clean switch on lower left side of electrical enclosure to return board to normal operation. Place cup under drop zone (in front of lens) ON OFF OFF Troubleshoot appropriate lens/sensor and replace if required (see lens/sensor troubleshooting). ON OFF ON Verify power on appropriate output terminal (WTR or WM) on control board and replace board if required. If board tests okay, troubleshoot appropriate dispenser component. Dispenses ice and/or water continuously. Check LEDs on control board. ON OFF ON Troubleshoot appropriate lens/sensor and replace if required (see lens/sensor troubleshooting). ON OFF OFF If there is power on any output terminal 9WTR or WM) on control board, replace board. Board guide LEDs, when illuminated, indicate the following: PWR (board power), CLN (cleaning, no dispensing cycle), ICE (ice dispensing activated), WTR (water dispensing activated). Terminals: LI (incoming power, hot), L2 (neutral terminals), WTR (power terminal for water solenoid), WM (power terminal for wheelmotor), CLN (terminals for clean cycle switch). Lens/sensor troubleshooting 1. Turn dispenser power switch off and remove splash panel. 2. Disconnect wires from WTR and WM terminals on board. 3. Gently remove sensor/mounting block from splash panel. 4. Inspect lens and sensor. Clean if necessary. 5. Restore dispenser power and test sensor by passing hand in front of sensor. 6. If LED on board turns on, sensor is operational. Re-assemble dispenser. 7. If LED does not come on, switch sensor leads on board and retest. 8. If opposite LED comes on, replace defective board. 9. If opposite LED does not come on, replace defective sensor. 25CI400A/W • 25HI400A • 50CI400A/W • 50HI400A Icemaker troubleshooting Flashing water LED at any time indicates that water signal to board had been lost for more than one second. Ten-second delay: There is a 10 second delay in reaction to loss of water (WTR) or bin (B-E) signals. If signals are not lost for more than 10 seconds, no reaction will occur. Problem Indicators Corrective Action Icemaker will not run. 1. No power to unit. 1. Check that unit is plugged in, circuit breakers are on. System status: compressor, 2. Open bin level control. 2. Adjust or replace ice level control. gearmotor, and fan motor inoperative. 3. Water OK LED (WTR) not on. 3. Check reservoir for water, restore water to unit. 4. 20M or 2ND LED is on indicating that first or second torque error has occurred. 4. See #6 below. 5. Gear motor locked up (immediate torque error indicated by LEDs when board is reset). 5. Repair or replace gearmotor. 6. Open coil on gearmotor start relay causing an immediate torque error. 6. Replace gearmotor start relay. Compressor will not run. 1. Condenser coil plugged causing open overload or high pressure cut-out. 1. Clean condenser coil and replace overload if necessary. System status: gearmotor and fan motor run. 2. Defective starting capacitor. 3. Defective starting relay. 4. Open motor winding. 5. No power output from compressor output terminal on control board. 2. Replace start capacitor. 3. Replace relay. 4. Ohm out windings and replace compressor if necessary. 5. Check terminal connection and re...
