Resumen del manual


6. Open coil on gearmotor start relay causing an immediate torque error. 1. Check that unit is plugged in, circuit breakers are on. 2. Adjust or replace ice level control. 3. Check reservoir for water, restore water to unit. 4. See Problem #6. 5. Repair or replace gear motor. 6. Replace gearmotor start relay. 2. Compressor will not run. System status: gearmotor and fan motor run. 1. Condenser coil plugged causing open overload or high pressure cut-out. 2. Defective starting capacitor. 3. Defective starting relay. 4. Open motor winding. 5. No power output from compressor output terminal on control board. 1. Clean condenser coil and replace overload if necessary. 2. Replace start capacitor. 3. Replace relay. 4. Check winding resistance and replace compressor if necessary. 5. Check terminal connection and replace control board if necessary. 3. Unit cycles 1. Float reservoir running dry, sensing probe 1. Check water supply to float and float intermittently. signalling for system to shut down. operation. PC board will have flashing WTR LED. System status: compressor, gear motor, and fan motor cycle. 4. Low ice production. Poor quality ice. 1. Dirty condenser coil. 2. Restricted air flow to condenser coil. 3. Mineral coated evaporator. 4. High ambient water supply and/or air 1. Clean condenser. 2. Remove obstruction. 3. Clean evaporator. 4. Precool water and/or install air duct temperature. 5. Improper exhaust air provisions. 6. Faulty expansion valve. 7. Low refrigerant charge. 8. Superheat incorrect. 9. Inefficient compressor. per Follett installation manual. 5. Provide proper exhaust air provisions per Follett installation manual. 6. Replace expansion valve. 7. Check for leaks; repair, evacuate, and weigh in correct charge. 8. Check that TEV sensing bulb is securely clamped in place and not damaged; check that insulated bulb cover is in place. Replace TEV if necessary. 9. Replace compressor. 5. Water leaks 1. O ring seal broken. 1. Replace O ring. from bottom of evaporator. 29 Troubleshooting Problem Indicators/possible cause Corrective action 6. Icemaker runs for short period of time and shuts down on torque error. System status: 20M or 2nd LED are lit. 1. Kink in ice transport tube. 2. Bin level control remains in closed position. 3. Ice transport tube ruptured internally. 4. Worn evaporator bearings. 5. Faulty gearmotor start relay. Icemaker torques out within 5 seconds of start-up. 6. Torque-out occurs when storage bin fills to capacity. 1. Eliminate kink and check that tube routing complies with Follett icemaker installation manual. 2. Adjust or replace control. 3. Replace complete run of ice transport tube. 4. Inspect bearings for roughness or binding and replace if necessary. 5. Replace gearmotor start relay. 6. Ensure that ice contacts bin thermostat before backing ice up in transport tube. Reference dispenser manual for proper thermostat and ice tube mounting. 7. Evaporator is iced 1. Gearmotor running but no output rotation. 1. Check for broken gearmotor output up on the outside. 2. Float reservoir empty. shaft or damaged gearbox. No ice production. 3.
