Service Fault Diagnosis
Operating status What to check Action
Low ice yield
1) Refrigerant
1) Is there a refrigerant leak?
2) Is the refrigerant line blocked?
3) Is the refrigerant under/overcharged?
1) Check for leaks with a leak detector, repair the
leak and replace the dryer, evacuate and
charge with refrigerant.
2) Replace any clogged parts.
3) Recover, evacuate, and recharge with refrigerant.
2) High-side pressure
is too high
1) Is the condenser and/or filter dirty?
2) Is the ambient or water temperature too high?
3) Is the condenser fan not spinning, slow, or have a broken
fan blade? (Air-cooled)
1) Clean the air filter and/or condenser.
2) Place machine in cooler environment and check
the water supply.
3) Replace the fan motor or fan blade after
determining which is the issue.
3) Expansion valve
(TXV)
1) Is the low-side pressure too low or too high?
1) Replace if stuck open or closed.
2) Check that the bulb on the expansion valve is
properly installed and replace it if necessary.
Operating status What to check Action
Abnormal noise
1) Fan motor 1) Are the bearings worn?
2) Is the fan blade deformed or broken?
3) Is fan blade hitting the shroud?
1) Replace motor.
2) Replace fan blade.
3) Check alignment and/or replace fan blade.
2) Compressor 1) Is the bearing worn or the cylinder valve broken?
2) Is the rubber bushing assembled correctly?
1) Replace compressor.
2) Readjust the bushing assembly position.
3) Refrigeration Line 1) Is it caused by contact with refrigerant line components? 3) Realign or replace if necessary.
4) Gear Box 1) Are the bearings or gears worn and damaged? 1) Replace gear box.
5) Evaporator 1) Are the auger bearings worn out?
2) Is there a scale inside the evaporator cylinder?
1) Check & replace if necessary.
2) Disassemble the auger and related parts, descale and
clean with descaling agent. (Periodically)
Water overflow
from the
sump(Overflow)
1) Water supply 1) Is the water supply pressure too high (above 80psi)? 1) Install a water pressure reducing valve.
2) Water supply valve 1) Does the water inlet solenoid valve close? 1) Clean or replace the valve.
3) Water level sensor 1) Is connection bad or is the sensor reading properly? 1) Check the connections and replace if defective.
Gear Motor
'MOTOR ERROR'
flashes frequently
1) Power supply 1) Is the voltage too high or too low? 1) Connect the power to the rated voltage.
2) Ice making unit 1) Are the bearings (E-Head and Housing) or Auger worn? 1) Replace bearing or auger.
3) Tachometer 1) Is motor rotation bad? 1) Check the capacitor. 2) Replace the gear motor.
1) Check the capacitor. 2) Replace the gear motor.
4) Gear Motor or Gearbox 1) Is the motor or gearbox rotation bad?
