Service Fault Diagnosis
Operating status What to check Action
Gear Motor and
compressor run,
but
intermittently
1) Pressure switch (HPS) 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)
4) Is the refrigerant overcharged?
5) Is the refrigerant line and components
normal?
6) Is it a bad contactor?
7) Are the contactor connections loose?
1) Clean 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.
4) Vacuum and recharge the refrigerant.
5) Clean and replace the dryer.
6) Check the connections and replace if
defective.
7) Check and fix connections.
Gear Motor
works,
but the
compressor
does not run
or runs
intermittently.
1) Compressor relay (PCB)
1) Is there a poor connection?
2) Is the PCB sending power to the
compressor?
1) Check the connections.
2) Replace PCB if defective.
2) Operation relay
1) Is there a poor connection?
2) Is the relay blown?
1) Check the connections and replace if
defective.
2) Replace.
3) Start/run capacitors, & OLP. 1) Bad parts? 1) Test and replace if necessary.
4) Compressor
1) Are the connections loose?
2) Is the winding shorted or fused?
3) Is the overload prevention open?
1) Check and connect correctly.
2) Replace compressor.
3) Check for high temperature or over current.
Ensure the OLP is not open. Cool
compressor if necessary.
5) Power Supply 1) Is the circuit current ampacity low? 1) Replace with correct breaker size.
Gear Motor and
compressor
work,
but no ice is
produced.
1) Refrigerant line
2) Refrigerant restriction/bad part
3) Water supply
1) Is there a refrigerant leak?
2) Check for restrictions
3) Is water being supplied to the evaporator?
1) Check the refrigerant for leaks with a leak
detector, re-braise the leak and replace the
dryer, evacuate and charge with refrigerant.
2) Replace parts containing blockage or
restricting the flow of refrigerant.
3) Ensure the water reservoir is full.
