Problem or Symptom Possible Cause Probable Correction
No ice No refrigeration, unit shut down,
maximum freeze time code displayed Check compressor, refrigerant charge,
and liquid inlet valve. Note that if liquid
inlet valve is not open, compressor will
pump down and suction pressure will be
very low.
Sump frozen Check power supply connection to CP.
Power supplied to wrong side of
contactor will cause compressor to run
all the time.
No water to ice making section Water level sensor working properly Clean or replace sensor
Slow ice release during harvest Cubes are too large Check ice thickness sensor
Check for water leak
Condenser by-pass valve does not open Check coil of valve
Check power to valve during harvest
No ice sensed during harvest Ice sensing system failure Check curtain switch
No ice released to bin Ice outlet blocked - check for obstruction
No ice released, vapor inlet valve does
not open Check coil for continuity, if open replace
coil
Check for 24 volts to coil during harvest,
if non, check at relay in EH222
Check low side pressure, if pressure
does not rise during harvest, and valve is
electrically OK, replace vapor inlet valve
