Problem or Symptom Possible Cause Probable Correction
No ice No refrigeration, maximum harvest time
code is 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.
Slow ice release during harvest Cubes are too large Check ice thickness adjustment
Check for proper harvest of all ice
Condenser by-pass valve does not open Check coil of valve
Check power to valve during harvest
Ice is formed unevenly on
evaporator, thick at bottom
Excess water and heat load Check purge valve for leak through
Check water inlet valve for leak through
No ice harvested No ice released, vapor inlet valve does
not open
Check coil for continuity, if open replace
coil
Check for voltage to coil during harvest,
if non, check at controller
Check low side pressure, if pressure
does not rise during harvest, and valve is
electrically OK, replace vapor inlet valve
