Problem or Symptom Possible Cause Probable Correction
No ice No refrigeration, unit shut down and
refrigeration diagnostic light is on without
blinking 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.
No water to ice making section Water level sensor or harness not
working properly
Replace harness or sensor
Slow ice release during harvest Cubes are too large Check inlet water valve for leak through
Check float for sticking
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 sensing system by pouring about
10 ice cubes through the ice outlet port.
The bin full light should blink, indicating
that it has sensed the ice. If not, check
the sensors.
Check the ice sensors. Place an object
between the ice sensors, after 5 seconds
the Bin Full light will be glowing steadily,
if not check operation of sensors by
unplugging #4. Bin Full light will go on
after 5 seconds, If not, replace controller.
If the light does go on, replace ice
sensor set.
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 controller
Check low side pressure, if pressure
does not rise during harvest, and valve is
electrically OK, replace vapor inlet valve
