Discharge Line Temperature Above 150°F (66°C) at
End of Freeze Cycle:
Ice machines that are operating normally will have
consistent maximum discharge line temperatures
above 150°F (66°C).
Verify the expansion valve sensing bulb is positioned
and secured correctly.
Discharge Line Temperature Below 150°F (66°C) at
End of Freeze Cycle
Ice machines that have a flooding expansion valve will
have a maximum discharge line temperature that
decreases each cycle.
Verify the expansion valve sensing bulb is 100%
insulated and sealed airtight. Condenser air contacting
an incorrectly insulated sensing bulb will cause
overfeeding of the expansion valve.
