Discharge Line Temperature Above 150°F (66°C) at End of
Freeze Cycle:
Ice machines that are operating normally will have
consistent 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 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.
