90 Part Number STH042 7/15
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.
