Part Number STH039 8/13 75
Discharge Line Temperature Above 66°C at End of
Freeze Cycle:
Ice machines that are operating normally will have
consistent maximum discharge line temperatures
above 66°C.
Verify the expansion valve sensing bulb is positioned
and secured correctly.
Discharge Line Temperature Below 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.
