Problem Possible Cause Possible Solution
Ice Blade is frozen in-place
1. Motor Overload setting is too high. 1. Adjust the Motor Overload setting at the Control Module (CM).
2. Ice is freezing too thick or too hard. 2. Adjust both valve controllers to factory settings. (see pgs. 31-32)
3. Drive Motor has stopped. 3. See “Drive Motor will not start” above.
4. Flex Coupling is broken. 4. Check and replace Flex Coupling as necessary.
Ice Flaker not meeting rated
capacity
Run Field Capacity Check before making any adjustments (see p.15).
1. Incorrect Evaporator Temperature. 1. Adjust Temperature Control to factory settings. (see pgs. 31-32)
2. Supply water temperature is outside
mandatory range.
2. Adjust supply water to between 45°F and 90°F. For temperatures below range,
contact Howe about Low Temperature Mixing Valve.
3. Ambient temperature is outside mandatory
range.
3. Adjust ambient temperature to between 50°F and 100°F. In unable to adjust,
relocate the Ice Flaker. For temperatures below range, contact Howe about Low
Ambient Kit.
Ice freezes together
in the Ice Bin
1. Water Distribution Pan is overflowing. 1. Adjust Water Regulating Valve so the Water Distribution Pan is halfway full.
2. Water from Side Spouts or Lead Spout is
not reaching freezing surface of
Evaporator.
2. Clean spouts of any debris or blockages. Make sure all spouts are perpendicular to
and within reasonable distance from surface of Evaporator.
3. Water is “ramping” off rings of ice formed
on Evaporator.
3. Adjust Kelvin II controller to factory settings. (see pgs. 31-32)
4. Ice Bin is not draining properly. 4. Check that all drains are flowing freely and pitched away from Ice Bin.
5. Ice turnover is low and Ice Bin inventory
has become stale and clumped by lengthy
storage time.
5. Use or discard ice within a reasonable time of producing it. Contact Howe about
Energy Saver Ice Production Management System.
