Monitoring Harvest Light Correction
The harvest light stays off and
the ice machine remains in the
freeze sequence. The ice thickness probe is
causing the malfunction. Verify
that the ice thickness probe is
adjusted correctly.
The harvest light comes on,
and 6-10 seconds later, the ice
machine cycles from freeze to
harvest. The control board is causing
the malfunction.
