Diagnostics
SYMPTOMS
Bin Switch Fails Open
• The ice machine will not start an ice making cycle and
the display indicates “Full Bin”.
• The ice machine displays “Full Bin Remove Ice” in the
clean cycle.
Bin Switch Fails Closed
• When running a “Long Harvest” alert is displayed and
E02 Long Harvest indicated.
• May be off on a E02 Long Harvest.
• The harvest cycle continues after ice opens and closes
the ice damper (harvest cycle is 7 minutes).
Erratic Bin Switch Operation
• Abnormally short (less than 30 second) harvest times
in the data history screen.
• Occasional large slab of ice in bin due to bin switch
terminating harvest and starting another freeze cycle
before the ice released.
Ice Damper Binding/Sticking
• Low production (may be intermittent) with no alert
events.
• Owner notices the ice machine is off at a time when
it is normally running or the ice machine starts a new
freeze cycle when bumped.
NOTE: The ice damper may be dragging on the evaporator
extrusion. Rounding the inside edge on both ends of the
ice damper with sandpaper, a nail file or an emery board
will normally resolve this issue.
