ICE MACHINE DOES NOT CYCLE INTO HARVEST WHEN
WATER TOUCHES THE ICE THICKNESS PROBE
(NEW MODELS)
NOTE: The ice machine will make a thick or double slab
when a new freeze cycle is started with ice already present
on the evaporator.
Two of the most common scenarios are:
• The machines exceeds the 65 minute freeze time
and enters into an automatic harvest, but the ice
does not come off the plate.
• The ice damper/bin switch is opened/closed in the
harvest cycle before the ice releases.
If the ice thickness probe is suspected to be the
problem, use the following procedure.
Use a jumper wire between the (red) ice thickness
connector at the control box and any cabinet ground. If
after 5 seconds the machine goes into harvest, replace
the probe. If the machine continues in the freeze cycle,
the control board is causing the malfunction.
NOTE: If you suspect a defective probe, check
the wire harness between the ice thickness
probe & control board for continuity before
replacing.
