ICE MACHINE CYCLES INTO HARVEST BEFORE
WATER CONTACT WITH THE ICE THICKNESS
PROBE
Step 1. Disconnect the ice thickness probe from the
control board at terminal 1C.
Step 2. Bypass the freeze time lock-in feature by
moving the ICE/OFF/CLEAN switch to OFF and back
to ICE. Wait until the water starts to flow over the
evaporator, then monitor the Harvest light.
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.
