DIAGNOSING ICE THICKNESS CONTROL CIRCUITRY
Ice Machine Does Not Cycle Into Harvest When Water Contacts The Ice Thickness Control Probe
Step 1 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.
Step 2 Clip the jumper wire leads to the ice thickness probe and any cabinet ground.
Step 2
Step 2 Jumper wire connected from probe to ground
Monitoring of Harvest Light
Correction
The harvest light comes on, and 6-10 seconds later,
ice machine cycles from freeze to harvest.
The ice thickness control circuitry is functioning
properly. Do not change any parts.
The harvest light comes on but the ice machine
stays in the freeze sequence.
The ice thickness control circuitry is functioning
properly. The ice machine is in a six-minute freeze
time lock-in. Verify step 1 of this procedure was
followed correctly.
The harvest light does not come on.
Proceed to Step 3, below.
Step 3 Disconnect the ice thickness probe from the control board at terminal 1C. Clip the jumper wire leads
to terminal 1C on the control board and any cabinet ground. Monitor the harvest light.
Step 3
Step 3 Jumper wire connected from control board terminal 1C to ground
Monitoring of Harvest Light
Correction
The harvest light comes on, and 6-10 seconds later,
ice machine cycles from freeze to harvest.
The ice thickness probe is causing the malfunction.
The harvest light comes on but the ice machine
stays in the freeze sequence.
The control circuitry is functioning properly. The ice
machine is in a six-minute freeze time lock-in (verify
step 1 of this procedure was followed correctly).
The harvest light does not come on.
The control board is causing the malfunction.
