Safety Limit Notes
• Because there are many possible external
problems, do not limit your diagnosis to only
the items listed in this chart.
• A continuous run of 100 harvests
automatically erases the safety limit code.
• The control board will store and indicate only
one safety limit – the last one exceeded
• If the toggle switch is moved to the off
position and then back to the ICE position
prior to reaching the 100-harvest point, the last
safety limit exceeded will be indicated.
• If the harvest light did not flash prior to the ice
machine restarting, then the ice machine did
not stop because it exceeded a safety limit.
Safety Limit Stand-By Mode:
The first time a safety limit shut down occurs, the
ice machine turns off for 60 minutes (Stand-by
Mode). The ice machine will then automatically
restart to see if the problem re-occurs. During the
Stand-By Mode the harvest light will be flashing.
If the same safety limit is reached a second time
(the problem has re-occurred) the ice machine will
initiate a safety limit shut down and remain off
until it is manually restarted. During a safety limit
shut down the harvest light will be flashing.
Re-start the ice machine using the following
procedure:
1. Move the ICE/OFF/CLEAN switch to OFF
and then back to ICE.
A. If the safety limit feature has stopped the
ice machine, it will restart after a short
delay. Proceed to step 2.
B. If the ice machine does not restart, see “Ice
machine does not operate” Section 5.
2. Allow the ice machine to run to determine if
the condition is reoccurring.
If the ice machine stops again, the condition has
reoccurred, and the cause must be determined.
If the ice machine continues to run, the condition
has corrected itself. Allow the ice machine to
continue running.
