When a safety limit condition is exceeded
(6 consecutive cycles for Safety Limit #1 or 500 cycles
for Safety Limit #2) the ice machine stops and the
harvest light on the control board continually flashes
on and off. Use the following procedures to determine
which safety limit has stopped the machine.
1. Move the toggle switch to OFF.
2. Move the toggle switch back to ICE.
3. Watch the harvest light. It will flash one or two
times, corresponding to safety limit 1 or 2 to
indicate which safety limit stopped the ice machine.
After safety limit indication, the ice machine will restart
and run until a safety limit is exceeded again.
