SAFETY LIMIT INDICATION
Control Board with Black Microprocessor
When a safety limit condition causes the ice machine
to stop, the harvest light on the control board
continually flashes on and off. Use the following
procedures to determine which safety limit has
stopped the ice 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 limits 1 and 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.
