Will be On after the second auger motor trip, indicating that the
machine must be cleaned and/or inspected for drive train
maintenance and manually reset.
This button must be pushed if the auger motor has overloaded
twice.
On at all times when the master switch is ON and machine is
connected to electrical power.
On when ice level is low (unit making ice).
Normal 6 minute off/delay start. To prevent short cycling, the
machine will not restart after any shut off (excpet power to the

Too much current has been drawn thru the auger motor. This
light is ON for the 30 minutes that must pass before the machine
will automatically restart.
After the first Auger Motor Error, the next 60 minutes of operation
are monitored, and this light will be ON. If another Auger Motor
Error occurs, the machine shuts down.
