Possible Correction
Check that ice machine and
condensing unit, if used, both have
power. If power light is out, check

indicator light. If there is power to
the motor, check motor windings
Check that liquid line valve shuts
off tightly
Check for damage to gear reducer
or auger bearings.
Ice is in the chute.
No ice in the chute. Check position
of sensors, check sensors for scale
build up
Check liquid line valve
Check condensing unit
