REMOVAL AND REPLACEMENT: Auger
To Remove the Auger:
Turn off the water to the machine, and unclip
the evaporator drain hose, pull it down and
drain the evaporator into the bin or a container.
1. The top panel must be removed, or, if that
is not possible, the gearmotor and freezer
assembly must be pulled part of the way out
from the cabinet. To do that:
a. Unclip the electrical wires from the hanger
near the drive motor.
b. Remove the bolt holding the gearmotor
plate.
c. Pull the assembly out.
2. The auger and breaker/bearing may now be
removed as an assembly.
a. Unscrew 4 allen head cap screws holding
breaker to evaporator.
b. Lift up on breaker and remove auger from

evaporator.

BREAKER
ASSEMBLY
Note: If the auger is stuck, the breaker
must be removed from the auger.
The breaker may be removed from the auger
and evaporator without disturbing the auger.
a. Use spanner wrench and unscrew
stainless breaker cover from breaker (left
hand threads)
b. Unscrew auger stud from top of auger.
c. Unscrew 4 allen head cap screws holding
breaker to evaporator.
d. Use a slide hammer type puller to pull on
the auger at the threaded hole. The size of
that hole is 5/8"-18.
Inspect the auger, the critical areas of the
auger are:
a. The auger body. It should be clean and
shining. Sometimes an auger will appear
clean when wet, but after it is dry it will be
seen to be stained. Scrub the auger with ice
machine cleaner and hot water.
///////////////////////////WARNING//////////////////////////////
Ice machine cleaner is an acid. Handle it with
extreme care, keep out of the reach of
children.

b. The water seal area. Because the auger
has been removed, the water seal will have to
be replaced. Remove the water seal top half
from the auger, and inspect the auger for
minerals clean as required.
