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.
2. Remove bail clip and remove ice chute cover.
3. Unscrew ice sweep.
4. Remove ice chute body.
5. 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.
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. Unscrew 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. Lift up & remove breaker from evaporator.
e. If the auger is stuck 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:
1. 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.
Ice machine cleaner is an acid. Handle it with
extreme care, keep out of the reach of children.
2. 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.
