MAINTENANCE: Auger
////////////////////////////WARNING/////////////////////////////
Disconnect electrical power before begining.
//////////////////////////////////////////////////////////////////////////
In some areas the water supply to the
icemaker will have a great deal of minerals in
it, and that will result in an evaporator and
auger becoming coated with these minerals,
requiring a more frequent removal than twice
per year. If in doubt about the condition of the
evaporator and auger, the auger can be
removed so the parts can be inspected.
Note. Water filters can filter out suspended
solids, but not dissolved solids. "Soft" water
may not be the complete answer. Check with
a water treatment specialist regarding water
treatment.
For more information on removal of these
parts, see REMOVAL AND REPLACEMENT.
1. To remove the auger, remove front and top
panels. If top panel cannot be removed, or if
there is less than 6" clearance over the top of
the machine, the gearmotor/evaporator may
be slid out for service access. See Removal
and Replacement.
2. Remove 3 hex studs holding the ice chute
cover to the ice chutebody, and remove the
cover.
3. Unscrew and remove ice sweep.
4. Loosen band clamp under ice chute, and
remove ice chute body from evaporator.
