NM1250
MAINTENANCE: Auger
///////////////////////////WARNING////////////////////////////
Disconnect electrical power before
begining.
Handle auger with care, it has sharp edges.
/////////////////////////////////////////////////////////////////////////
In some installations the water supply to the
icemaker will be so concentrated with
dissolved minerals, (such as calcium
carbonate) that as ice is made, the
evaporator and auger become coated with the
minerals, requiring a more frequent cleaning
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
panel. 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 ice chute
cover to ice chute, and remove cover.
3. Unscrew and remove ice sweep.
4. Loosen band clamp under ice chute, and
remove ice chute from evaporator.
5. Remove 4 allen head screws holding
breaker to evaporator.
6. Pull up on breaker to remove auger.
Allow the auger to dry, the stainless steel of
the auger and evaporator must be clean and
bright. Clean the auger and evaporator as
required. DO NOT HONE THE
EVAPORATOR.
7. Replace the water seal.
8. Reverse to reassemble.
