MAINTENANCE AND CLEANING: Auger
5. Clean the air cooled condenser:
/////////////////////////////WARNING//////////////////////////
Disconnect electrical power.
/////////////////////////////////////////////////////////////////////////
Use a vacuum cleaner or coil cleaner if
needed. Do NOT use a wire brush.
Disconnect electrical power, and remove the
filter. The filter may be cleaned or replaced.
Clean the condenser: the condenser may
appear to be clean on the surface, but it can
still be clogged internally. Check with a flash
light from the front to see if light can be seen
though the condenser fins.
In some areas, the water supply to the ice
maker will contain a high concentration of
minerals, 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.
/////////////////////////////WARNING//////////////////////////
Disconnect electrical power, shut off water,
and handle the auger with care, it has
sharp edges.
////////////////////////////////////////////////////////////////////////
1. To remove the auger, remove the front and
top panels.
2. Use drain hose to drain the evaporator.
3. Remove 3 hex studs holding ice chute
cover to ice chute, and remove cover.
4. Unscrew and remove ice sweep.
5. Loosen band clamp under ice chute, and
remove ice chute from evaporator.
6. Remove 4 allen screws holding breaker to
evaporator.
7. Pull up to remove auger.
After the auger has been removed, allow the
auger to dry: if the auger is not bright and
shiny, it must be cleaned.
Clean the auger and evaporator as required.
DO NOT HONE THE EVAPORATOR.
8. Replace the water seal.
9. Reverse to reassemble.
