Auger Inspection
The auger must be carefully inspected for wear
and scale. There are also wear areas like the
top bearing surface and the edges of the
flights. The edges of the auger have horizontal
serrations and highly machined areas in
between. If the auger has contacted the
evaporator wall, it will have very rough flight
edges and should be replaced.
Scale forms on the auger during normal ice
making. If scale is still on the auger after
cleaning in the ice machine, the scale can be
removed using ice machine cleaner and a
nylon scrub pad.
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.
Caution: 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 remove any sealant or debris
from the shoulder of the auger where the
water seal was.
