2. Extremely Thin at Evaporator Outlet
There is no ice, or a considerable lack of ice formation, at
the outlet of the evaporator.
Examples: No ice at all on the outlet half of the evaporator,
but ice forms on the inlet half of the evaporator. Or, the ice
at the outlet of the evaporator reaches 1/8 in. to initiate a
harvest, but the inlet of the evaporator already has 1/2 in.
to 1 in. of ice formation.
3. Extremely Thin at Evaporator Inlet
There is no ice, or a considerable lack of ice formation at
the inlet of the evaporator. Examples: The ice at the outlet
of the evaporator reaches 1/8 in. to initiate a harvest,
but there is no ice formation at all on the inlet of the
evaporator.
4. No Ice Formation
The ice machine operates for an extended period, but
there is no ice formation at all on the evaporator.
Evaporator Tubing Routing
Routing of the tubing on the back of the evaporator
determines the ice fill pattern failure mode. The
evaporator outlet tubing does not exit directly at the top
of the evaporator, but exits several inches below the top
of the evaporator. Extremely Thin at the Evaporator Outlet
will first be visible several inches below the top of the
evaporator. Extremely Thin at Evaporator Inlet will first be
visible at the bottom of the evaporator.
