Findings Comments
The inlet of the harvest valve
is cool enough to touch and
the compressor discharge line
is hot.
Cool & Hot
This is normal as the discharge
line should always be too hot
to touch and the harvest valve
inlet, although too hot to touch
during harvest, should be
cool enough to touch after 5
minutes into the freeze cycle.
The inlet of the harvest
valve is hot and approaches
the temperature of a hot
compressor discharge line.
Hot & Hot
This is an indication something
is wrong, as the harvest
valve inlet did not cool down
during the freeze cycle. If
the compressor dome is also
entirely hot, the problem is
not a harvest valve leaking, but
rather something causing the
compressor (and the entire ice
machine) to get hot.
Both the inlet of the harvest
valve and the compressor
discharge line are cool enough
to touch.
Cool & Cool
This is an indication something
is wrong, causing the
compressor discharge line to
be cool to the touch. This is
not caused by a harvest valve
leaking.
