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.
