Findings Comments
The inlet of the hot gas 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 hot gas 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 hot gas
valve is hot and
approaches the
temperature of a hot
compressor discharge line.
Hot & Hot
This is an indication something is
wrong, as the hot gas 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 hot gas
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
hot gas valve leaking.
