EXAMPLES OF HOT GAS VALVE
INLET/COMPRESSOR DISCHARGE LINE
TEMPERATURE COMPARISON
Findings Comments
The inlet of the
hot gas valve is
cool enough to
touch and the
compressor
discharge line is
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.
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 hot gas 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.
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.
