Comments
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.
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.
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.
