Findings Comments
The inlet of the harvest
valve is cool enough to
touch and the
compressor discharge
line is hot.
Cool & Hot
Normal Operation
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
Leaking Harvest Valve
The harvest valve inlet did not
cool down during the freeze
cycle due to continual leakage
of compressor discharge gas
through the valve.
Both the inlet of the
harvest valve and the
compressor discharge
line are cool enough to
touch.
Cool & Cool
Harvest Valve Not Leaking
The compressor discharge line
should not be cool to the touch 5
minutes into the freeze cycle.
This symptom would not be
caused by a harvest valve
leaking.
