Part Number STH042 3/14 83
Use the following procedure and table to help
determine if a harvest valve is remaining partially open
during the freeze cycle.
1. Wait five minutes into the freeze cycle.
2. Feel the inlet of the harvest valve(s).
3. Feel the compressor discharge line.
4. Compare the temperature of the inlet of the
harvest valves to the temperature of the
compressor discharge line.
Feeling the harvest valve outlet or across the
harvest valve itself will not work for this
comparison.
The harvest valve outlet is on the suction side
(cool refrigerant). It may be cool enough to touch
even if the valve is leaking.
The inlet of the harvest valve and the compressor
discharge line could be hot enough to burn your
hand. Just touch them momentarily.
