Use the following procedure and table to help
determine if a hot gas 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).
Important
Feeling the h o t gas valve outlet or across the h o t
gas valve itself will not work for this comparison.
The h o t gas valve outlet is on the suction side (cool
refrigerant). It may be cool enough to touch even if the
valve is leaking.
3. Feel the compressor discharge line.
n
Warning
The inlet of the hot gas valve and the compressor
discharge line could be hot enough to burn your hand.
Just touch them momentarily.
4. Compare the temperature of the inlet of the hot gas
valve to the temperature of the compressor
discharge line.
