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 hot gas valve.
3. Feel the compressor discharge line.
4. Compare the temperature of the inlet of the hot gas
valves to the temperature of the compressor
discharge line.
Important
Feeling the hot gas valve outlet or across the hot
gas valve itself will not work for this comparison. The
hot gas valve outlet is on the suction side (cool
refrigerant). It may be cool enough to touch even if
the valve is leaking.
!
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.
