Hot Gas Valve Analysis
The valve can fail in two positions:
 Valve will not open in the harvest cycle.
 Valve remains open during the freeze cycle.
VALVE WILL NOT OPEN IN THE HARVEST CYCLE:
Although the coil is energized in the harvest cycle, the
evaporator temperature/pressure remains unchanged
from the freeze cycle.
VALVE REMAINS OPEN IN THE FREEZE CYCLE:
Symptoms of a hot gas valve remaining partially open
during the freeze cycle can be similar to symptoms of
an expansion valve, Capillary tube or compressor
problem. Symptoms are dependent on the amount of
leakage in the freeze cycle.
A small amount of leakage will cause increased freeze
times. As the amount of leakage increases, the length
of the freeze cycle increases.
Refer to the Parts Manual for proper valve application.
If replacement is necessary, use only “original”
Manitowoc replacement parts.
