Part Number STH042 7/15 85
Harvest 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 circuit board has initiated a harvest cycle,
the evaporator temperature remains unchanged from the
freeze cycle.
VALVE REMAINS OPEN IN THE FREEZE CYCLE:
Symptoms of a harvest valve remaining partially open
during the freeze cycle can be similar to symptoms of
an expansion valve, float valve 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 and an ice fill pattern that is “Thin at the Outlet”, but
fills in at the end of the cycle.
As the amount of leakage increases the length of the
freeze cycle increases and the amount of ice at the outlet
of the evaporator decreases.
Refer to the Parts Manual for proper valve application. If
replacement is necessary, use only “original” Manitowoc
replacement parts.
