3. Faulty refrigerant compressor or
controls. Power on light will be on.
4. High Temperature inlet air. Power on
light will be on
5. High ambient temperature. Power on
light will be on.
6. Clogged condenser fins. Power on light
will be on.
7. Shortage of refrigerant.

temperature
Determine the cause and make
corrections. Failure of compressor to run
may be due to several factors. A
qualified refrigeration specialist should
check all electrical and refrigerant
controls, or factory should be contacted if
unit is in warranty.
The dryer is designed for inlet air of
100°F. Temperatures above 100°F, may
cause poor performance and an
overloading of the condensing units.
Check the ventilation. Ambient
temperature should not exceed 110°F.
Air circulation around the dryer should be
adequate, and proper ventilation in the
equipment room should guarantee a
correct ambient temperature.
Clear fins of all obstructions. The
clogged fins in the condenser coil will
restrict air passage and reduce
refrigeration capacity, causing unit to
shut down due to overheating. Fins
should be periodically checked and
cleaned. Install ambient air filter.
Fix the leak and add a charge of
refrigerant. Loss of refrigerant will cause
improper functioning. A qualified
refrigerant specialist should perform the
necessary repairs, or factory should be
contacted if the unit is in warranty/
See solution in this troubleshooting guide
for the appropriate possible cause. "Hi-
Temp" Indicator Light is activated when a
sensor (thermal/current overload)
experiences excessive current draw to
the compressor or the temperature of the
compressor shell to which it is attached
becomes excessive. Energization of the
light indicates power to the compressor
has been disrupted for one of the above
reasons. This may be caused by
excessive ambient or inlet air
temperature but it is not directly
indicative of either condition.
