Problem Probable Cause Remedy
COMPRESSOR RUNS BUT
NO COOLING. TRIPPING
OVERLOAD.
(Compressor shell is hot to
touch).
Condenser fan not running.
Inadequate air flow through
the dispenser.
Blocked condenser fins.
Ambient air over 100°F 38°C.
Defective overload.
Defective compressor.
Check that the condenser fan is
running. If the fan is binding or
turning slowly, an overload condition
will occur.
Air flow is top front in, exhaust out
the rear. NEVER PLACE
ANYTHING ON TOP OF THE
DISPENSER. This will block the
airflow over heating the compressor
and causing it to trip the overload.
Remove the rear bonnet and check
the condenser fins. If unit is run in a
dusty environment, condenser fins
can become clogged, stopping the air
flow.
Brush out and clean with vacuum.
If the dispenser is working in an
environment over 100° ambient or is
drawing in discharged air, during a
heavy period, the unit may trip the
overload.
Overload works on shell temperature
and amperage draw and can be
defective. Replace as needed.
Refrigeration technician will verify if
the compressor is defective and needs
to be replaced.
