Remedy
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.
See the Start-up and Operation
Section of this manual. Be sure the
water bath is filled to fill line.
Check the agitator motor located on
the refrigeration deck. Be sure it is
plugged in and receiving power.
Check that the impeller is not
obstructed. Replace if needed.
Melt the ice bank and check the
location of the sensing bulb. Be sure
it is all the way down to the bottom
of the tube.
Check the ice bank control. Be sure
that the control has not overheated
and fused the contacts together.
Replace as required.
