REMEDY
Check for "ON" position or no
continuity - replace switch.
Clean filter and fins or replace
condenser filter. (Filter not supplied
on some machines).
A) Check for 120V or 230V AC.
Replace fan motor or check fan
blades for obstructions.
B) Check compressor LED on circuit
board. If ON, relay coil should have
power (120 or 230 VAC).
Check compressor relay coil for 120
or 230vac.
NOTE: Always check power with
coil attached. If compressor LED is
ON and no 120 or 230vac - replace
board. If yes, 120 or 230vac - replace
relay.
Note: Relay contacts are normally
open.
Check compressor thermal
overload (N/C). If open check for
dirty condenser filter or adequate
ventilation and space around
machine.
Check refrigeration system for leaks
and proper charge.
(A) Set switch to ON position.
(B) Check switch and harness for
proper continuity.
Check all previous items that
pretain to refrigeration or cold water
recirculation
