and repair this product. Equipment damage, injury to personnel or death could result from im-
proper installation or unsafe action. Raritan Engineering Company, Inc. accepts no responsi-
bility or liability from damage to equipment, or injury or death to personnel that may result from

WARNING:
Refrigeration Equipment contains refrigerant fluids under very HIGH PRESSURE.
Danger of sudden pressure release resulting in injury, death, or severe frostbite may result from
not following instructions.
WARNING:
Hazard of Electrical Shock
TROUBLESHOOTING
Tools required:
Volt meter, 4" (10.2 cm) of insulated
#12 AWG (4.0 mm
2
) single conductor jumper wire.
WARNING - HAZARD OF ELECTRICAL
SHOCK: Tests requires AC power at module.
Proceed using EXTREME CARE.
NOTE: The shutoff arm must be in the DOWN
position.
MODULE NOT FUNCTIONING PROPERLY
Remove white plastic front cover of icemaker
module. Grasp cover firmly and pull.
1. System is inoperative; not cold.
The fan and compressor do not run when the unit
is on. Ejector “fingers” are not visable. Normal
position for ejector fingers is approximately 2:30
o’clock position. If fingers are in another position
and are not moving, the module drive mechanism
is stuck in the EJECTION CYCLE, the module
board may need replacing. Check for power by
placing probes of volt meter into test points L
and N with icemaker on, you should read a
nominal 120V AC (or 240V depending on the
units voltage). If no voltage is read on meter, the
problem may be with wire harness or other
electrical connection(s).
2. Fan and compressor run and ice bin is freezing
cold but there is no ice production.
If these conditions exist, perform the following
test:
Make a jumper out of a short piece of #12 AWG
(4.0 mm
2
) single conductor insulated wire. Bare
both ends by exposing a minimum of 1/2"
(1.3 cm) of uninsulated wire.
Insert the uninsulated ends of the jumper 1/2"
(1.3 cm) into terminal ports T & H (see Fig. A).
The compressor and fan should shut off and white
gear should start to rotate clockwise. If gear does
not rotate, module requires replacing. If gear
rotates for one complete cycle, module is ok and
mold thermostat (#I34T) should be replaced.
Remove jumper after 30 seconds.
