To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.

To access module and heater assembly,
remove three screws on front of module and
remove support assembly.
Module
To make ice, an ice maker needs power,
water, and sub-freezing temperatures.
Note: The freezer door switch turns off
power to the ice maker when the freezer
door is open. It will be necessary to manually
close the freezer door switch for some
troubleshooting steps. Ensure that the shut-
off arm is down and instruct customer on its
use if necessary.
To ensure power to the ice maker without a
meter, remove the module cover and take
note of the test points.
N - Neutral side of line voltage
M - Motor connection
H - Heater connection
T - Thermostat connection
L - L1 (hot)side of line voltage
V - Water valve connection
Place a 14 gauge jumper wire across test
points T and H. With hands clear of the
ice maker, manually close the freezer door
switch. This will put the ice maker in a
manual cycle. If the ejector does not rotate,
this indicates no power to the ice maker.
Trace power from the wall socket to the door
switch and to the connector. Repair circuit
and connections or replace door switch as
needed. If the ejector begins to rotate (very
slowly) there is power. With power present,
verify 0 VAC between test points
T and H (this verifies the thermostat
has closed). Verify heater resistance is
approximately 264 Ω. With motor running,
verify heater is heating. If no heat is
detected, replace mold assembly. Next
ensure water is supplied to the ice maker.
When the ejector blade gets to the 11:00
position, the water valve is energized for 7.5
seconds.
Verify the water valve has 120 VAC between
test points V and N and approximately 4.75
ounces of water is dispensed. If voltage is
present and water is not dispensed verify
water supply and fill rate. Poor water quality
can cause ice maker to fail or produce
unacceptable cubes. Install a water filter
