WARNING
To avoid risk of electrical shock that can cause death or severe personal injury, disconnect unit from power before
servicing unless tests require power. Discharge capacitors through a 10,000-ohm resistor before handling. Wires
removed during disassembly must be replaced on correct terminals to ensure proper grounding and polarization.

Ice Maker Service Instructions
To minimize risk of personal injury and/or property
damage, read this section of the manual completely
before attempting any tests or adjustments.
!
CAUTION
Operation
When the thermostat senses temperature of 17 ±3°F
(-8 ±1°C), the thermostat closes. Current now has a
path through the thermostat to the motor.
The motor turns the drive gear. Electrical contacts
protruding from the module brush against copper strips
on the backside of the drive gear (illustration P. 41). As
the drive gear turns, the rotating copper strips make and/
or break connections between the electrical contacts,
controlling icemaker operations.
Design of the ice maker allows testing of all components
without removing the ice maker or having to access the
water valve.
Remove the cover and you will see test points identified
on the module as N, M, V, etc.
N: Neutral side of line
M: Motor connection
H: Heater connection
T: Thermostat connection
L: L1 side of line
V: Water valve connection

Test Procedures
Necessary preconditions: Ice maker plugged into
power; shut-off arm down; freezer not warmer than
2°F
1. Use voltmeter across test points L and N to verify
115 volts for ice maker module. Make sure test
probes go into test points at least 1/2" (1.3 cm).
2. Make a shunt: Get a 6" piece of 14-gauge wire.
Strip 1/2" of insulation off both ends and bend the
wire into a horseshoe shape (illustration P. 38).
