Ice Maker

Specifications

Mold heater: 185 watts, 264 ohms

Thermostat:	Close 17 ± 3°F (-8 ± 1°C)
(bimetal)	Opens 32° ± 3°F (0°± 1°C)
Water fill:	140 cc, 7.5 sec.
Motor cycle:	Stamped in circuit.
	Plug in connectors.
	One revolution of blades takes
	3 minutes plug stall time on ice
	(eject and water fill).

Operation

Thermostat closes when temperature reaches 17° ± 3°F (-8.3° ± 1.5°C). Current flows through thermostat to motor. See “Ice Maker Wiring Diagram”. Motor is linked with drive gear. From module, there are copper contacts that ride on copper strips on backside of drive gear. As the drive gear rotates, contacts will make or break a circuit (tract) to the copper strips to operate ice maker.

All components can be tested without removing ice maker or moving refrigerator away from installation. Remove cover.

Test points are identified on module:

N = Neutral side of line

M = Motor connection

H = Heater Connection

T = Thermostat connection

L = L1 side of line

V = Water valve connection

Testing Procedures

Verify ice maker has power, shut-off arm is down, and freezer is cold enough to close bimetal thermostat.

•Test point L and N will verify 120 volts to ice maker module.

•Test points T and H will verify bimetal thermostat is open or closed.

•Verify test probes go into test points 1/2 inch (1.25 cm).

1.Short T and H with a shunt (insulated 14 gauge wire with ends stripped back 5/8 inch (1.6 cm)) to run motor. If motor runs, replace bimetal thermostat. If motor does not run, replace module.

2.Leave jumper in for half of revolution. Touch heater mold. If heater mold feels warm, heater is working properly.

3.Remove jumper. Water valve will be energized in last half of revolution if mold heater has not failed.

Caution

To avoid ice maker damage do not short any contacts together other than those specified.
