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.

and stripper.

Temperature Problems

Temperatures in freezer section that average more than

0 ± 2°F (18 ± 1°C) slow the formation of ice. Therefore,

complaints of inadequate ice production can sometimes

be corrected by setting the freezer thermostat to a

colder temperature. Thermostat cycling temperature in

the one-revolution ice maker is 17° ±3°F (-8° ±1°C).

Obviously, the ice will be well frozen when those

temperatures are achieved. But cycling time is slow if

freezer temperature is not cold enough to achieve

those temperatures easily.

Bimetal Thermostat

Follow "Test Procedures" (P. 37) to test operation of the

bimetal thermostat.

NOTE: Replacement thermostats are no longer

available for ice makers. If your thermostat is

faulty, order a new ice maker.

Thermal Fuse

A one-time thermal fuse, incorporated into the ice

maker wiring harness, protects the plastic liner from

melting if the ice maker overheats. The thermal fuse is

spliced into the red wire of the ice maker harness. It is

a nonresettable fuse, and it is designed to blow at

170°F (78° C).

Presence of this fuse in the circuit means that a "No

Ice" complaint could be caused by excessive heat.

Where overheating is the problem, replacement of the

wiring harness is a temporary solution. The ice maker

should also be replaced.
