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.

3. Test points T and H will verify the bimetal
thermostat is open or closed.
• Force motor run by shunting T to H.
• If motor doesn't run, motor is faulty. Replace ice
maker.
• If motor does run, bimetal thermostat is faulty.
Replace ice maker.
NOTE: Make sure freezer temperature is cold enough
to close the bimetal thermostat.
4. Leave jumper in for half a revolution, then touch
heater mold.
• If mold feels warm, heater works properly.
• If mold doesn't feel warm, heater is faulty.
Replace ice maker.
5. Remove jumper and water valve will energize in
last half of revolution, if mold heater has not
failed.
NOTE: Make sure freezer temperature is cold enough
to close the bimetal thermostat.
