Checking Mold Heater Resistance
The mold heater resistance should measure
between 71 to 79 ohms. To check the mold
heater resistance through test points L and H:
1. Remove the ice bin and freezer shelf.
2. Detach the ice maker from the evaporator
plate. Do not to pull on the wire harness.
3. Rotate the ice maker so the module cover
faces toward the freezer door, then remove
the cover.
4. Lower the shut-off arm to the ON position.
Checking Water Valve Solenoid Coil
Resistance
The solenoid coil resistance should measure
between 295 and 360 ohms. It can be checked
at the water valve solenoid coil as shown in
Figure 9-13 or through the ice maker module
test points V and N as shown in Figure 9-14.
To check resistance through points V and N:
1. Remove the ice bin and freezer shelf.
2. Detach the ice maker from the evaporator
plate.
Do not pull on the wire harness.
3. Rotate the ice maker so the module cover
faces toward the freezer door, then remove
the cover.
4. Roll the ice maker so the shut-off arm side is
down with the module facing away from the
freezer.

5. Set the multimeter to ohmmeter function,
then insert one probe into point V and the
other into point N.
The multimeter test probe tips must be at least
1/2 inch long to contact the test points.
