Dear stockit2me,
First be sure the temperature in the freezer is stable at 12 degrees F or below
If its not the
thermostat in the
icemaker wont close and allow power to the valve.
Check all wiring and the plug to the icemaker.
Check the tube where the water comes in to see that its not frozen not allowing water to come into the
icemaker cup.
If you have an ohm meter, take the harness off the
inlet valve coil that supplies the water to the
icemaker. With the meter set at RX10 it should read between 200-500 ohms of resistance. If it doesnt read between those two it is defective.
The
thermostat in the
icemaker head can be tested for continuity. It should have continuity at its coldest. ( frozen )
