I purchased this home in Aug 2011, the first time I used the icmaker, it made ice but has not done so since. The water dispenser on the door works but not the icemaker.
First step: remove the white cover from the front of the ice maker assembly. It snaps on but you may have to use a screwdriver in the slots at the bottom of it to get it off. I would put a test meter set to ac voltage on the water valve connections behind the unit so when it cycles, you can tell if your getting the 120Vac to the valve.(If you keep the valve connected during this test you can avoid cycling the ice maker an additional time). Also for reference purposes, the ice maker valve is the one that the water line from the bottom of it goes up the back of the refrigerator. Now you need a piece of wire with insulation on it, stripped on both ends. Jump from “T” to “H” keeping in mind that this is 120Vac that your jumping the thermostat with in order to force a cycle,(don’t get shocked!). The cycle will take approximately 3 minutes at the end of which, the ice maker should fill. During this time, watch the test meter. You should see 120Vac reading to it for 7 to 9 seconds. If you don’t, the ice maker isn’t passing the voltage and the ice maker motor module requires replacement. If you do see the voltage, the water valve is in need of replacement.
Jumping “N” to “V” should cause the water valve to open, filling the ice mold. Here is a link on how to use a multi-meter.

Also be aware this is a generic description of what to do. Specific instructions are by model number.
