- Before you test the ice maker - make sure you have sufficient water pressure, and that the fill tube to the ice maker is not frozen over like the above response says.

- If it is frozen over, I would suggest again checking the water pressure - but changing the water valve either way. This unit is about the age where the valve can start to drip, also causing it to freeze.

- If you DO NOT have a frozen fill tube, test cycle the ice maker to see if it will fill. If you aren't handy with a multimeter, you can just hold your hand on the water valve in the back as the ice maker is cycling. You should hear a humming sound and feel a vibration on the valve for 4-7 seconds towards the end of the cycle. If the ice maker completes the cycle without calling for water - change your ice maker.
