Why is my automatic icemaker not working?

The most common causes include the feeler arm being in the STOP (up) position, the water supply being turned off or not connected, or the freezer compartment being too warm. Ice cubes may also have fused to the side of the mold — move the feeler arm to STOP, remove the cubes, then return the arm to ON. Piled-up cubes in the storage bin can also cause the icemaker to shut off and should be leveled by hand. (Page 30)
