Ice Markers Troubleshooting Guide

Water enters an ice maker through an inlet valve and flows into the ice maker mold.  The water is then frozen by the cold air in the freezer compartment.  When the temperature in the mold has dropped to around 10 or 15 degrees, a thermostat starts a motor and the mold heater. 

The heater melts the ice slightly from below the mold, and the motor slowly drives the ejector blades clockwise to push the ice from the mold into the bin below.  Next, the shutoff arm rises and the ejector blades return to their original position to start a new cycle.  When the bin is full, the shutoff armrests on the accumulated ice and stops the next cycle.
