How To Inspect the Ejector Gear
There are two types of ice makers, those in which all of the parts can be individually replaced and those in which some of the parts are clustered together into a control module. To determine which model you have remove the outer face plate. If there is knob, pull it off first, then pry off the face plate with a small screwdriver.
Caution: Please read our safety
information before attempting any testing or repairs.
Before inspecting the ejector gear, unplug the freezer to avoid an electrical shock hazard.
Modular units have holes in the module's face plate for test probes. If you see several holes, each marked with a letter, it is a modular unit. The gears are enclosed and cannot be inspected. If the module sounds as though it is operating or you you can see that the ejector blade moves but stops when it presses against the ice, then the gear may be worn and the control module must be replaced. Click on this link for instructions on replacing the control module.
Component units, like the one shown below, can be identified by their exposed gears and lack of holes for test probes.
There are two exposed gears which mesh together. If either of the gears are worn, then they may fail to turn the ejector cam which ultimately pushes the ice out from the ice mold. Inspect those gears for cracks, worn or missing teeth. If the tops of the teeth are rounded or you observe "shavings', the gears may need to be replaced.
