GE ice maker shows E3 and will not harvest ice or stops mid-cycle.

Safety first: Disconnect power before removing the ice maker head or front cover. Moving parts can start unexpectedly.

• Access harvest assembly: Remove the front cover of the ice maker module (for modular GE units) or the internal panel covering the harvest motor and cam.
• Inspect the cam and motor: Look for broken plastic teeth, jammed ice, or mineral buildup on the harvest cam. Manually rotate the cam slightly (with power off) to see if it moves freely.
• Check the position switch: The harvest position switch is usually actuated by the cam. Ensure the switch lever is not bent or broken and that the switch clicks when pressed.
• Verify wiring: Confirm that the motor and switch connectors are firmly seated and wires are not pinched.
• Test operation: Restore power and initiate a harvest test (if your GE model has a test button or diagnostic mode). If the motor hums but does not turn, or E3 returns, replace the harvest motor assembly or the entire ice maker head.
