How to fix an ice maker not dumping ice?

Fixing an automatic residential refrigerator ice maker that freezes water successfully but fails to dump or harvest the ice cubes requires addressing mechanical jams, heater failures, or module defects. First, check if the ice cubes are fused together into a solid block inside the mold due to an intermittent temperature fluctuation. Second, test the harvest mechanism by triggering a manual test cycle using the front diagnostic button or jumper wire. Third, check for electrical continuity across the mold heating element. You can troubleshoot mechanical movement easily by observing the harvest rake. You can verify that your corrective action is successful when clearing jammed ice blocks, freeing stuck harvest prongs, or replacing a faulty ice maker module restores normal automated ice dumping cycles.
