Refrigerator completely stopped making ice even though water dispenser works normally and freezer temperature is correct.
Ice comes out of the tray in one large fused piece instead of individual cubes, or the ice bin freezes into a solid block after harvest.
Ice maker tray rotates past level or continuously spins without stopping, indicating a failed harvest motor or control module.
Ice forms in the mold but the assembly fails to eject cubes into the storage bin.
Ice maker produces undersized, partially frozen, or hollow cubes due to a faulty tray thermistor or defective harvest control.




💡 Pro Tip: How to Know If Your Ice Maker Assembly Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Refrigerator stopped making ice entirely even though the water dispenser still works
⚠️ Ice cubes freeze together into a solid block inside the ice bin after harvest
⚠️ The ice mold tray rotates past level or continuously spins without stopping
⚠️ Ice comes out of the tray in one fused piece instead of individual cubes
🔎 Diagnostic tip: Pull the tech sheet from behind the kick plate and run service diagnostic mode. If harvest test passes but you get a motor/switch error code (e.g., Code 23), and freezer temperature is verified at 0°F–5°F, the ice maker assembly itself is the most likely failure point. Confirm 120VAC is reaching the unit before replacing.
