Understanding the Problem
If your refrigerator stopped producing ice or is producing small, hollow, or misshapen cubes, the ice maker assembly itself is often the culprit. The ice maker contains a motorized ejector, fill switch/thermostat, and electrical contacts; any of these can fail and stop the cycle even when the water supply is fine. In many cases the entire ice maker module is replaced because repair of internal gears or thermostats is not practical. Before replacing the unit, check for simple serviceable causes: ensure the water supply is on, the inlet valve is functioning, and the freezer temperature is cold enough (around 0°F / -18°C). If those items check out and the ice maker never cycles, cycles intermittently, or produces malformed cubes, replacing the ice maker assembly is typically the correct repair and the quickest way to restore reliable ice production.
Common Symptoms
No ice production, ice maker won’t cycle, partial or small hollow cubes, ice stuck in the mold, or the ejector arm won’t move.
Common Causes
- Failed ice maker motor/gear assembly or broken drive train inside the module
- Faulty fill switch/thermostat or electronic control inside the ice maker preventing the cycle
- Water inlet valve or water supply issues leading to no fill (sometimes diagnosed as an ice maker problem)

Helpful Repair Tip
Confirm the ice maker is faulty by manually advancing the ice maker into a harvest cycle (use the test/jumper pins or consult your model's service procedure) — if it won't cycle or the ejector motor doesn't run while power is present, the ice maker assembly usually needs replacing.
Frequently Asked Questions
Can I replace the ice maker myself?
Yes — many homeowners can replace an ice maker with basic tools (screwdriver, socket set). Always unplug the refrigerator or shut off power, shut off the water supply, and consult your model's service manual. Replacement typically requires removing the ice bin, disconnecting a wiring harness and mounting screws, swapping the module, reconnecting, and testing the cycle.
How much does replacing an ice maker cost?
Part costs usually range from $50 to $200 depending on brand and whether you buy OEM or aftermarket. If you hire a technician, add labor — expect $100–$250 total in many areas. Always verify part compatibility with your refrigerator model number before purchase.
