Understanding the Problem
When an ice maker cycles but the ice tray never fills, the problem is almost always a water delivery issue — either the refrigerator isn't getting water to the ice maker, or the ice maker isn't signaling the valve to open. That can be caused by a failed water inlet valve (solenoid), a blocked or frozen fill tube, an obstructed water filter or supply line, or a faulty ice maker control/harvest mechanism. Diagnosing the fault requires simple checks: confirm the refrigerator has a cold water supply and the water dispenser (if present) works, inspect the fill tube and mold for ice blockage, and test the inlet valve and ice maker for electrical operation. Replacing the right part depends on which component fails those checks — commonly the water inlet valve, the ice maker assembly/module, or the water filter/supply line.
Common Symptoms
Ice maker cycles but mold stays dry; no water dispenses from ice maker; sometimes water dispenser works while ice maker doesn't; visible ice in fill tube (frozen) or droplets absent in fill cup.
Common Causes
- Failed water inlet valve (solenoid) — won't open to let water into the mold
- Frozen or blocked fill tube / clogged water line or filter
- Faulty ice maker control module, harvest switch, or fill sensor preventing valve activation

Helpful Repair Tip
To quickly confirm the inlet valve: turn the ice maker through one cycle and listen for the valve clicking when it should fill. If you have a multimeter, check the inlet valve coil for continuity; if the coil has continuity but no water flows and water pressure is OK, the valve is likely bad.
Frequently Asked Questions
Can I diagnose and fix this myself?
Yes — many causes are DIY-friendly. Start by confirming the water supply to the fridge is turned on, replace a clogged water filter, and inspect the fill tube for ice (thaw gently with a hairdryer on low, not open flame). If those don't help, listen for the inlet valve click during a fill cycle and test for continuity on the valve coils with a multimeter. If the valve doesn't energize or is defective, replace it. If you're not comfortable working with electrical components or shutting off the water, hire a qualified technician.
How much does it cost to replace the part that fixes this?
Costs vary by part and brand. Typical part-only costs: water inlet valve $30–$120, ice maker assembly $60–$250, replacement water filter $15–$60. Labor (if you hire a tech) can add $80–$200 depending on your area. Always confirm exact part number for your model before purchasing.
