The valve solenoid fails to open, cutting off water supply to the ice maker mold — resulting in zero or very small ice cubes.
A faulty or clogged valve prevents water from reaching the dispenser even when house pressure and the water filter are both fine.
Corrosion or a worn valve diaphragm causes water to drip or spray from the supply line inlet area at the rear of the refrigerator.
Valve fails to close completely after the fill cycle, allowing continuous water seep that freezes the fill tube and overflows the ice mold.
Mineral deposits from hard water partially clog the valve's internal screen or diaphragm, severely reducing flow rate to the ice maker.
💡 Pro Tip: How to Tell If Your Water Inlet Valve Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Ice maker is not producing ice, or output has dropped to one small cube at a time
⚠️ Water dispenser produces no water despite adequate house water pressure and a clean filter
⚠️ Water leaking or dripping from the back of the refrigerator near the supply line inlet
⚠️ Ice maker overflows or fill tube freezes repeatedly — valve not closing fully
🛠 Diagnostic tip: With the fridge unplugged, check for visible corrosion or mineral buildup on the valve body. Then, with power restored, listen for a buzzing/humming sound when the ice maker calls for water — if you hear the solenoid activate but no water flows, the valve diaphragm has failed. Also inspect the fill tube for freezing, which is a secondary sign of a valve that won't close completely. Do NOT attempt to clean a clogged valve — replace it to prevent recurrence.
