Refrigerator Ice Maker Not Working — Causes and Fixes
An ice maker that stops producing is one of the most common fridge complaints, and most causes are simple. Work through these from easiest to hardest.
1. Check It Is Turned On and Not Jammed
Confirm the ice maker is switched on (a wire arm in the up position, or the unit toggled on). Remove the ice bin and clear any clumped or jammed ice that blocks the mechanism.
2. Check Freezer Temperature
Ice makers need the freezer at about 0°F to 5°F to cycle properly. If the freezer is warmer than ~10°F, the ice maker slows or stops. Make sure vents are not blocked and the freezer is actually cold.
3. Check the Water Supply and Filter
Confirm the water shutoff valve behind or under the fridge is fully open. A clogged or overdue water filter is a very common cause — replace the filter every 6 months. Low water flow means small or no ice.
4. Thaw a Frozen Fill Tube
The small fill tube that drips water into the ice mold can freeze shut, especially if the water pressure is low. Unplug the fridge and use a hair dryer on low to thaw the fill tube and inlet area. If it keeps refreezing, the water inlet valve or pressure may be the issue.
5. The Water Inlet Valve
If the supply is on, the filter is fresh, and the tube is clear but still no water reaches the mold, the water inlet valve (which needs adequate pressure to open) may have failed. It is a moderate DIY replacement.

FAQ
Most often an overdue water filter, a closed supply valve, a frozen fill tube, or the freezer running too warm. Check those in order before suspecting the inlet valve.
Every six months, or sooner if water/ice flow drops. An old clogged filter is a top cause of weak or no ice.
Always unplug an appliance and shut off its water supply before servicing. This guide is informational and not a substitute for a qualified technician.
