Refrigerator ice maker not making ice

An ice maker that's stopped producing cubes is often caused by a clogged water filter, a frozen or kinked supply line, or the ice maker arm being switched off. Checking the water supply and settings first avoids an unnecessary part replacement.

Symptoms

  • No new ice being produced over a day or more
  • Ice maker feels warm or doesn't cycle at all
  • Bin has old ice but nothing new is being added
  • Clicking sound from the ice maker but no water fills it

Likely causes

  • CommonIce maker turned off or arm in the up (off) positionMany ice makers have a simple on/off switch or arm that's easy to accidentally bump.
  • CommonClogged or overdue water filterRestricted water flow through an old filter can prevent enough water from reaching the ice maker.
  • CommonFrozen or kinked water supply lineThe thin tube feeding water to the ice maker can freeze, especially if the freezer runs very cold or airflow is blocked.
  • PossibleWater supply valve behind the fridge not fully openA partially closed shutoff valve restricts the water needed to make ice.
  • PossibleFailed ice maker moduleThe ice maker's internal motor or module can wear out after years of use.

What to do

  1. Check that the ice maker's on/off switch or arm is in the correct 'on' position.
  2. Replace the water filter if it's overdue, typically every 6 months.
  3. Confirm the water shutoff valve behind the fridge is fully open.
  4. Check for frost or a hard spot along the water line inside the freezer wall, which can indicate freezing; if found, unplug the fridge for a few hours to thaw it.
  5. Pour a small cup of water directly into the ice maker's fill area to test whether it will cycle and freeze on its own.
  6. Check the freezer temperature is cold enough (around 0F) for ice production to work properly.
  7. If water flow and settings are fine but no ice forms, the ice maker module itself may need replacement.

When to call a pro

If the water supply and settings check out but the ice maker still won't cycle or freeze water, an appliance technician can test or replace the ice maker module.
