Refrigerators

Water line to the ice maker or dispenser is frozen

A frozen water line inside the freezer wall stops both ice making and dispensing, and it's usually caused by the freezer running colder than necessary or reduced airflow around the line. Thawing it out and addressing the underlying cause prevents it from refreezing.

Symptoms

  • No water or ice comes out despite the supply being on elsewhere
  • Ice maker and dispenser both stop working around the same time
  • Problem developed gradually rather than suddenly
  • Freezer seems to be running colder than the recommended setting

Likely causes

  • CommonFreezer temperature set colder than necessaryAn overly cold freezer setting increases the risk of the thin water line freezing solid.
  • CommonWater line routed too close to a very cold spot or airflow ventCertain areas inside the freezer get colder than others, and a line running through one of these spots is more prone to freezing.
  • PossibleReduced water flow allowing the line to freeze more easilyA partially clogged filter reducing flow can make the standing water in the line more likely to freeze.
  • PossibleDoor left open frequently, causing temperature swings that promote ice formation on the lineFluctuating temperatures from frequent openings can contribute to ice forming around the line over time.

What to do

  1. Unplug the fridge and leave the freezer door open to let the area warm up and thaw naturally, which can take several hours.
  2. Speed up thawing carefully with a hair dryer on a low setting, keeping it a safe distance from plastic components and never using an open flame.
  3. Once thawed, check and adjust the freezer temperature setting to the manufacturer's recommended level, typically around 0F, rather than colder.
  4. Replace the water filter if it's overdue, since better flow can help prevent the line from sitting stagnant and freezing.
  5. Check that nothing is blocking normal air circulation right where the line runs, which might be making that specific spot colder than it should be.
  6. Plug the fridge back in and test both the ice maker and water dispenser after a few hours.
  7. If the line freezes again repeatedly despite a normal temperature setting, a technician can check for a routing or insulation issue with the water line.

When to call a pro

If the water line keeps freezing repeatedly despite a normal freezer temperature, a technician can check the line's routing and insulation for a design or damage issue.
