How to fix it

  1. Confirm the water supply is on and the water filter is not overdue.
  2. Check for a frozen fill tube; thaw if needed.
  3. If water reaches it but it still will not make ice, replace the ice maker assembly.

Why it happens

Typical signs: No or little ice · CI on the display

  • No or restricted water supply A closed saddle valve, kinked line, or clogged filter starves the ice maker.
  • Frozen fill tube The water fill tube to the ice maker is frozen.
  • Failed ice maker module The ice maker assembly itself has failed.

Replace your water filter

A clogged or overdue water filter is a common cause of low water and ice flow on GE refrigerators — they are meant to be changed about every 6 months. The OEM-style filter that fits most GE refrigerators is the XWF ($45-55 OEM, $18-28 compatible).
