What Does Monogram Freezer Error Code CI Mean?

The CI error code on a Monogram freezer indicates Check Ice Maker — the diagnostic system has detected that the ice maker is not operating within expected parameters, either failing to complete a harvest cycle or failing to fill with water properly.

Common Causes of the CI Error Code

  • Ice jam in the ice maker mold or ice bin – Fused or clumped ice blocks the ejector from completing a harvest cycle.
  • Frozen fill tube – The small tube delivering water to the ice maker can freeze solid.
  • Failed water inlet valve – The solenoid valve that supplies water to the ice maker has failed.
  • Ice maker module failure – The electronic module controlling fill, freeze, and harvest cycles has failed.
  • Freezer temperature too warm – If the freezer temperature is above 10°F (−12°C), ice cannot freeze within the cycle time.

How to Troubleshoot the CI Error Code

  1. Toggle the ice maker – Turn the ice maker switch off, wait 30 seconds, and turn it back on to force a cycle restart.
  2. Check for ice jams – Remove the ice bin and break up any clumped or fused ice.
  3. Thaw the fill tube – If the fill tube is frozen, carefully apply low heat with a hair dryer.
  4. Check freezer temperature – Verify the freezer is at 0°F (−18°C).
  5. Verify water supply – Ensure the water supply line is connected and the valve is open.
