Answer to continue safely
Is it safe to keep using?
Yes. A CI fault affects only the ice maker. The refrigerator and freezer compartments continue to cool normally and food is safe. Simply use an alternative ice source until the ice maker is repaired.
Can I reset the code?
Yes. Power cycling the unit (unplug for 5 minutes) or pressing the ice maker test button can reset the CI code. If the underlying module or wiring fault is not addressed, the code will return.
When to stop immediately?
Stop if you notice: Water is leaking from the ice maker area — shut off the water supply valve immediately., The CI code is accompanied by other error codes suggesting broader control board failure..
Symptoms You May Notice
Ice maker stops producing ice
The ice maker completely stops cycling and ejecting ice cubes, even though water supply and freezer temperature are adequate.
CI code on display panel
The Monogram control panel shows CI, sometimes alternating with the set temperature.
Ice maker arm stuck or unresponsive
The ice maker's harvest arm or control arm does not move through its normal cycle when the ice maker is manually advanced.
No water fill to ice maker tray
The water inlet valve does not open to refill the ice maker mold after a harvest cycle, indicating the module is not sending the fill signal.
Possible Causes
Ice maker module failure
The ice maker's internal control module (the brain of the ice maker assembly) has failed and is no longer communicating with the main refrigerator control board.
Requires ProfessionalWiring harness disconnection
The wire harness connecting the ice maker to the main control board has come loose, been pinched, or damaged, interrupting communication.
DIY PossibleMain control board fault
The main refrigerator control board has lost the ability to communicate on the ice maker bus, requiring board replacement or reflash.
Requires ProfessionalIce maker arm in OFF position
The metal or plastic ice maker shutoff arm has been raised to the OFF position (or failed in the raised position), signaling the ice maker to stop production.
DIY PossibleSafe Checks You Can Do
-
1
Check the ice maker shutoff arm
Locate the wire shutoff arm on the side of the ice maker assembly. The arm should be in the down position for normal operation. Lower it manually if it is raised.
Some Monogram models use a sliding switch labeled ON/OFF rather than a wire arm — ensure it is set to ON.
-
2
Inspect and reseat the wiring harness
With the refrigerator unplugged, open the freezer and locate the wire harness connector running from the ice maker to the back wall. Disconnect and firmly reconnect it to ensure a good electrical connection.
Look for any signs of pinched, chafed, or melted wire insulation near the connector.

3
Reset ice maker module
Locate the test/reset button on the face of the ice maker module (small square button). Hold it for 3 seconds. The ice maker should begin a harvest cycle with an audible clicking sound.
If no test button is present, unplug the unit for 5 minutes to reset the module via power cycle.
When to Call a Professional
Contact a qualified technician if:
- The wiring harness is intact and the test reset does not restore ice maker operation — the ice maker module itself needs replacement.
- Multiple fault codes appear alongside CI, suggesting a main control board fault requiring professional diagnosis.
