GE Refrigerator Error Code CI — Ice Maker Error
What this means
The CI error code on GE refrigerators indicates a problem with the ice maker. This could mean the ice maker is not receiving water, the harvest cycle is not completing, the water supply is blocked, or the ice maker module itself has failed. Common causes include a frozen fill tube, a closed water supply valve, low water pressure, or a faulty water inlet valve.
Step-by-step fix
4 stepsVerify the ice maker is turned on
Check that the ice maker's power switch or arm is in the ON position. On GE refrigerators, this is typically a toggle switch or a wire arm on the side of the ice maker. If the arm is raised or the switch is off, no ice will be produced.
Items in the freezer can accidentally bump the ice maker arm to the off position.
Check the water supply valve
Locate the water supply valve behind the refrigerator or under the kitchen sink. Make sure it is fully open. A partially closed valve reduces water pressure below what the ice maker needs to fill.
The ice maker requires at least 20 PSI of water pressure to function properly. A trickle of water at the dispenser indicates low pressure.
Inspect the fill tube for ice blockage
The fill tube is a small tube that delivers water to the ice maker mold. If it is frozen solid, no water can reach the ice maker. Use a hair dryer on low heat to thaw the tube. Work carefully to avoid melting any plastic components.
A frozen fill tube is very common and often caused by a freezer temperature set too low or a faulty fill tube heater.
Reset the ice maker
Many GE ice makers have a reset button or test switch. Press and hold the reset button for about 10 seconds. The ice maker will run through a test harvest cycle. If water fills and the ice is ejected, the ice maker is working. If not, the module may be faulty.
After resetting, allow 24 hours for the ice maker to produce a full batch. It takes time for the first cycle to complete.
When to call a professional
If the water supply is good, the fill tube is clear, and the ice maker still does not produce ice after a reset, the ice maker assembly or the water inlet valve may need replacement. A technician can test both components.
