GE GFE28GYNFS Error Code CI

Error CI on GE : Ice maker fault — ice maker cannot communicate with the main board or has failed. Follow the troubleshooting steps below to diagnose and fix this refrigerator issue. ## What Error Code CI Means on a GE GFE28GYNFS Ice maker fault — ice maker cannot communicate with the main board or has failed to complete an ice-making cycle ## What This Error Means Error code CI on your GE refrigerator indicates a problem with the ice maker system. CI can appear when: the ice maker module cannot communicate with the main control board, the ice maker has failed to complete a harvest cycle within the allowed time, the water supply pressure is outside the acceptable range (20–120 psi), or the ice maker arm is stuck in the up (off) position. CI is one of the lower-severity GE refrigerator error codes — the refrigerator continues to cool normally and only the ice maker function is affected. In many cases CI is caused by the ice maker being turned off accidentally (arm knocked to the up position), by low water pressure, or by a frozen ice maker module that needs a reset. The most effective first step is to toggle the ice maker off and back on using the control panel, then wait 24 hours for the ice maker to complete its first cycle. If CI persists, check the water supply and test the water inlet valve. ## Quick Diagnostic Summary | Detail | Value | |--------|-------| | Error Code | CI | | Severity | Low | | Appliance | GE GFE28GYNFS GE Refrigerator | | User-Fixable | Yes | | Applicable Models | PFE28KYNFS, GFE28GYNFS, PYE22KYNFS | ## Step-by-Step Troubleshooting | Step | Action | What To Do | Expected Result | |------|--------|------------|-----------------| | 1 | Toggle ice maker off and on | Press the Ice Maker On/Off button on the control panel or use the GE SmartHQ app to toggle the ice maker off, wait 30 seconds, then turn it back on. Also ensure the ice maker arm (if your model has one) is in the down (on) position. | Ice maker is toggled off and back on. Arm is in the down position. Ice maker begins a new cycle attempt. | | 2 | Reset the refrigerator | Unplug the refrigerator from the wall outlet for 30 seconds, then restore power. This resets the ice maker communication module and main control board, often clearing CI when it was caused by a transient communication fault. | CI code clears from the display after power reset. Ice maker begins running normally within 24 hours. | | 3 | Check water supply pressure and line | Locate the water supply valve behind or below the refrigerator and verify it is fully open. Inspect the water supply line for kinks. To test pressure, disconnect the supply line from the refrigerator inlet and place it in a bucket — open the valve and measure how much water flows in 10 seconds. Adequate pressure (20-120 psi) fills approximately 13.5 oz (400 mL) in 10 seconds. | Water supply valve is fully open and the supply line is not kinked. Water flow rate confirms pressure is within 20–120 psi. | | 4 | Inspect water inlet valve | Unplug the refrigerator. Locate the water inlet valve at the rear lower section. Disconnect the wiring harness to the ice maker valve solenoid (usually one of two solenoids on the valve). Test the solenoid coil resistance with a multimeter — expect approximately 200–500 ohms. An OL reading means the solenoid has failed and the valve must be replaced. | Ice maker inlet valve solenoid reads 200–500 ohms (within spec). OL indicates a failed solenoid requiring valve replacement. | | 5 | Replace ice maker module if CI persists | If water supply is confirmed adequate and the inlet valve tests good, the ice maker module itself has likely failed. Order the replacement ice maker assembly for your GE model. Disconnect power, unplug the ice maker wiring harness, remove the old module (typically 2-3 screws), and install the new one. | New ice maker module installed. First ice harvest completes within 24 hours. CI does not return. | ## Frequently Asked Questions ### How long does a GE ice maker take to make ice after reset? After a CI code is cleared and the ice maker is reset, the first cycle typically takes 24 hours to produce the first batch of ice. The ice maker module cycles approximately every 90-180 minutes, producing 8-10 ice cubes per cycle. If no ice is produced after 24 hours, the issue has not been fully resolved. ### Does CI affect refrigerator cooling? No. CI only affects the ice maker function. The compressor, evaporator fan, and all cooling functions continue to operate normally. Your food remains safe during a CI fault. ### My ice maker arm is up — does that cause CI? Yes. On GE refrigerators with a mechanical arm ice maker, the arm in the up position signals the ice maker to stop producing ice. If the arm is accidentally knocked up (e.g., by an overfull ice bin), the ice maker stops and CI may appear. Simply push the arm down to resume ice production. ### What water pressure does a GE ice maker need? GE ice makers require a water supply pressure between 20 psi (minimum) and 120 psi (maximum). Below 20 psi, the water inlet valve cannot open properly and the fill cycle times out, triggering CI. Above 120 psi, overfilling may occur. The household average of 40-80 psi is ideal for GE ice makers. --- Last Updated: March 2026 · GE GE Refrigerator · Error Code CI ### Is it safe to keep using my GE with error CI? If error CI does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the refrigerator with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error CI on a GE ? Repair costs for error CI on the GE refrigerator depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a GE-authorized service provider for an accurate estimate based on your specific situation. ### What does error code CI mean on a GE refrigerator? Error code CI on GE refrigerator models indicates Ice maker fault — ice maker cannot communicate with the main board or has failed to complete an ice-. This error is detected by the appliance’s internal diagnostic system and displayed to alert the user that attention is needed.
