Electrolux Refrigerator Error Code UI

The UI error code means the refrigerator's main control board has detected an incompatible or incorrect user interface board. The main board checks the identity of the user interface board when the refrigerator powers on, and this error appears when the two do not match. It most often occurs after a repair where the wrong replacement board was installed. The refrigerator may still run but will flag this error to alert the technician or owner to the mismatch.

A simple power reset will not permanently clear the UI error code. Because the error is caused by a hardware mismatch between the user interface board and the main control board, the error will return each time the refrigerator powers on until the underlying cause is corrected. The correct board must be installed or the wiring connection issues must be resolved before the code will clear and stay clear.

If the fix is simply replacing an incorrectly installed user interface board with the correct part, the board itself typically costs in the range of $50 to $200 depending on the model. If a technician is needed to diagnose and perform the replacement, labor costs will add to the total, generally bringing the full repair into the range of $150 to $400. If the main control board is also at fault, costs will be higher. Getting a firm diagnostic from a technician before purchasing parts is advisable.

If you or a previous technician recently replaced the user interface board, start by confirming that the installed board is the correct part for your exact model number. Check the rating plate on the refrigerator for the full model number and verify the board part number matches. If the board is confirmed correct, inspect the wiring harness connectors for any loose or corroded connections. If an incorrect board was installed, it will need to be replaced with the proper model-specific part.

The refrigerator may continue to cool while the UI error is active, but the display and control functions may be unreliable or non-functional since the user interface board is not operating as expected by the system. It is not recommended to leave the issue unresolved for an extended period, as the incompatible board could affect the ability to monitor temperatures or adjust settings. Address the board mismatch as soon as possible to ensure full and reliable operation.
