Electrolux Refrigerator Error Code UF

The UF code (shown as ER UF) means the control board is not detecting the vent fan running properly. The vent fan is responsible for circulating air through the refrigerator, and when the control board cannot confirm the fan is operating as expected, it triggers this fault. The fan motor, its wiring, or the control board are the components involved.

Start by locating the vent fan, usually behind an interior panel near the evaporator coil. Check for ice blocking the fan blade and defrost the unit manually if present. If no ice blockage is found, test the fan motor for continuity and verify voltage is reaching it from the control board. A motor that has no continuity or does not spin with proper voltage applied needs to be replaced. If the motor is functional, inspect the wiring harness for damage or loose connections.

Yes, ice buildup around the evaporator or fan housing can physically block the vent fan blade and cause the UF code to appear. This can happen if the defrost system has failed or if the door has been left open repeatedly, allowing humid air to freeze around the fan. Manually defrosting the unit by unplugging it for 24 to 48 hours will clear the ice, but if the code returns, the underlying defrost system failure will need to be addressed.

Using the refrigerator with a UF code active is risky for food safety. The vent fan is critical for maintaining even temperatures throughout the compartments, and without it running properly, food may not stay at safe temperatures. You should check temperatures with a thermometer and transfer perishables if the refrigerator cannot hold below 40 degrees Fahrenheit while you diagnose the issue.

If the vent fan motor is the cause, the part typically costs between $30 and $80 depending on the specific model, and it is a moderate DIY repair requiring panel removal. Professional labor to diagnose and replace the fan motor generally adds $100 to $200. If the control board is the faulty component, board prices range from $100 to $300 or more, making professional diagnosis worth the cost before purchasing the part.
