Electrolux Refrigerator Error Code F1

The F1 code on an Electrolux refrigerator means the control board has detected a fault with the refrigerator compartment air temperature sensor. This thermistor monitors the internal temperature of the fresh food section and sends resistance readings to the control board. When the signal falls outside the expected range due to a failed sensor, broken wiring, or a bad connection, the F1 code is triggered. The refrigerator may not cool correctly while this fault is active.

It is not recommended to rely on the refrigerator for food storage while F1 is active. Because the air temperature sensor is not functioning properly, the control board cannot accurately regulate cooling, which means the compartment may not maintain safe temperatures below 40 degrees Fahrenheit. Perishable food should be moved to another refrigerator or kept on ice until the fault is resolved.

A reset, such as unplugging the refrigerator for a few minutes, may temporarily clear the F1 code, but the error will return if the underlying sensor fault has not been corrected. Resets are useful for confirming whether a code is persistent or was triggered by a one-time power fluctuation. If F1 comes back after a reset, the thermistor, wiring, or control board needs to be inspected and tested before the fault is truly resolved.

A knowledgeable DIYer can address this error by first inspecting the wiring connector at the air sensor for looseness or corrosion, which requires no parts. If the connector looks intact, testing the thermistor with a multimeter and replacing it if out of range is a straightforward repair. However, if the control board is the root cause, that replacement is more involved and may be better suited for a qualified technician.

If only the refrigerator compartment air sensor needs replacement, parts typically range from $15 to $50, and a service call to have a technician install it would bring the total to roughly $100 to $200 depending on your area. If the fault is traced to the main control board, parts and labor can range from $200 to $400 or more. Checking the wiring and connector first costs nothing beyond your time and may resolve the issue without any parts.
