Electrolux Air Conditioner Error Code F2

F2 on an Electrolux air conditioner indicates that the indoor evaporator tube temperature sensor has been detected as open or short circuited. This sensor sits on the evaporator coil and feeds temperature data to the mainboard. When the circuit fails, the unit cannot safely regulate cooling or heating cycles and will stop normal operation until the fault is resolved.

You should not continue running the unit with an active F2 error. Without a functioning evaporator tube sensor, the mainboard cannot accurately monitor coil temperatures, which can lead to coil icing, compressor overloading, or other secondary damage. Addressing the fault promptly will prevent more costly repairs.

A power reset may temporarily clear the F2 code if the fault was caused by a transient issue such as a momentarily loose connector, but the code will return if the underlying problem is not resolved. If the sensor has failed or wiring is damaged, the error will reappear as soon as the unit attempts to read the sensor during normal operation. A reset is useful for confirming whether the fault is intermittent, but it is not a repair.

A knowledgeable DIYer can start by checking that the sensor connector is fully seated at the mainboard and that the wiring is undamaged. If the connection looks good, testing the sensor resistance with a multimeter and comparing it to the resistance table for that sensor will confirm whether the sensor has failed. Replacing the tube sensor is a moderate-difficulty repair, but if the mainboard itself is suspected, professional diagnosis is recommended.

If only the wiring connection needs reseating or cleaning, the repair may cost little to nothing beyond a service call fee, which typically ranges from $60 to $120. Replacing the tube temperature sensor itself usually costs between $20 and $80 for the part, plus labor. If the mainboard requires replacement, total costs can range from $200 to $500 or more depending on the model and local labor rates.
