Electrolux Dryer Error Code F 02

Control temperature sensor open or shorted.

Electrolux codesElectrolux dryer codes

Control temperature sensor open or shorted.

First step from the service manual

Remove the wires from the control temperature sensor and measure the resistance of the sensor. If the meter does not read 50,000 Ohms +/- 10% replace the sensor. If the meter reading is within 10% of 50,000 Ohms, check the wiring between the electronic control board and the sensor. If the wiring is good, replace the electronic control board.

What F 02 means on a Electrolux dryer

The F 02 error code on an Electrolux dryer indicates a fault with the control temperature sensor, specifically that the sensor circuit has been detected as either open (broken circuit) or shorted (circuit resistance has collapsed). The control temperature sensor is a thermistor, a resistive component whose resistance changes predictably with temperature. At normal ambient conditions, this sensor should measure approximately 50,000 ohms. When the electronic control board reads a resistance value that falls outside an acceptable range, either because the circuit is open or the sensor has shorted to a very low resistance, it triggers the F 02 fault and typically halts the drying cycle to prevent potential overheating or damage.

The diagnostic process centers on isolating whether the fault is in the sensor itself or in the wiring and control board. With the wires disconnected from the sensor, a reading of 50,000 ohms plus or minus 10% (meaning between approximately 45,000 and 55,000 ohms) indicates the sensor is functioning correctly. A reading outside this range points directly to a failed sensor. If the sensor reads within spec, the wiring harness between the sensor and the electronic control board must be inspected for damaged insulation, corroded terminals, or broken conductors. If both the sensor and wiring check out, the electronic control board itself is the likely source of the fault, as it may be misreading or failing to process the sensor signal correctly.

Common causes of F 02

  1. 01

    Failed control temperature sensor

    Part replacement

    The thermistor itself has failed, producing a resistance reading outside the 50,000 ohm plus or minus 10% specification. This is the most common cause and is confirmed by disconnecting the sensor and measuring its resistance directly with a multimeter.

  2. 02

    Open or broken sensor circuit

    Wiring / connection

    A break in the wire between the sensor and the control board causes the circuit to read as open, with no continuity. Inspect the harness for visible damage, pinched wires, or broken connectors along the entire run to the control board.

  3. 03

    Corroded or loose wiring connections

    Wiring / connection

    Corrosion or a poor connection at the sensor terminals or control board connector can introduce excessive resistance or interrupt the signal. Disconnecting and reseating connectors while inspecting for oxidation can identify this cause.

  4. 04

    Shorted sensor wiring

    Wiring / connection

    The sensor wiring can short against the dryer cabinet or another wire, causing a collapsed resistance reading at the control board. Look for insulation wear at points where the harness contacts metal edges or heat sources.

  5. 05

    Faulty electronic control board

    Part replacement

    If the sensor measures within specification and all wiring checks out, the electronic control board may be failing to correctly read or process the sensor signal. Replacing the control board is the final step in the diagnostic sequence.

Frequently asked questions about F 02

What does F 02 mean on a Electrolux dryer?
F 02 indicates that the electronic control board has detected a fault with the control temperature sensor circuit. The sensor is either open, meaning the circuit is broken, or shorted, meaning the resistance has dropped outside the acceptable range. The dryer stops operation when this code appears to prevent potential damage from uncontrolled temperatures. Diagnosis starts by measuring the sensor resistance directly, which should be 50,000 ohms plus or minus 10%.
Can I fix F 02 on my Electrolux dryer myself?
Yes, a knowledgeable DIYer can diagnose and often repair this fault. You will need a multimeter to measure the sensor resistance after disconnecting its wires. If the reading is outside 45,000 to 55,000 ohms, replacing the sensor is the fix. If the sensor reads correctly, inspect the wiring harness for damage before considering a control board replacement.
Is it safe to run my Electrolux dryer when F 02 is displayed?
Running the dryer while F 02 is active is not recommended. The control temperature sensor is part of the dryer's thermal management system, and operating without a reliable temperature reading could result in overheating. The dryer typically stops the cycle automatically when this code appears, and that protective behavior should be respected until the fault is resolved.
Will resetting my Electrolux dryer clear the F 02 code?
A power reset may temporarily clear the code, but if the underlying fault with the sensor or wiring persists, the F 02 error will return. Resetting is not a repair. The sensor resistance and wiring need to be tested and the root cause corrected to permanently resolve the fault.
How much does it cost to repair an Electrolux dryer F 02 error?
Repair costs depend on the faulty component. A replacement control temperature sensor is generally an affordable part, typically in the range of $15 to $50. If the electronic control board requires replacement, parts alone can range from $100 to $250 or more. Adding professional labor can bring total repair costs to $150 to $400 depending on the component replaced and local service rates.
