What F-8 means on a Electrolux dryer

The F-8 error code on an Electrolux dryer indicates a surface element relay drive fault. This code is triggered under two distinct conditions: first, if any relay drive signal is detected as active for 16 consecutive seconds while all circuits are commanded off, suggesting a relay has failed in the closed position or a control board output is misfiring; second, if an open circuit is detected in the relay drive circuit at the moment power is first applied to the unit. Both scenarios point to a failure in the path between the control board's relay outputs and the relay coils or switching components that control heating elements.

The relay drive circuit is responsible for switching power to the heating element on and off under direction from the main control board. When a relay sticks closed, the element receives continuous power regardless of control commands, creating a potential overheating hazard. An open in the drive circuit means the control board cannot complete the signal path to activate or verify the relay, which also prevents normal operation. The control board monitors this circuit continuously and logs the fault when either condition is met at startup or during a cycle.

Diagnosing F-8 requires inspecting the relay drive circuit for both short circuits and open circuits. This includes checking wiring continuity between the control board relay outputs and the relay components, inspecting for burnt or corroded connectors, and testing the relays themselves for proper coil resistance and contact operation. In many cases the fault traces back to a failed relay on the control board itself, which may require board replacement if the relay is not serviceable separately.

Common causes of F-8

  1. 01

    Stuck or failed relay on the control board

    Part replacement

    A relay that has welded contacts will remain closed even when commanded off, triggering the 16-second active-drive fault. Inspect the relay for signs of burning or arcing and test contact continuity with power removed.

  2. 02

    Open circuit in the relay drive wiring

    Wiring / connection

    A broken wire, loose connector, or corroded terminal between the control board and the relay can create an open that is detected at power-up. Check all connectors and wiring in the relay drive circuit for continuity.

  3. 03

    Faulty main control board

    Part replacement

    If the relay drive output on the control board has failed internally, the board may send continuous or no signal regardless of operating conditions. This is suspected when wiring and relays test correctly but the fault persists.

  4. 04

    Burnt or damaged wiring harness connector

    Wiring / connection

    Heat and vibration over time can cause connectors near the relay drive circuit to melt, corrode, or pull apart, creating either a short or an open condition. Visually inspect all connectors in the circuit for discoloration or physical damage.

  5. 05

    Short circuit in the relay drive circuit

    Wiring / connection

    A pinched or chafed wire in the relay drive circuit can create an unintended current path that mimics a relay being held on. Trace the harness from the control board to the relay components and look for any wiring damage.

Frequently asked questions about F-8

What does F-8 mean on a Electrolux dryer?
The F-8 code indicates a surface element relay drive fault. It is triggered either when a relay drive signal is detected as active for 16 seconds while all circuits should be off, or when an open circuit is found in the relay drive path when power is first applied. The fault relates to the control circuit that switches the heating element on and off.
Can I fix the F-8 error myself on my Electrolux dryer?
Some causes of F-8 are DIY-accessible, such as inspecting and reseating wiring connectors or checking for visible wire damage. However, testing relay coil resistance and drive circuit continuity requires a multimeter and some electrical knowledge. If the fault points to a failed control board or internal relay, replacement is typically needed and many homeowners choose to have a technician handle that work.
Is it safe to use my Electrolux dryer when F-8 is displayed?
No, you should not continue using the dryer while F-8 is active. One of the conditions that triggers this code is a relay staying on when it should be off, which means the heating element could run continuously and create an overheating or fire risk. Discontinue use and diagnose the fault before operating the dryer again.
Will resetting the dryer clear the F-8 error code?
A power reset may temporarily clear the code, but if the underlying fault in the relay drive circuit still exists, the code will return at startup or during the next cycle. The F-8 condition is checked each time power is applied, so a reset alone is not a fix. The root cause in the wiring or relay components must be identified and corrected.
How much does it cost to repair an Electrolux dryer with an F-8 error?
Repair costs vary depending on the cause. If the fix involves cleaning or reseating a connector, the cost may be minimal beyond a service call fee, which typically ranges from $50 to $100. If a new control board is required, parts alone can range from $100 to $250 or more, with total repair costs including labor potentially reaching $200 to $400 depending on your location and the technician's rates.
