What F018 means on a Electrolux range

The F018 error code on an Electrolux range indicates a failure in the oven relay board, sometimes referred to as the wiggler board. This component is responsible for controlling the relays that switch power to the oven's heating elements, including the bake and broil elements. When the control system detects that the relay board is not responding correctly or is producing unexpected signals, it triggers the F018 code and interrupts normal oven operation to prevent potential overheating or element damage.

Relay board failures can stem from several root causes. The relays themselves can wear out or become stuck in an open or closed position after repeated thermal cycling. Burnt or corroded relay contacts, failed solder joints on the board, or a completely failed relay driver circuit can all produce this fault. In some cases, a power surge or prolonged exposure to high heat inside the control cavity can degrade the board's components to the point of failure.

Because the F018 code points directly to the relay board as the faulty component, the primary diagnostic action is replacement of the oven relay board. There is limited value in attempting to test individual relays without specialized equipment, and the board is generally not serviceable at the component level in the field. Confirming correct voltage supply to the board before replacement is a reasonable preliminary check to rule out upstream power issues.

Common causes of F018

  1. 01

    Failed oven relay board

    Part replacement

    The relay board itself has failed internally, either due to worn relay contacts, failed solder joints, or a failed driver circuit. This is the most direct cause of F018 and replacement of the board is the primary corrective action.

  2. 02

    Relay stuck open or closed

    Part replacement

    Individual relays on the board can stick in an open or closed position after repeated thermal cycling, causing the control system to detect an abnormal state and trigger the fault code.

  3. 03

    Power surge damage

    Part replacement

    A voltage spike from a power surge can damage relay board components beyond recovery. If the error appeared shortly after a power event, surge damage to the board is likely.

  4. 04

    Heat damage to the relay board

    Part replacement

    Prolonged exposure to excessive heat inside the control cavity can degrade the relay board's components over time, leading to intermittent or permanent failure.

  5. 05

    Loose or corroded wiring connections to the relay board

    Wiring / connection

    Poor connections between the relay board and the main control harness can mimic a board failure. Inspect connector pins for corrosion or backing out before condemning the board.

Frequently asked questions about F018

What does F018 mean on a Electrolux range?
F018 indicates a failure in the oven relay board, also called the wiggler board. This board controls the relays that switch power to the oven heating elements. When the control system detects the relay board is not functioning correctly, it displays F018 and disables oven operation to prevent further damage.
Can I fix F018 on my Electrolux range myself?
If you are comfortable working with appliance electrical components and can safely disconnect power before beginning, replacing the oven relay board is a straightforward repair. The board is a direct swap and is not serviceable at the component level in the field. However, if you are unsure about working with high-voltage appliance wiring, hiring a qualified technician is the safer option.
Is it safe to use my Electrolux range when F018 is displayed?
You should not attempt to use the oven while F018 is active. The relay board controls power delivery to the heating elements, and a failure in this board means the oven cannot heat reliably or safely. Continuing to operate the range in this condition risks unpredictable heating behavior or no heating at all.
Will resetting my Electrolux range clear the F018 error code?
A reset by disconnecting power for a few minutes may temporarily clear the code, but it will return if the relay board has genuinely failed. Because F018 points to a hardware failure rather than a communication glitch, a reset is not a lasting fix. Replacing the relay board is required to resolve the fault permanently.
How much does it cost to fix F018 on an Electrolux range?
The cost to repair an F018 error typically includes the price of the replacement relay board plus labor if a technician is hired. Parts costs can vary depending on the specific model, and labor rates differ by region. In general, homeowners can expect to spend somewhere in the range of $150 to $400 or more for a professional repair, with DIY repair reducing the cost to parts only.
