Electrolux Range Error Code F23

The controller failed to communicate with the convection fan and oven lights control board.

Electrolux codesElectrolux range codes

The controller failed to communicate with the convection fan and oven lights control board.

First step from the service manual

Verify wiring between P2 on the display board and P2 on the convection fan and oven lights control board. If wiring is good, replace convection fan and oven lights board. If the problem persists, replace the display board.

What F23 means on a Electrolux range

The F23 error code on an Electrolux range indicates a communication failure between the display board and the convection fan and oven lights control board. These two boards exchange data signals to coordinate the operation of the convection fan motor and the oven interior lighting. When the display board sends a signal and receives no valid response, or when the communication line is interrupted, it triggers the F23 fault. This type of inter-board communication typically relies on a dedicated wiring harness connecting specific connector ports on each board.

The primary connection to inspect is the wiring between connector P2 on the display board and connector P2 on the convection fan and oven lights control board. A break, loose pin, or corroded terminal at either connector can interrupt the data signal entirely. Heat cycling inside the range can cause connector housings to expand and contract over time, eventually loosening pin-to-socket contact. Inspecting the harness along its entire run for chafing, pinching, or heat damage is also important before concluding the wiring is intact.

If the wiring and connectors check out without visible defects and continuity is confirmed, the convection fan and oven lights control board itself is the most likely failed component, as it is the board being polled. If replacing that board does not clear the fault, the display board may have lost its ability to transmit or receive the communication signal properly and will need replacement.

Common causes of F23

  1. 01

    Loose or disconnected wiring at P2 connectors

    Wiring / connection

    The harness connecting P2 on the display board to P2 on the convection fan and oven lights control board may have a loose, unseated, or disconnected pin. This is the first point to check since it requires no parts and is a frequent cause of inter-board communication faults.

  2. 02

    Damaged or chafed wiring harness

    Part replacement

    The wiring between the two boards may be pinched, chafed, or heat-damaged somewhere along its run inside the range chassis. Inspect the full length of the harness for visible insulation damage or a broken conductor, which would interrupt the communication signal.

  3. 03

    Corrosion or oxidation on connector terminals

    Wiring / connection

    Terminal pins inside the P2 connectors on either board can develop corrosion over time from moisture or heat exposure, increasing resistance on the communication line enough to cause a fault. Check both connector housings for discolored or oxidized pins.

  4. 04

    Failed convection fan and oven lights control board

    Part replacement

    If wiring and connectors are confirmed good, the convection fan and oven lights control board itself may have an internal failure preventing it from responding to the display board. Replacing this board is the recommended next step after wiring inspection.

  5. 05

    Failed display board

    Part replacement

    If replacing the convection fan and oven lights control board does not resolve the fault, the display board may have lost the ability to properly transmit or interpret communication signals. This is the least common cause and should only be replaced after the other steps are exhausted.

Frequently asked questions about F23

What does F23 mean on a Electrolux range?
F23 means the display board has lost communication with the convection fan and oven lights control board. These two boards are connected by a wiring harness at the P2 connector on each board, and when that signal is interrupted, the range logs the F23 fault. The cause can be a loose wire connection, a damaged harness, or a failed circuit board on either end of the communication link.
Can I fix the F23 error myself, or do I need a technician?
A knowledgeable DIYer can attempt the first diagnostic step, which involves locating and inspecting the wiring harness between the P2 connectors on both boards. If the connectors are accessible and the wiring appears intact, reseating the connectors firmly may resolve the fault. If the problem requires replacing the convection fan and oven lights control board or the display board, those repairs are within reach for experienced DIYers but involve working with electrical components inside the range, so comfort with appliance disassembly is important.
Is it safe to use my Electrolux range while the F23 code is displayed?
An F23 fault means the display board cannot confirm the status of the convection fan and oven lights control board, so convection fan operation and oven lighting may not function correctly or reliably. Basic bake functions may still operate depending on the range model, but using a range with an active communication fault is not recommended until the fault is diagnosed and resolved.
Will resetting my Electrolux range clear the F23 error code?
Resetting the range by cycling the power at the breaker may temporarily clear the F23 fault display, but if the underlying cause is a hardware problem such as a loose connector, damaged wiring, or a failed board, the code will return once the range attempts communication again. A reset alone is not a fix and should only be used as part of the diagnostic process.
How much does it cost to repair an Electrolux range with an F23 error?
Repair costs depend on which component has failed. If the issue is simply reseating a loose harness connector, there is no parts cost involved. Replacing the convection fan and oven lights control board typically costs somewhere in the range of $80 to $200 for the part, while a display board replacement can range from $100 to $300 or more, with additional labor costs if a technician performs the repair.
