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

Electrolux codesElectrolux oven codes

The controller failed to communicate with the (upper) 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 oven

The F23 error code on an Electrolux oven indicates a communication failure between the display board and the convection fan and oven lights control board. Specifically, this fault is detected on the data line between connector P2 on the display board and connector P2 on the convection fan and oven lights control board. These two boards communicate continuously during operation, and when the controller cannot establish or maintain that communication link, F23 is triggered and oven operation is interrupted.

The most likely cause of this fault is a wiring issue along the communication path between the two boards. Damaged insulation, loose connector pins, a corroded connector, or a broken wire in the harness running between P2 on the display board and P2 on the convection fan and oven lights control board can all disrupt the signal. Heat exposure inside the oven cavity can degrade wiring and connector integrity over time, making this a realistic failure point that should be inspected carefully before any board is replaced.

If the wiring and connectors check out and are found to be intact and properly seated, the fault points to a failed convection fan and oven lights control board. Replacing that board is the next step. If the error persists after replacing the convection fan and oven lights board, the display board itself is likely the source of the communication failure and should be replaced as the final step in the diagnostic sequence.

Common causes of F23

  1. 01

    Loose or disconnected wiring harness connector

    Wiring / connection

    The connector at P2 on either the display board or the convection fan and oven lights control board may have worked loose over time. Inspect both connectors for secure seating and signs of backing-out pins.

  2. 02

    Damaged wiring between P2 connectors

    Wiring / connection

    Heat exposure or physical wear can cause wires in the harness running between the two boards to break or short. Visually trace the harness and use a multimeter to check for continuity along each wire in the communication circuit.

  3. 03

    Corroded or burned connector pins

    Wiring / connection

    Connector pins at P2 on either board can corrode or sustain heat damage, increasing resistance in the communication line enough to cause a fault. Look for discoloration, pitting, or residue on the pins and connector housing.

  4. 04

    Failed convection fan and oven lights control board

    Part replacement

    If wiring is confirmed good, the convection fan and oven lights control board itself may have an internal failure preventing it from communicating. Replacing this board is the next diagnostic step after ruling out wiring issues.

  5. 05

    Failed display board

    Part replacement

    If replacing the convection fan and oven lights control board does not clear the F23 code, the display board is the likely culprit. A fault on the display board side can prevent it from initiating or maintaining communication over the P2 connection.

Frequently asked questions about F23

What does F23 mean on a Electrolux oven?
F23 means the oven's display board failed to communicate with the convection fan and oven lights control board. The fault is specifically tied to the connection between connector P2 on the display board and connector P2 on the convection fan and oven lights control board. This communication failure can be caused by damaged wiring, a loose connector, or a faulty board on either end of the circuit.
Can I fix the F23 error on my Electrolux oven myself?
A knowledgeable DIYer can start by inspecting and reseating the wiring connectors between the two boards, which requires no parts and may clear the fault. If the wiring is undamaged and connectors are secure, the repair moves on to board replacement, which involves working with internal oven electronics. If you are not comfortable working with appliance control boards and internal wiring, it is safer to call a qualified technician.
Is it safe to use my Electrolux oven with an F23 error code?
It is generally not recommended to continue using the oven while an F23 error is active. The fault affects the convection fan and oven lights control board, which means convection fan operation and oven lighting may not function correctly. Operating the oven without a functioning convection fan can result in uneven heat distribution and potential overheating in some configurations.
Will resetting my Electrolux oven clear the F23 code?
A reset by cutting power to the oven at the breaker for a few minutes may temporarily clear the F23 code, but if the underlying wiring or board fault remains, the error will return. A reset is useful for confirming whether the fault is persistent, but it does not repair damaged wiring or a failed control board. A proper diagnosis is needed to resolve the issue permanently.
How much does it cost to repair an Electrolux oven F23 error?
Repair costs vary depending on the root cause. If the fix is simply reseating a connector or repairing a wire, costs may be limited to a service call fee, typically in the range of $75 to $150. If the convection fan and oven lights control board needs replacement, parts and labor together can range from $200 to $400 or more. Replacing the display board, if required, can add a similar or higher cost depending on parts availability.
