Electrolux Oven Error Code F2

The F2 error code indicates a communication failure within the oven's electronic control system. Sub-code F21 means the main controller has lost communication with the auxiliary board, while F23 means it has lost communication with the glass touch panel. The fault can stem from a wiring problem or a failed board component.

It is not recommended to continue using the oven when an F2 error is active. A communication failure between control boards means the oven cannot reliably receive or process control signals, which could result in unpredictable behavior. The oven should remain out of service until the fault is diagnosed and repaired.

Repair costs vary depending on which component has failed. Wiring repairs or connector reseating can be low cost if done yourself. Auxiliary board or glass panel replacements typically range from around $80 to $250 or more for parts alone, depending on the model. Main controller replacements tend to be at the higher end of that range. Adding professional labor can bring total costs to between $150 and $400 or more.

A knowledgeable DIYer can begin by inspecting and reseating the wiring connectors at the controller, auxiliary board, and glass panel. If the wiring is intact and the sub-code is F21, replacing the auxiliary board is the next step. F23 points to the glass panel as the replacement item. If neither resolves the issue, the main controller may need to be replaced, which is a more involved repair.

A power reset by unplugging the oven or switching off the circuit breaker may temporarily clear the display, but the F2 error will return if the underlying communication fault is still present. A reset does not repair loose wiring or a failed board. A proper diagnosis and repair of the communication path is required for a lasting fix.
