Electrolux Oven Error Code butn

The BUTN error code on an Electrolux oven indicates that one or more buttons on the user interface (UI) control panel is registering as permanently pressed or electrically shorted. The oven's control system continuously monitors the state of each button contact on the UI board. When a contact signal is detected as continuously active beyond an expected threshold, the control interprets this as a stuck or blocked button condition and locks out machine operation entirely to prevent unintended commands from being executed.

The most common hardware cause is a physical button that has become mechanically stuck in the depressed position, often due to food debris, grease, or moisture intrusion beneath the keypad membrane or button actuator. In other cases, the UI board itself may have a failed switch component or a short circuit on the signal trace connected to a specific button input, causing the control to see a permanent contact closure even when no button is physically pressed.

Diagnosis begins by pressing each button on the panel firmly and releasing it, as a partially stuck button can sometimes be freed this way. If that does not clear the fault, partially loosening the fixing screws that secure the UI board can relieve mechanical stress on the board or keypad membrane that may be causing a false contact. If neither approach resolves the error, the UI board has likely failed internally and requires replacement to restore normal operation.
