- Some buttons work while others don't
- Panel feels sticky or has visible residue
Likely causes
- CommonControl lock feature accidentally activatedMost ranges have a control lock, often engaged by holding a specific button, that disables the panel intentionally.
- CommonControl board temporarily frozenLike other electronics, the board can freeze and need a power cycle.
- PossibleSpilled liquid or grease residue affecting touch sensitivitySticky residue can prevent capacitive touch buttons from registering presses properly.
- PossibleWorn membrane under specific physical buttonsIndividual buttons under a membrane pad can wear out while others continue working.
- Less commonFailed control boardA more serious board failure causes widespread unresponsiveness a reset won't fix.
What to do
- Check your manual for the control lock button combination and try holding it to unlock.
- Unplug the oven at the breaker for one minute, then restore power to reset the control board.
- Clean the touchpad gently with a slightly damp cloth to remove any grease or residue, avoiding excess moisture near the panel.
- Test each button individually to identify if the issue is panel-wide or specific to a few buttons.
- Avoid pressing buttons with wet or greasy hands going forward.
- If specific buttons remain unresponsive after cleaning and a reset, this points to a worn membrane under those specific buttons.
- Have a technician replace the control board or touchpad membrane if the whole panel stays unresponsive after these steps.
