Symptoms
- Pressing buttons does nothing
- Some buttons work while others don't
- Touch controls (on newer models) don't register at all
- Display, if present, is blank or frozen
Likely causes
- CommonGrease film over touch or button controlsA layer of grease can prevent buttons from making contact or block touch sensors from registering a press.
- CommonPhysically stuck buttonGrime can gum up a mechanical button so it doesn't fully depress or release.
- PossiblePower issue to the control boardA tripped breaker or loose internal connection can make the whole panel unresponsive.
- PossibleFailed control boardElectronic touch panels can fail outright after years of heat and grease exposure.
What to do
- Turn off power at the breaker before cleaning around the control panel.
- Wipe the entire control panel with a degreasing cleaner and soft cloth, working into any button crevices.
- For mechanical buttons, gently work them by hand after cleaning to free up any stuck grime.
- Restore power and test each button or touch control individually.
- Check the breaker again if the whole panel, including the light, seems unresponsive.
- If cleaning doesn't help and only the controls are affected (fan/light still work via another method, if available), the control board may need professional replacement.
