Kenmore Dryer F09 Error — Control Panel / UI Board Fault
The F09 error code indicates a fault detected in the user interface (UI) board or a communication error between the UI board and the main control board. This error can manifest as unresponsive buttons, an erratic display, or the dryer refusing to start or change settings.
Troubleshooting F09
- Press and hold the Start button for three seconds to attempt a soft reset.
- Perform a hard reset by unplugging the dryer for 10 minutes.
- Inspect the wire harness connecting the UI board to the main board for loose or corroded connectors.
- Test whether specific buttons are unresponsive (stuck buttons can trigger F09 on some models).
UI Board Replacement
If the display is erratic or buttons fail to respond after reset, the UI board has likely failed. This is a relatively straightforward part replacement that our technicians complete in a single visit with model-specific parts.
