Display shows F5, oven may not start or may stop mid-cycle, keypad may seem unresponsive.

Safety first: Disconnect power at the breaker before removing the control panel.

• Check for moisture: If a spill or steam recently hit the control panel, allow it to dry completely (several hours with power off). Sometimes the code clears after drying.
• Inspect keypad ribbon:
  • Remove the back cover of the control console.
  • Locate the flat ribbon cable from the keypad to the control board.
  • Unplug and inspect for corrosion, cracks, or burnt spots.
  • Clean contacts gently with isopropyl alcohol and reseat firmly.
• Test keypad: If available, use the built-in keypad test mode (refer to the tech sheet behind the control panel). If certain keys do not respond, the keypad/touchpad is defective.
• Replace failed component: Replace the touchpad/control panel assembly if the keypad is faulty. If the keypad tests good but F5 persists, replace the electronic oven control board.
