Continuous beeping with F11 displayed; keypad may seem stuck or unresponsive

Safety first: Turn off power at the breaker before accessing the control panel.

• Power cycle: Turn the breaker off for 5–10 minutes, then restore power. If F11 returns immediately, proceed.
• Inspect control panel:
  • Remove the rear control panel cover (backguard) screws.
  • Locate the ribbon cable from the touchpad to the EOC.
  • Disconnect and inspect the ribbon for corrosion, burns, or kinks.
  • Clean contacts gently with isopropyl alcohol and reconnect firmly.
• Check for moisture:
  • Look for signs of liquid spills or steam damage around the control area.
  • Allow the panel to dry completely if moisture is present.
• Isolate keypad vs. board:
  • If possible on your model, power up with the keypad ribbon disconnected. If F11 disappears, the keypad is shorted.
  • If F11 persists with the keypad disconnected, the EOC is likely faulty.
• Replace faulty part:
  • Replace the control panel / touchpad assembly if the keypad is shorted.
  • Replace the electronic oven control board if the fault is on the board.

Note: Some Frigidaire Professional ranges have the keypad and display integrated; in that case, the entire control assembly must be replaced.
