Magic Chef oven shows F11, often associated with keypad or control communication issues.

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

• Check for stuck keys: With power on, press each key individually. If F11 appears when a specific key is pressed, that key is likely shorted.
• Inspect keypad membrane: Remove the control panel and examine the keypad for physical damage, bubbling, or liquid intrusion.
• Reseat ribbon cable: With power off, disconnect and reconnect the keypad ribbon cable at the EOC, ensuring a snug fit.
• Replace keypad assembly: If keys remain unresponsive or F11 persists, replace the membrane keypad / control panel assembly.
• Replace EOC if keypad is good: If a new keypad does not resolve the issue, replace the electronic oven control.

When to call a technician: If the glass touch panel must be separated from the frame, professional handling reduces risk of breakage.
