Possible Causes
Loose or oxidized keypad ribbon cable, Failed touchpad membrane, Defective electronic oven control board, Moisture intrusion into control panel
How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker before opening the control panel.
Step-by-step checks:
- Access control panel: Remove the screws securing the control panel or backguard. Carefully tilt it forward to expose the EOC and keypad ribbon.
- Inspect ribbon cable: Unplug the flat ribbon from the control board. Check for cracks, discoloration, or corrosion on the contacts. Clean gently with isopropyl alcohol and a lint-free cloth.
- Reseat connectors: Firmly reconnect the ribbon cable, ensuring it is fully inserted and locked. Check all other harness connectors to the EOC.
- Test operation: Restore power and test keypad functions. If F5 returns or some keys do not respond, the keypad/touch panel is likely defective and should be replaced.
- Replace EOC if needed: If a new keypad does not resolve the issue, replace the EOC.
