Safety First: Disconnect power before removing the control panel or touching the control board.

Step-by-step:

Access the control panel: Remove the screws securing the backguard on your Premier range to expose the EOC and keypad ribbon.
Inspect ribbon cable: Check the flat ribbon from the touchpad to the EOC for kinks, tears, or burn marks. Ensure it is fully seated in the connector.
Clean contacts: Gently remove the ribbon and wipe the contacts with a dry, lint-free cloth. Do not use liquids.
Test keypad response: Restore power and test each button. If some or all keys do not respond or F5 reappears, the touchpad membrane is likely defective.
Replace faulty component: On many Premier models, the keypad is integrated with the front control panel. Replace the control panel/touchpad assembly. If a new keypad does not resolve the issue, replace the Electronic Oven Control (EOC).
Final check: After replacement, verify that all keys respond and that Bake, Broil, and Timer functions operate normally.
