Before writing off the control board entirely, rule out the simpler explanations for an unresponsive panel.
Clear the Control Lock
Most ovens include a lockout feature that disables the panel entirely.
Fix: Hold down the lock or clear button for a few seconds to release it.
Power-Cycle the Oven
A brief electronic glitch can lock up the panel until power is interrupted.
Fix: Cut power at the breaker for about a minute, then turn it back on.
Suspect the Control Board
If the panel remains dark or unresponsive after that, the membrane switch or the control board itself has likely failed.
Fix: A technician can test the affected component and replace it.
