How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing the control area.
- Check power: Confirm the oven is receiving full line voltage and that lights and elements work normally.
- Inspect control board: Remove the rear panel to access the EOC. Check for loose connectors to the display and any signs of heat damage.
- Reseat connectors: Disconnect and reconnect the display ribbon or harness to ensure a solid connection.
- Replace EOC: If the display remains dim or blank and power is confirmed, replace the EOC/display assembly as a unit.
