Wall console LED flashes four times and opener will not respond to remote or wall button.

Safety first: Unplug the opener before removing covers. Support the door with the full spring system; do not rely on the opener to hold the door.

• Reset travel limits: On many Wayne Dalton models, there are open and close limit adjustment screws or electronic set buttons. Follow the specific model instructions (usually on the cover or manual) to reprogram the open and close positions.
• Inspect limit mechanism: Remove the opener light lens and cover to access the drive shaft. Look for plastic limit cams or a limit switch assembly. Ensure cams are not cracked and are engaging the switch levers.
• Check wiring to limit switch: Verify the small harness from the limit switch or encoder to the logic board is fully seated and not damaged.
• Test operation with light load: With the door disconnected (pull the emergency release and move door to full closed), run the opener. If it runs normally without the door attached, the limits may have been out of range due to door binding.
• Replace faulty components: If the limit switch does not click or show continuity when actuated, replace the limit switch assembly or encoder module with a compatible Wayne Dalton part.
