Decko opener light flashes but door does not move when using wall button.

Safety first: Disconnect power before working on low-voltage wiring.

Check wall console features:

• Some Decko wall consoles have a lock or vacation button. Press and hold this button for several seconds to toggle the lock mode off.
• Observe any indicator LEDs on the console; a steady or blinking pattern may indicate lock mode.

Bypass wall control:

• At the opener head, remove the two wall control wires from their terminals.
• Momentarily short the two wall control terminals with a small insulated jumper wire. If the door operates, the wall control or its wiring is faulty.

Inspect wiring:

• Trace the wall control cable for staples or damage and replace if necessary.
• Replace the wall control with a compatible Decko wall button if the wiring is good but the switch does not function.
