Burning smell or visible smoke from opener housing during or after operation.

Critical safety warning: Immediately disconnect power at the breaker or unplug the opener. Do not attempt to operate it again until inspected.

• Step 1 – Visual inspection: After the unit cools, remove the cover and look for burnt components, melted insulation, or charred PCB areas.
• Step 2 – Do not energize: If you see any damage, do not reconnect power. The unit requires professional service or replacement.
• Step 3 – Check door mechanics: Have the door inspected for binding or spring failure that may have overloaded the motor.
• Step 4 – Replace opener or major components: In most cases of internal burning, replacing the entire B&D opener head or motor/board assembly is the safest solution.
