Opener shows E14; door will not move; occurs after a collision with a vehicle or object while the door was moving.

Safety first: If the door or tracks are visibly bent, do not attempt to force the door open or closed with the opener. The door could come off its tracks.

• Step 1 – Inspect door and tracks: Look for bent sections, rollers out of track, or twisted brackets. If damage is significant, call a garage door technician.
• Step 2 – Check opener rail: Inspect the B&D opener rail for bends or kinks. A bent rail can cause binding and must be straightened or replaced.
• Step 3 – Examine door arm and brackets: Ensure the door arm is not bent and that the header bracket above the door is firmly attached.
• Step 4 – Reset opener: After correcting mechanical issues, disconnect power for 1 minute, then restore. Re‑learn travel limits if required by the manual.
• Step 5 – Internal drive check: If the rail and door are straight but E14 persists, internal drive components (gear, carriage) may be damaged. Have a technician open the unit and replace damaged parts.
