Display shows “E”, operator beeps or flashes but does not move

Safety first: Ensure the door is safely supported and cannot fall. Keep hands away from pinch points.

Step-by-step:

• Check emergency release: On Hormann operators, pull the red release cord toward the door to disengage, and move the carriage to the engagement position. To re‑engage, move the door manually until the carriage clicks back into the drive shuttle, or follow the specific re‑engagement instructions.
• Inspect door arm: Confirm that the curved or straight door arm is firmly bolted to the door and to the carriage bracket.
• Test: Once re‑engaged, apply a command. The door should move with the operator. If the carriage will not lock, the release mechanism may be broken and require replacement.
