Novoferm garage door opener runs but the door will not fully open, stopping short of the header.

Safety first: Ensure the door cannot hit overhead objects or the opener rail when fully open.

Steps to try:

• Check for obstructions: Inspect the top of the door travel for brackets, pipes, or ceiling objects that may be hit.
• Adjust open limit: Use the open limit adjustment on the Novoferm control head. Increase the open travel slightly and test until the door clears the opening fully without hitting the stops.

Do not set the open limit so high that the door hits the opener rail or bends the top section.
