Possible Causes

Safety first: Disconnect power and secure the door before tightening hardware.

Steps to try:

Tighten hardware: Check all bolts and screws on the opener mounting brackets, rail supports, and header bracket. Tighten as needed.
Inspect rollers and hinges: Replace worn rollers and tighten hinge screws on the door sections.
Check rail alignment: Ensure the Novoferm rail is straight and not striking the door or header.

Persistent loud impacts may indicate structural issues with the door; consult a door specialist if unsure.
