Novoferm garage door opener runs for a second and then reverses direction without reaching the end of travel.

Safety first: Disconnect power and secure the door before working on tracks or rollers.

Steps to try:

• Inspect tracks: Look along both vertical and horizontal tracks for bends, dents, or misalignment. Gently straighten minor bends and tighten loose brackets.
• Check rollers: Spin each roller by hand. Replace any that are seized, wobbly, or cracked.
• Clean tracks: Remove dirt, stones, or hardened grease from the tracks. Do not lubricate the track running surface; only the roller bearings and hinges.

After restoring smooth manual operation, reconnect the opener and test. If the symptom persists, the force settings or control board may need adjustment or service.
