Novoferm garage door opener does not move the door after a power cut; the carriage is disengaged.

Safety first: Ensure the door is fully closed before attempting to re‑engage the opener.

Steps to try:

• Re‑engage carriage: Pull the emergency release cord toward the opener (or as specified by Novoferm) and move the door manually until the carriage clicks back into the trolley.
• Test operation: Restore power and operate the opener. The carriage should now move with the rail.
• Inspect latch: If the carriage will not stay engaged, the latch mechanism may be worn and require replacement.
