Garage door opens or closes only a short distance (e.g., 10–30 cm) and then stops without an error code.

Safety first: Ensure the door path is completely clear before reprogramming travel.

• Inspect limit hardware: On mechanical limit models, verify the cams are tight on the shaft and the switches click reliably.
• Reset limits: Follow the Nice manual to erase and re‑set open and close limits. Typically you move the door to full open and full close positions and store them.
• Run full learning cycle: If your model supports automatic travel learning, initiate the procedure and allow the door to complete full open and close cycles without interruption.
• Check for obstructions: Make sure nothing contacts the door at the extremes of travel during learning, or the controller may store incorrect limits.
