Door is very noisy, with squeaking and banging from the door itself rather than the opener.

Safety first: Do not touch torsion springs or cables directly. Disconnect opener power and use caution around moving parts.

• Lubricate moving parts: Apply a light garage door lubricant to roller stems, hinges, and the torsion spring (light mist). Avoid getting lubricant on the tracks.
• Tighten hardware: Use a socket or spanner to snug all hinge bolts and track bracket fasteners. Do not overtighten.
• Inspect rollers: Replace cracked or wobbly rollers with Merlin‑compatible or equivalent garage door rollers.
• Check track alignment: Ensure tracks are parallel and not pinching the rollers. Adjust brackets as needed.
