High-pitched squealing or grinding noise during door travel.

Safety first: Do not place fingers between door sections or near rollers while operating.

• 1. Lubricate moving parts: Apply a silicone or lithium-based garage door lubricant to metal rollers, hinges, and bearing plates. Avoid over-spraying tracks.
• 2. Inspect rollers: Replace rollers that wobble excessively, have flat spots, or do not spin freely.
• 3. Check track alignment: Ensure tracks are parallel and properly spaced from the door edges to prevent side loading.
• 4. Test operation: Run the door several times to work in the lubricant and confirm noise reduction.
