Gliderol garage door opener vibrates excessively and transmits noise into the building structure.

Safety first: Use a stable ladder and disconnect power before adjusting mounts.

Steps to reduce vibration:

• 1. Tighten all mounts: Check the Gliderol opener head brackets and rail supports; tighten all fixings.
• 2. Add isolation: Install rubber or neoprene pads between the opener brackets and the building structure.
• 3. Check rail alignment: Ensure the rail is straight and aligned with the door centerline.
• 4. Have door balance checked: An unbalanced door can cause excessive vibration; have a technician adjust springs if needed.
