Guardian opener rail or motor housing vibrates excessively and transmits noise into the house.

Safety first: Disconnect power before tightening or modifying mounts. Use proper ladders.

• Tighten all mounts: Check and tighten opener hanging brackets, header bracket, and rail joints.
• Add vibration isolators: Install rubber isolation pads or vibration-damping brackets between the opener and ceiling joists.
• Ensure clearance: Make sure the rail is not touching the ceiling or other framing members.
• Check door balance: If the door moves in jerks, have a professional adjust springs and hardware.
