Garage door opener vibrates excessively and shakes the ceiling during operation.

Safety: Support the operator while tightening or modifying mounts.

• Check brackets: Tighten all bolts securing the BFT operator to the ceiling and header. Replace any stripped anchors.
• Add bracing: Install additional angle iron or brackets to stiffen the mounting if the ceiling is flexible.
• Inspect rail: Ensure the rail is straight and properly supported near the door.
• Check door balance: Have a professional adjust springs if the door is out of balance.
