A popping noise is coming from my fan.

Airfoil noise occurs when airfoils are not tightened to the specified torque. Disconnect the fan from power and disassemble the cage. Tighten the airfoil hardware to 29 ft·lb (39.3 N·m). Replace the cage before connecting the fan to power. If popping still occurs, contact Customer Service.
