Dust on an exhaust grille may contribute to dirty surfaces and noise. Broan-NuTone recommends powering off and gently cleaning accessible parts. Ceiling-mounted fans and shared building systems vary; do not dismantle motors, ducts or wiring without professional authorization.

0 / 6 done

Read the model manual to learn whether its grille is user-removable.
Turn off the fan and isolate power at the breaker where directed. Use a stable step stool for ceiling work; do not overreach.
If removal is allowed, release the grille gently following the instructions without bending springs or forcing plastic clips.
Remove grille dust with a soft brush, vacuum or barely damp cloth. Wash only parts the manufacturer says can be washed, and dry fully.
Never spray water or cleaners into the motor, controls, wiring or duct. Ask a professional if the blower must be dismantled or unusual noise persists.
Reattach the completely dry grille securely, restore power and listen for unexpected vibration or noise.
