Steps
Switch off the power to the bathroom fan at the breaker box before you touch anything. Tape the breaker off so no one turns it back on.
Set up a step ladder under the fan and remove the cover. Most covers pull straight down or are held by two screws or spring clips.
Vacuum the dust and lint off the fan blades and the inside of the housing. A clogged blade is the most common reason a fan slows or stops.
Check that the blades spin freely by hand. If they drag or wobble, the blade or motor bearing is worn and needs replacing.
Look at the wiring connections and the plug on the motor. Push any loose connector back on and tighten the screws on the wire nuts.
Test the fan by turning the breaker back on and flipping the wall switch. If it runs, switch off the power again and refit the cover.
If the fan still does not run, remove the motor unit. Most are held by one screw or a clip and unplug from the housing.
Take the old motor or blade to the store or match the model number on the housing label, then fit the new part and test again.
Tips and common mistakes
Never work on the fan with the power on, even for a quick check of the blades.
Clean the fan blades and housing once a year to stop dust build-up.
Write down the model number before you shop for parts so you get the right fit.
If the fan hums but does not spin, the motor is usually seized and needs replacing.
Questions
Why did my bathroom fan stop working?
The usual causes are dust clogging the blades, a loose wire connection or a worn motor. Check the dust and wiring first before buying parts.
Can I replace just the motor instead of the whole fan?
Yes, most fans let you swap the motor unit or blade on its own. Match the model number on the housing label to get the correct part.
How do I know the power is really off?
Turn the fan switch on after cutting the breaker. If nothing happens, the power is off. Tape the breaker so it stays off.
