What to check if a ceiling fan is not working?

If a ceiling fan is not working, check these items in order to systematically isolate the problem. First, check power sources: verify the wall switch is in the on position, check the circuit breaker panel for a tripped breaker, and check if any GFCI outlets in the room or adjacent bathroom have tripped, as fans are sometimes wired through them. Second, check the remote control if your fan has one: replace the batteries, ensure you are within range, and try the wall switch override if available. Third, check the pull chains: make sure the fan speed chain is not stuck in the off position and the light chain is pulled fully. Fourth, turn off the breaker and inspect the ceiling canopy: remove the canopy cover and check that all wire nuts connecting house wires to fan wires are tight and not burnt. Look for a loose or disconnected remote receiver module. Fifth, listen for clues: if you hear humming, the motor is getting power but the capacitor or bearings may have failed. If you hear nothing, power is not reaching the motor. Sixth, check the capacitor, a small black box inside the switch housing, for bulging or leaking. Seventh, check for a tripped internal limiter or thermal fuse. If all wiring checks out and the fan still does not respond, the motor or receiver likely needs replacement.
