Troubleshooting

* If the fan does not turn on, check the following: * Make sure that the power is turned on. * Check the circuit breaker or fuse to make sure that it has not tripped or blown. * Inspect the wiring for any loose connections or damage. * If the fan makes a buzzing noise, the motor may be faulty.
