The answer to 'why is my ceiling fan' is that there are several common causes for a malfunctioning ceiling fan, including electrical issues, mechanical problems, and even user error. Symptoms can include the fan not turning on, running slowly, making strange noises, or not responding to the remote or wall switch.
Some common causes are a blown fuse or tripped circuit breaker, a faulty motor, worn-out bearings, or a loose mounting. In many cases, these problems can be diagnosed and fixed by a handy homeowner, but more complex issues may require the expertise of a professional electrician.
