The answer to 'ceiling fan not working' is that there are several common causes, including a faulty motor, loose wiring, or a problem with the wall switch or remote control. Symptoms may include the fan not turning on at all, the fan spinning slowly or intermittently, or the fan making unusual noises.
Some potential solutions include checking the circuit breaker, inspecting the wiring for any loose or damaged connections, and replacing the wall switch or remote control batteries. If the issue is with the motor itself, you may need to replace the entire fan unit. For most ceiling fan repairs, it's generally best to call a licensed electrician, as working with electrical systems can be dangerous for DIY homeowners.
