The answer to 'why is my ceiling fan hot to touch' is that a hot ceiling fan is often caused by an issue with the motor or wiring. This can be a sign of a problem that requires attention to prevent further damage or even a fire hazard.
Some common causes of a hot ceiling fan include a worn-out motor, loose or damaged wiring, a faulty capacitor, or even an overloaded circuit. If the fan is running at a high speed or has been running for an extended period, it's normal for the motor to get warm, but it should not be uncomfortably hot to the touch.
