Can a light dimmer be used as a speed control for a ceiling fan?

Using a light dimmer as a speed control for a ceiling fan is not advisable. Most standard light dimmers are designed specifically for resistive loads, such as incandescent lighting, and are not equipped to handle the inductive loads presented by ceiling fans. Ceiling fans require special fan speed controls, which are engineered to adjust the power delivered to the motor safely and effectively.

When a standard dimmer is applied to a ceiling fan, it can lead to improper operation of the fan, including potential motor overheating or damage. The fan may also produce undesirable noise, and the performance will likely be inconsistent and inefficient.

In residential wiring and electrical projects, it’s essential to utilize equipment specifically designed for the intended loads to ensure safety, functionality, and compliance with electrical codes. This is why the answer clearly indicates that a standard light dimmer should not be used with ceiling fans.
