Noisy Dimmer Switch

Question: My dimmer switch makes a humming sound when the light is in the “ON” position. Do I need to replace it?

Answer: Many dimmer switches have a humming sound when in operation. If this is annoying you and the family you can usually solve the problem by replacing the current dimmer switch with a more expensive model. In my opinion, dimmer switches made by Pass & Seymour or Leviton are the best.

Note: It is very common to have humming dimmer switches when the switch is used to control a fan motor rather than a light. There are specially designed speed control switches made for fan controls. Check with the manufacturer of the fan to find out which speed control they recommend.
