Wiring a Bath Exhaust Fan Speed Control
How To Slow Down or Control a Bath Exhaust Fan: Bathroom Exhaust Fan Speed Control Options. Options when an exhaust fan is too fast and a slower speed is needed, or a variable speed will work better.
Bathroom Exhaust Fan or Extractor Fan
Electrical Question: My exhaust fan moves too much air can I use to make it a 2-speed fan?
- When I renovated our bathroom and I put in a new exhaust fan.
- The only problem is that we need it on when showering and it moves too much air.
- Is there a switch that I can use to make it a 2-speed fan?
- I would like to have it on 1/2 speed while showering and still be able to get the full power when needed. Would a dimmer switch work for this?
This electrical repair question came from: Ken, a Handyman from Calgary, Canada.
Thanks for your electrical wiring question Ken.

Control Options for a Bathroom Exhaust Fan
- Options when an exhaust fan is too fast and a slower speed is needed, or a variable speed will work better.
- A two speed switch would only work with a two speed motor, however a variable speed motor control might work if the speed control is compatible with the exhaust fan motor.
- A lighting dimmer switch will not work as a speed control for a motor because it has a different control circuit design.
