How to Wire an Exhaust Fan Switch
[ad#block]Electrical Question: I am trying to help a friend who lives in a condominium apartment. I am a handyman and know a few things about electricity. He asked me to help solve this electrical problem. The exhaust fan in his laundry room came on for no apparent reason. The switch that controls it was off but it started operating and would not turn off at the switch. I removed the switch and tested it for continuity and it is functioning properly. I even tried replacing it with a new switch but the the fan always keeps running.
This switch is in a box that has another switch which only controls the light in the laundry room. What is the solution?

This electrical question came from: John, a Handyman from Toronto, Ontario, Alabama

John, it would be good to identify the make and model of the exhaust fan that is installed, as there are several types. Some exhaust fans have built in sensors that will activate the fan when heat or high humidity conditions occur, and it is possible that a built in sensor can malfunction. It seems obvious that the exhaust fan does have a direct supply of power to it which is controlled by another method which needs to be identified, and this can be understood once the make and model number is available. Another possibility is that there is another switch that controls the exhaust fan, and I can’t help question if the switch you have worked with actually does control this exhaust fan.
