How to Wire an Exhaust Fan Switch
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?

Exhaust Fans and Switch Wiring
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.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
