Bathroom Exhaust Fan Electrical Troubleshooting
Background: Chris, a Handyman from Battle Ground, WA

Question: I have a heater fan, exhaust fan, light combination in my bathroom. The heater fan has its own breaker, and so does the exhaust fan. The light is connected to the bath and hall breaker. Yesterday I went to turn on the heater fan and got nothing.

*I flipped the breaker.
*Pulled the heater fan and checked in a working outlet. It works.
*Busted out the multimeter and pulled the switch. The switch tests fine. Checking the voltage at the wires with the switch removed. I read between 50 and 78 volts. The voltage from the hot wire to ground is 117 volts. I double checked the wire nuts in switch box and I have good connection.

I’m running out of ideas here.

Dave’s Reply:
Thanks for your electrical question Chris.
Chis – It sound like this calls for some troubleshooting. Other things to look for: Loose neutral or power splice connections and at the panel.
