Bathroom Exhaust Fan Electrical Troubleshooting
Background: Chris, a Handyman from Battle Ground, WA
[ad#block]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.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

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 that I use to easily Detect 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.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
