You Replaced A Light Switch – Now Things Do Not Work Right

How the Repair what my Husband Just Fixed….now when I turn off the bathroom light it turns off all power to the adjoining bedroom….

Electrical Question from Tim about Light Switch Wiring
Background: Tim, a Homeowner from Coon Rapids, MN
Question: I replaced a double switch (light/fan) in my bathroom and now when I turn off the bathroom light (only) it turns off all power to the adjoining bedroom and to the lights only in the laundry room that is directly below. Why is this happening and how do I fix it?

Dave’s Reply:
Thanks for your electrical question Tim.

You obviously changed the wiring configuration when you replaced the switch. The wiring in the switch box will need to be identified: Power In, Power Out, Switch Legs to the Light and Fan and wired appropriately. It appears that you have wired the power out that feeds the bedroom and laundry through the bathroom light switch.
It’s always interesting to see what you guys are doing out there. It’s nice being a weekend DIY Warrior – Just don’t burn your house down or tick off Mom my turning off her lights!

Electrical Tip

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.
