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

By Dave Rongey - Summary:

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!
