My living room lights can be controlled on/off by two switches in my house.
On the weekend, I tried installing a dimmer switch in one of the switch locations and now they aren't working properly. The switch that I didn't replace can turn the lights on/off just fine. The dimmer switch which I've replaced only turns the lights on/off if the other switch is in a certain position. The dimming function itself works fine. Does anyone know what I need to do to make this work properly?
I've tried multiple wiring scenarios to no success. Do I need to check the wiring on the other switch as well? I assumed I didn't considering it worked fine before.The new dimmer is a 3-way switch and the other switch is too.
