I needed a break from building a Pottery Barn knock-off, so I decided it was time to finally install a bathroom exhaust fan timer switch! Previously, it was a regular switch like so -
From left to right it went 'Light above the shower', 'Light above the toilet', 'Exhaust fan which is part of the light above the toilet'. Like most people, I'd either forget to turn it on while showering, which eventually does Bad Things to your ceiling and walls, or I'd forget to turn it off, which eventually does Bad Things to your electric bill and the environment. So, I went to Orange!
Here's what I came home with -
I took off the faceplate and unscrewed the switches so I could get at all the wiring in the box. Like so -
Don't you love my instructions taped to the wall? I know, it's genius!
So, I ran downstairs, into the garage, and hit the breaker. Back upstairs, into the bathroom...Leftmost switch turns the light above the shower on, huzzah! The other two don't do anything, bummer. So I turned the breaker off again, and took a quick break (did some more work on that mirror, and then consulted Google). Found this video - http://www.youtube.com/watch?v=FY5XMgZ1ScI and that was when I figured out about the blue versus black wire and the neutral issue.
Now I just need to do the Little Boy's bathroom as well. His fan doesn't get used as much, but it IS something that would be nice to have. I think I'll wait a week to see if the house burns down first though.
/ETA - The timer was 20$, the other pieces were just of couple dollars each. The second to the last picture shows the new white neutral going to the bundle of neutrals.
