OK...doorbell went out. Changed the doorbell button...no luck. Changed the chime...no luck. Transformer is dead but I can't find it! It's not in the garage and I have a finished basement so I can't see up in the ceiling. I'm afraid the previous owner maybe closed it in when they finished the basement. I also looked in the attic but there's about 10 inches of blown in insulation and you can't see anything. I fished around and followed all the wires I could find but no luck.
Any ideas of where this thing might be hidden? I thought they were typically located in the basement.

Should I be worried about a dead transformer sitting somewhere? The 16V secondary side is dead but it would still have 120V going to it. Of course whatever circuit it's on would have a breaker behind it.

I guess I'll have to get a wireless one if I want a doorbell.
