Dead as a Door...bell

Can you tell the difference between these two pictures? It's more obvious in person:

On the top, our doorbells is glowing. On the bottom, it isn't.

Right around when we were getting the electrical work redone for our new room, our doorbell stopped working. There had been a short - the crew admitted to that. Though they didn't think the two were related.

Well whatever it was, we now have no electrical power to the doorbell, which had magically just worked, emitting a constant glow and chiming an actual manual bell.

Our electrician friend managed to get it working partially - one of the two bell tones seemed permanently fried but the other started working  if the whole unit was loaded up with C batteries. So we got a "ding" instead of a "ding dong." That seemed a decent fix.

 The problem was that it was short-lived. Within a week or two, the doorbell was dead again.

Apparently the constant glow sucks up 4 C batteries in about 10 days. Obviously not something we wanted to sustain.

So we're back to no doorbell. This has not been a bad thing what with a newborn napping at various points of the day. But because it's there and people expect it to work, it has also meant that we haven't always answered for people we actually want to see, like our neighbors (by now I think most of them know it's broken). I probably at least should put a little sign on it or a piece of tape.

The options now are to purchase a fake add-on bell or pay an electrician to fix it, which might involve a whole new unit and new wiring. Neither are great solutions. Since the builders for the new room denied it was related even then, I don't think we can convince them now to come fix it, so we are on our own for whatever costly solution we decide on.

But I miss that glow...
