i have a similar problem. had a power outage and when the power was restored the doorbell would continuously ring, escalating in volume. i just unplugged it! any suggestions?
If you push the buttons (try both front and back doors) does the doorbell reset itself and then work normally.
A doorbell power failure indicator that causes it to ring continuously is not a good idea because no one might be home and the sound would give away the fact the house is unoccupied.
