Could be the doorbell stuck in the "on" position, could be the solenoid inthe doorchime unit stuck. The system (usually) works off a 24V transformer, feeding power to the doorbell to make the circuit connection, then to the door chime unit. The doorchime usually consists of one or more solenoids with long centrall rods, which the solenoid throws up against the bell(s) to make the chime. Though there are electronic types, and plain piezoelectric or vibrator "buzzer" types too.


Depending on your electrical capabilities, with a volt ohm meter or by just touching the wire you undid to the chime connection point, you could determine if you are still getting power at the chime (if it works or buzzes again) which would mean the doorbell is stuck. If you only get power there when the doorbell is pushed, then it is probably OK and the chime solenoid or relay is failed.


Sometimes, with the central rod type solenoid, they get stuck due to dust buildup - cleaning (with power off to it) with a small brush, and moving the solenoid up and down by hand to clean off any debris, might free it up. (Do NOT use any oil - dust will crud it up in quick order).


It could be the relay or solenoid is failed - so if it still buzzes after freeing up the solenoid shaft(s) and putting power to it for a second or two, replace the chime unit - around $15-30 for normal units, $30-100 for programmable digital ones (you can download MP3 or iTunes songs to them), up to $300-500 for quite fancy ones with actual hanging chime rods, into the thousands for very fancy ones with a number of organ-like chimes.


Note which wire goes where - they are usually polarized, so hooking up the wire the wrong way will try to drive the solenoid down into itself instead of against the chime.

Oops - in rereading my answer as posted, saw I had succumbed to replying based on what is common in my area - but doorbells / chimes come in 8, 12, 16, and 24V systems that I have seen - so you have to check the voltage or see if there is a label on the doorbell transformer (if you can find it - commonly WELL hidden away under stairs or such).

Even a few out there still on 120V - would not want to push the doorbell button on those in the rain !
