Yeah. The LED sounds less likely now that I think about it. It wouldn't act as a short unless the current limiting series resistor had failed, and if that happened the LED should burn out and go open, stopping the chime.
Once I accidentally connected a LED to 12V without a resistor. There was
an immediate POP sound and half the plastic around the LED disappeared.
