We have a new doorbell with Westminster chimes that is hard wired.
When you push the door bell button and release it the door bell chimes
the first bell, but stops. If you hold the door bell button in, the
bell will ring through the entire 8-note chime. Does it sound like it
is miswired or defective. The brand is Heath Zenith. Thanks!

did you replace transformer?

chimes need more voltage........
