Hello..

My door bell has stopped working correctly. Need some advice before
tearing everything apart..

The button outside is illuminated.. When pressed, light turns off, but
does not trip off door bell unless I press and hold multiple times.
(when doorbell goes off and depress button, the button stays off until
chimes end.. times when doorbell does not go off while holding down
and release, light goes back on..

Don't think it is switch because light works, and turns off when press
down.. so, I think the circuit is being completed to the door bell..

My guess is either transformer or bell itself.. But, if transformer is
not working correctly, no current would be going to the switch,
correct??

Transformer is about 5 years old.. Door bell is OLD..

thanks.
