Default Doorbell?
formulated the question :
They'll be okay, they're only energised for a fraction of a second.

The bell contacts can and do often jam closed, which means a chime type
can remain energised for a very long time. They often overheat melt/
distort the plastic and jam, which might be the OP's problem.
