Thank you for your question on the model LA14WH wired door chime. The LA14WH is a mechanical chime and should have solenoids, plungers and tone bars inside of it. The LA174WH looks very similar to the LA14, but is an electronic chime and would have a printed circuit board and speaker inside of it. Either way, if you are missing parts from inside of it, you would need to purchase a new unit. There are no internal parts available for them. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.
