What is preventing the chime sound? How do I troubleshoot model C105
Thank you for your question on the model BK105 wired door chime. You should be able to wiggle the tone bars inside the BK105. That is what helps produce the chime tone. If the tone bars are tight and you cannot wiggle them, they will give you a clunking sound. If you cannot loosen the tone bars, the chime will probably need to be replaced.
