Everything is installed per instructions, setup and working, but the second interior mechanical chime (the one without the power pack) has a constant low buzz. Annoying. Any ideas for how to eliminate the buzz in the second interior mechanical chime?
Hi @OSUAE. What specific doorbell model do you have installed? What is the model of your mechanical chime kits? What is the voltage rating on your doorbell transformer? This information will guide us in providing accurate troubleshooting information.
