Ring Gen 3 Doorbell does not ring NuTone BK125LWH-1 Door Bell. Its on the supported list. I know the door bell works as I can touch the 2 wires together and the door bell works. When connected to the Ring 3 , and you push the ring button, it does not activate the doorbell’s ding-dong inside the house.
Hi @whawkusa. Try resetting your Doorbell by holding down the reset button underneath the setup button for at least 20 seconds. After the reset is done, follow the steps under Set Up a Device to reconnect your Doorbell to your wifi network. Verify that the wiring looks correct and the wires on the back of the Doorbell are connected firmly. If it’s still not ringing your internal chime kit, please give our support team a call at one of the numbers available here.
