Hardwire chimes randomly ring with Doorbell Pro

After installation of a Doorbell Pro with an existing digital chime, the doorbell seems to work as advertised. However, the chimes randomly ring (usually at night) without the doorbell being pushed—in fact, the Ring Doorbell / app does not ring and has no awareness of the chimes going off. The chimes are Heath-Zenith (HeathCo) 3300-RX and are on the compatibility list and correctly work when the doorbell is pressed. The power to the doorbell is Good and I have carefully checked to ensure there are no shorts or bare wires to cause the chimes to ring.

Hi @Sharon4kay. Good call on checking the wiring to ensure everything looks good on that end. I would also recommend ensuring that the Pro Power Kit is properly installed as well. If everything looks good with the Pro Power Kit as well and the chime kit continues to ring without the Doorbell being pressed, please give our support team a call at one of the numbers available here so they can take a more in-depth look and troubleshoot appropriately.
