If your Ring Video Doorbell is not ringing correctly or is no longer working, use the [[Ring Video Doorbell Won't Turn On|Ring Video Doorbell Won’t Turn On problem page]] for possible causes and solutions.
Most likely, this is a faulty battery problem. A Ring Video Doorbell requires at least 3,900 mV. Check the voltage received by the Ring device by opening the Ring app, selecting ‘Ring Pro’, and selecting ‘Device Health.’ If the Device Health page tells you that the Ring is not receiving sufficient voltage, use this [https://support.ring.com/hc/en-us/articles/208267686-Installing-the-Ring-Pro-Power-Kit-with-your-Existing-Doorbell|Ring support page] to make sure that the Ring Pro Power Kit is properly installed.
If your Ring Video Doorbell is plugged in, receiving sufficient voltage, and is not turning on, the device’s battery may be defective. Replace the Ring Doorbell’s battery using this [guide|95362|battery replacement guide].
