Power at Ring Pro doorbell

When the Ring Pro doorbell is rung the power drops and it has to be reconnected. Is it the doorbell or the transformer

This sounds like a power loss concern. Checking factors like power supply, chime kit, and wiring is the best first step. I put together this Checklist for the Ring Pro which will cover the above and many more steps to consider during installation or troubleshooting. I hope this helps! :slight_smile:
