I installed a Ring Doorbell Pro several months ago and it only worked for a day. The app said it wasn’t connected to the internet, so I thought my signal was not strong enough at my front door. I installed a wifi spreader and still could not get the doorbell pro to work. It lit with a white circle but never spun. After several days I contacted support and they determined my doorbell pro was defective and sent me a new one. I installed the new one yesterday and it worked perfectly for an hour… When I checked it that afternoon the app once again said it was offline. However this time there are no lights lighting up on the doorbell at all. It’s as if it is completely dead. The doorbell will ring if I disconnect the pro and touch the wires together but when I connect it back up it will not ring, nor light up. I’m starting to wonder if it has something to do with the power. I did have the pro power kit installed in the ring box inside the home, and have also installed the new one according to the directions. Help!
Hello @SonyaJett ,
Here is a helpful online link to Ring Support:
And from what you described, your issue could possibly be Insufficient Power, because you have some of the Symptoms:
- Regularly losing connection to your wifi network
- Regularly shutting off (the white light on the front will turn off )
- Freezing up during a live event
- Not ringing your existing internal doorbell correctly
- Night vision doesn’t work
- Ring Pro works fine for a couple of events and then stops working
Your Ring Pro requires a power source that supplies a minimum of 16 volts AC.
To check the voltage of your Ring Pro:
- Open the Ring app.
- Tap the three lines on the top left.
- Tap Devices
- Select your Ring Pro.
- Tap Device Health.
For Ring Pro to function correctly, the voltage needs to be listed as “Good” or (when you tap it) at least 3,900mV.
**Note: ** Even if your power source supplies 16 volts AC or greater, resistance in your wires–often due to length or age of the wires–can keep Ring Pro from receiving enough power to function.
I would read the other recommendations in the link and see if they are helpful too.
But if you do determine that your power supply is most likely the cause:

And then, if this all doesn’t correct your issue, I would telephone Ring Support again for help:

Unfortunately, due to the Covid-19, their available hours have been changed also:

I hope this information is helpful 
There are two possible reasons why your light isn’t lighting up: You’re keeping the right button pressed too long. Ensure that you are pressing the button firmly and releasing it immediately without holding it down. Your Video Doorbell Pro isn’t receiving power onevanilla
