New Wired 2nd Gen Doorbell Won’t Stop Blinking Yellow

[MrJohnQuinn]

I just bought the new Nest Doorbell Wired 2nd Generation. I installed the chime connector puck and connected my transformer that says it is 16 V with no other information. I assumed it probably met the requirements so decided to give it a try. I previously had an original Nest wired Doorbell installed back in 2016 but it recently said not online, so I decided to buy this new generation doorbell to replace it.

Anyway, when I connected the Nest Wired Doorbell, it was a solid blue status. As I went to add it to the app, it successfully found the WiFi, and was going through the normal set up when it was updating, then stopped and the app said that it needed to be reset. After trying to reset the doorbell, all I get is a blinking light. Now the yellow light continues to blink no matter what I do—even when taken off of power—and it won’t let me do a factory reset. My understanding is the chime should still work even if there is not enough power but it did not work either. I've unplugged it, tried to do a factory reset and all I get is a blinking yellow light even with no power connected to it. My old Nest doorbell worked great for years, so I must have enough power. Why won't it factory reset? I am trying to determine whether or not this indicates a defect in the doorbell. 

Thanks.

A flashing yellow light means "Insufficient power" - "Your doorbell isn't getting enough power. You may need to upgrade your transformer to one that is rated for 16-24 V AC, 10-40 VA to provide enough power to your doorbell."

Some posts in this forum seem to indicate the 2nd gen doorbell may require more power. Many of us have upgraded to a 16V 30VA transformer for both 1st and 2nd gen Google Nest doorbells.  We upgraded our VERY old transformer because our 2nd Nest Hello doorbell wouldn't ring the doorbell chime.

Thanks for the quick reply and advice. I don’t think I could even find my transformer (I think it may be behind drywall in my basement ceiling.). So, even though I meet the specs for the 2nd gen, I guess I will have to go back to a First Gen nest, or find a different option. Weird that it would work for a long while and then stop working.
