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 Ring Video Doorbell installed back in 2016 but it recently died so I decided to buy this one to replace it.
Anyway, when I connected the Nest Wired Doorbell, it was just blinking yellow, which indicates there is not enough power. Now the yellow light continues to blink no matter what I do. 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 assumption is my transformer probably needs replaced, but is it normal for the doorbell to continue to blink yellow even when unplugged? I assume it has a battery of some sort? Also, why won't it factory reset? I am trying to determine whether or not this indicates a defect in the doorbell.
Sorry to hear that you're experiencing this, and I would love to look into this further for you. 16 to 24 V AC (North America) are the power requirements for the Nest Doorbell (gen 2). It sounds like it could possibly be your transformer, but it seems to have been installed correctly. I would try to follow the factory reset steps once more, just in case. You can learn more about the power requirements here.
