Nest Wired Doorbell 2nd gen blinking yellow, will not reset

[BC28]

I had a previous gen nest that worked fine

transformer is 8-16V etc.

Now the 2nd gen wired doorbell is not factory resetting just continues to blink yellow even unplugged from any wiring. 
Even in my hand I have pushed the reset hole with a wire and pin and held that for 20-30 seconds multiple times. I’ve stepped away come back an hour later attempted the reset still the bell continues to blink yellow.

Before I change my transformer is this 2nd Gen product a dud.

The reset won't work properly if the doorbell isn't getting enough power. In any case, Nest Doorbell (wired, 2nd gen) requires a transformer that is rated for 16-24 V AC, 10-40 VA.

Upgrade your transformer for Nest Doorbell (wired, 2nd gen) - Google Nest Help

Thanks David. I understand and that’s helpful.

Some feedback to Google:
That sounds like a flaw in the product. If it’s a wired bell but not actually wired up, then the lights shouldn’t be flashing yellow when I have it completely disconnected from any external power source. And since the light is continually flashing yellow unplugged, there must be a small internal backup battery and that should let me reset the bell without an external power source. Anyhow, short of it is the bell is useless without a larger 16-24v transformer and I thought I could sneak my existing 8-16v based on the upper range limit of it.

Hello BC28, 

Thanks for keeping us in the loop, and I'm happy to hear that this has been sorted out. I’ll keep this thread open for one more day. If you need further help, let me know.

Thanks

Hi Edmund have 2 further questions

If I change the transformer do I need to change the chime box. I’m seeing posts that if you don’t match the chime box voltage current specs to the newer transformer, the additional power could blow out the existing chime box

Is google recommending customers also change the chime box? And/or install a wire wound resistor to reduce the additional current from the larger transformer?

[BC28]

Please do not close the thread until I have installed the bell successfully.

I am ordering a transformer and the step down resistor for my chime box.

if that doesn’t work then I will have to order a new chime box.

Those pre-reqs should be in the guide or box. The video bell has additional costs and considerations beyond just the bell itself which can frustrate the customer.

Hi BC28,

It sounds like a plan. If you're using a mechanical chime system, it should work with a transformer that is rated for 16–24 V AC or 10–40 VA. I'll keep this thread open; let me know if it works.

Thanks,
Edmond
