Nest Doorbell Gen 2 Wired not ringing Chime Inside

[Myata92]

I installed a Nest Doorbell Gen 2 Wired yesterday. It's located where the doorbell was which rang the mechanical chime inside before installation. I upgraded the transformer to 16VAC-30VA. Unread 18v at the transformer and at the chime itself. The doorbell will ring touching the wires together at the nest but not when connected. Front door only setup. The puck is connected to the front and transformer on the chime. I've tried all the settings (on/off, electric chime, etc) nothing. The video and audio work perfectly and notifies my phone when rang on the Nest Doorbell but it doesn't ring the chime inside at all.

Is your chime connector wired as shown in the Help topic below?

If so, I've seen a few posts from other customers in this forum who had chime connectors for the 2nd gen doorbell that were defective.

It is connected like the first picture. 

I chatted with support and they told me to hire a professional to look at the system, then contact them again if the issue persists to get a replacement sent. I don't want to pay for a technician when everything works without the nest and doesn't with it. It's connected correctly, correct voltage, correctly installed puck. The nest is either not telling it to chime or the puck is bad.

It does seem you've covered every possibility.  I've never heard of Google Nest requiring a professional visit before replacing a Google Nest doorbell.

As I mentioned, I've seen other posts from customers who discovered they had a defective chime puck for their 2nd gen doorbell.  Most of the reports indicate Google Nest sends a replacement for the entire doorbell, not just the chime connector, and some customers install the new chime connector and send back the new doorbell and old chime connector to avoid the hassle of having to reinstall their doorbell.

We have three 1st gen Google Nest Hello Doorbells, and upgraded to a 16V 30VA transformer several years ago, so you've got that base covered.

I'm assuming you have the "Indoor chime" option turned on in the Google Home app for your doorbell

I'm having the same problem. Installed a 2nd generation doorbell and the app works fine, but the doorbell chime won't ring in the house. We bought the second generation doorbell to replace a first generation doorbell that had the same problem when we installed it. The power to the unit is fine.

I contacted Google chat again today. They had me disconnect the chime connector and try the doorbell again. The doorbell worked indicating a problem with the chime connector. They said to return to Lowes where I bought it and try a new one. 

For experimentation, I reconnected the chime connector except this time I connected the two wires in reverse (front to transformer, transformer to front) and the inside chime worked. Maybe a random glitch but everything is working as it should with the connector installed.

My system is 1 front doorbell with two mechanical chimes inside wired in series (downstairs chime connected to upstairs chime). Transformer is the Zenith 16VAC-30VA. The chimes are older chimes from when we bought the house but still work with the Nest Doorbell. Settings on the App are Ring Indoor Chime set to on, No Electronic Chime.
