Video Doorbell Pro 2 damaged compatible chime NuTone BK115LWH-1

I installed Video Doorbell Pro 2. I have compatible chime BK115LWH-1 as listed in supported chime list. I changed my existing transformer c905 (16V,10VA) to Hampton Bay Branded Wired 16V/30VA Doorbell Transformer.

It worked all fine for one day. Next day I smelled something burning and opened Chime which was humming continuously. I see plastic piece on plunger has melted.

Have anybody face this issue? What should I do next?

Hi @AD4. The Pro Power Kit also needs to be properly installed along with the Doorbell Pro 2, and you can find installation instructions in our Help Center Article here to see how that’s done.
