Doorbell Pro 2 and mechanical chime

My mechanical chime does not ring when my doorbell is pressed. Everything else is working.

Under device health it states “Power Output Level 3” and “Your doorbell transformer is under powered.”

Is that why my mechanical chime does not ring?

If I replace my transformer with the one recommended, should that fix my problem?

Hi @Zorro1. Yes, that certainly sounds like the issue here. If there is not enough power, nothing will operate as it should. You should see a suggestion for a doorbell transformer in the Ring app, or you can visit If you are not experienced with this installation, I would reach out to a qualified electrician.
