My solution was to bypass the chime by wiring the pro power kit directly inline with the ring doorbell.
Ring doorbell pro chime humming.
Was getting 12v out but only 6v at both chimes and ring doorbell.
I ran brand new doorbell wire to support this installation.
The chime only dings but does not dong or has other unusual behavior.
Disconnected the ring doorbell and reinstalled old doorbell button.
The video doorbell pro doesn t ring your chime but the live stream video and other features still work.
That worked successfully for a couple of weeks.
I ve had a ring video doorbell for about two years now.
After some reading i realized that due to the pro power kit any wired chime would more than likely hum.
I removed the cover for the indoor chime and noticed the metal rod that strikes the plate was vibrating rapidly causing the whirring humming noise.
I started by using the 16v 10va transformer that came with the chime.
I have two ring pro video doorbells connected to a mechanical chime.
My ring video doorbell 2 is buzzing non stop after working well for 6 months.
The hum was there again and at times louder.
No more buzzing 12v at both chimes and button and doorbell button and chimes work again.
Essentially you insert the front and trans doorbell wires to the bypass mode wire.
To get a chime connector please call support.
All of a sudden last week after someone rang the bell the chime started vibrating and making a humming noise.
Ring doorbell guide working about 10 15 days ago and guessing from low voltage and not enough to keep the battery charged.
The internal mechanical doorbell works perfectly the ring does not.
A chime connector may be necessary if.
I just installed a ring pro and connected the power kit to 1 of 2 mechanical doorbell chimes in our 1 year old house with a pre existing 16v transformer.
I then replaced the transformer with a new 16v 30va transformer recommended for ring same issue.
Problems can arise however when a doorbell mechanism draws so much power that there s not enough left over to power your ring video doorbell pro.
I replaced the doorbell chime with a heath zenith 2735 from the approved list same issue.
