Was getting 12v out but only 6v at both chimes and ring doorbell.
Ring doorbell pro chime humming.
The chime only dings but does not dong or has other unusual behavior.
Essentially you insert the front and trans doorbell wires to the bypass mode wire.
I started by using the 16v 10va transformer that came with the chime.
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.
The hum was there again and at times louder.
I replaced the doorbell chime with a heath zenith 2735 from the approved list same issue.
Disconnected the ring doorbell and reinstalled old doorbell button.
That worked successfully for a couple of weeks.
After some reading i realized that due to the pro power kit any wired chime would more than likely hum.
I ran brand new doorbell wire to support this installation.
I have two ring pro video doorbells connected to a mechanical chime.
But then one of the ring pro s started going offline due to low voltage.
The video doorbell pro doesn t ring your chime but the live stream video and other features still work.
No more buzzing 12v at both chimes and button and doorbell button and chimes work again.
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.
To get a chime connector please call support.
My ring video doorbell 2 is buzzing non stop after working well for 6 months.
You might also hear a constant buzzing sound from the chime.
Your ring video doorbell pro is designed to draw power from the same 16 volt ac power transformer as your internal doorbell mechanism.
My solution was to bypass the chime by wiring the pro power kit directly inline with the ring doorbell.
I then replaced the transformer with a new 16v 30va transformer recommended for ring same issue.
Ring doorbell guide working about 10 15 days ago and guessing from low voltage and not enough to keep the battery charged.
All of a sudden last week after someone rang the bell the chime started vibrating and making a humming noise.
A chime connector may be necessary if.
