Buying notes
Is this the right fit?
- Good fit when
- Use this when a wired doorbell, chime, or compatible video doorbell needs the listed low-voltage power supply.
- Look at another option when
- It is not needed for wireless-only systems, and it should not be guessed at when the existing wiring or voltage is unknown.
- Range reality
- Check the listed compatibility and placement notes before ordering. Building layout often matters as much as the product rating.
- Setup note
- Confirm voltage and VA requirements before ordering. Turn off power before wiring, and use a qualified electrician when the transformer is inside an electrical box or panel.

Great company and website
My doorbells were not working, so I figured the transformer was the problem. This one arrived quickly, was a good price, was easy to install install, and works perfectly.
Haven't used the transformer as yet - keeping it for future problems. Have installed the two doorbell buttons. I had hoped to swap out the inner mechanism with the old cover (which was spray painted to match house trim) but the two were not compatible. So, went with the nickel finish. Thought the new circuit board was for digital system (marked + & -) but it worked with 16 VAC just fine. In fact the LED on circuit is very bright and easy to see and should last longer than the old incandescent bulb. Had to drill out the screw holes as new screws were bigger in diameter. Am I being too picky? Anyway, I'd buy it again.

Do you have to buy a transformer? Looking to replace current doorbell with a louder one.
Good morning. All of our wired chimes operate off of a 16 volt transformer. As long as your current transformer is 16 volts and your original chime was working, you would not need to replace it. Thank you, Customer Support Team 1800Doorbell
