The doorbell stopped ringing, the chime buzzes, or the new video doorbell keeps rebooting. Most of the time the small transformer that powers it is dead or too weak. We find it, test it and replace it.

Next Phase Electric replaces doorbell transformers in homes across South King and Pierce County. The transformer is a small box that turns house power into the low voltage the doorbell and chime run on. Older houses usually have a 10-volt transformer, which is enough for a plain button but not for most video doorbells, which want 16 to 24 volts. Transformers hide on a junction box near the panel, or in the basement, crawlspace, attic or garage. Finding it is often the longest part; the swap itself is usually under an hour.
From a dead chime to a video doorbell that will not stay on.
No sound from the chime. We test the button, the chime and the transformer, and replace whichever one has failed.
A transformer with the voltage and power your video doorbell asks for, so it stops rebooting and dropping off Wi-Fi.
A chime that buzzes all the time or a transformer that hums usually means a stuck button or a failing transformer.
Behind the panel, in the crawlspace or above a ceiling. We trace the wire from the chime until we find it.
Three things decide whether it rings, and whether a video doorbell stays on.
Plain chimes run on about 10 to 16 volts. Most video doorbells need 16 to 24, and a weak transformer is the most common reason they misbehave.
Volts are not the whole story. A video doorbell also needs enough power, rated in VA, which its maker lists and the transformer prints on its label.
It sits on a junction box, wired to house power. We mount the new one where it can be reached and label it.
The job is the same. The transformer is not.
| Plain doorbell | Video doorbell | |
|---|---|---|
| Voltage | About 10 to 16 volts. | Usually 16 to 24 volts. |
| Power | A small transformer is enough. | More power (VA), as listed by the doorbell maker. |
| Signs it is too weak | A faint chime, or none. | Rebooting, Wi-Fi drops, a chime that will not ring. |
| Fix | A same-size replacement. | A larger transformer, sometimes a chime kit too. |

Two things set the price: how long it takes to find the old transformer, and whether the chime needs anything too. Once it is found, the swap is a short job. You get the exact price before any work starts.
Usually on a junction box near the electrical panel, or in the basement, crawlspace, attic or garage. In some houses it sits at the chime itself. We trace the wire until we find it.
Most need 16 to 24 volts, and enough power (VA) as listed by the maker. Many older houses have a 10-volt transformer, which is too weak.
A weak transformer is the most common cause: the doorbell runs short of power when the camera, Wi-Fi and night lights all draw at once. The fix is a transformer sized to the doorbell.
Often, but not always. A stuck or broken button, a failed chime or a broken wire look the same. We test each part before replacing anything.
It connects to house wiring on a junction box, so the circuit has to be off and the box closed properly afterwards. If you are not comfortable working on 120-volt wiring, it is a short job for us.
Yes. We can install the doorbell, set up the chime and connect it to Wi-Fi in the same visit.
