Do all wired doorbells need a transformer?
Is a transformer required for all doorbells? Yes. Doorbells are low-voltage applications and they will not work without a transformer.
How long does a doorbell transformer last?
Doorbells are often taken for granted, because these durable units can last 10 years, 15 years, or more without ever experiencing a glitch. But an outdoor location means that these electrical devices are exposed to all of the elements: broiling sunlight, rain, snow, sleet, and wind, to name a few.

Although the cost could range from around $200 to $350, you can rest assured that the job will be done correctly and according to electrical code.
How hard is it to replace a doorbell transformer?
A doorbell transformer converts electricity to a lower voltage, then sends the current to the doorbell’s other parts. Often enough, replacing a faulty transformer is a fairly straightforward job. Turn off the power first, disconnect the transformer’s wiring, and dismount it.
How does a doorbell transformer work?
A doorbell transformer steps down the 120 or 240-volt AC electrical power to a lower voltage, typically 10 to 24 volts. The transformer’s other terminal connects to one of three terminals on the signaling device. Another terminal is connected to a wire that travels to the other terminal on the button.
