Do I Need To Turn Off Power To Change Doorbell Transformer? [Solved]
As you test the doorbell components, you don’t need to turn off the power. The doorbell transformer takes the household voltage of 120 and typically reduces it to around 16 volts for doorbell operation. Though you can leave the power on as you test, turn it off before you begin replacing any of the doorbell parts.
