How do I check the Voltage for my old doorbell transformer?

You can use a standard Multimeter to check the voltage for the wires at your Door Bells. The voltage should measure between 12~24VAC. If the measured voltage is less than 12V AC, we recommend changing old doorbell’s transformer with a Multi-Voltage Wired Doorbell Transformer or using a 12VDC, 1.0A AC/DC adapter. If you need to know how to use a Multimeter, follow the WiKiHow® for How to Use a Multimeter.
