Repairing a doorbell may seem like a difficult task, but it's usually a simple project that only requires a few replacement parts. Most of the electrical components run on a low-voltage circuit, so there's no need to hire an electrician if the unit needs to be rewired.
In this regard, why would a doorbell stop working?
It's usually an easy fix. Start with the doorbell button — in most cases, it will be the cause of the problem. Unscrew the doorbell button and touch together the two wires fastened to the back; if the contact between the wires makes the bell ring, then the button is broken and should be replaced.
Likewise, how do I know if my doorbell transformer is bad? A reading of 16 volts indicates the transformer works properly. Less than 16 volts indicates the transformer needs replacing. Touch each probe of a low-voltage test light to each screw head on the transformer if you are not using a multimeter. If the lamp fails to light, the transformer is bad.
Then, how much does it cost to fix a doorbell?

- Change the multimeter to read 120-volts AC or higher.
- Touch the leads of the multimeter to the input connections of your transformer.
What voltage is my doorbell?
Household current is typically 120 volts for most circuits. A few circuits, such as those for electric clothes dryers, require 240 volts. Since doorbells have such a low voltage requirement, they need a means of converting 120 volt current down to the 8 to 24 volts necessary to operate the chime.

Is a humming doorbell transformer dangerous?
If your doorbell is relentlessly buzzing or humming, the button may be stuck in the contact position. If this continues for very long, the electromagnet in the transformer will burn out. When this happens, the bell or chimes unit won't work even if current is being delivered to it when you press the button.
How does a doorbell get power?
When you press a doorbell button, you complete an electrical circuit that allows household electricity to flow through the doorbell's internal electromagnet. The magnetic field generated by the electromagnet is then used to power a mechanism that creates the doorbell sound. Doorbells are low-voltage devices.
