Doorbell broken? Missing its cheerful chime? Well, take our quiz and get step-by-step guidance on how to repair it yourself.
What is most likely broken when your doorbell stops working?
the transformer
the bell
the button, bell or transformer
When your doorbell stops working, it could be any part of the circuitry that could have stopped working: the button, bell or transformer.

On how many volts does a doorbell operate on?
10 to 18
A doorbell operates on a voltage of 10 to 18. The transformer's function is to minimize the 100 to 120 volt current to the amount needed for the doorbell to function.
100 to 120
120 to 180

On what parts of the doorbell can you work on without turning off the power?
the transformer
the bell and button
You can work safely on the bell and button without turning off the power; you need to switch off the power if fiddling with the transformer.
the button and transformer

After you pull the doorbell button off your wall and detach the wires, how can you tell if the button is the problem?
Press the button.
Put the bare ends of the wire together.
Put the bare ends of the wire together. If the doorbell rings, you know the button needs replacing.
Examine the wires.

What type of switch is a doorbell button?
three-way
closed
single-pole
A doorbell button is a single-pole switch, meaning that there are two wires attached, and either wire can be attached to either terminal screw.

How should your first try to remove a doorbell cover?
Pull as hard as you can.
Lift it up slightly and then pull it out.
When removing the cover off a doorbell, first lift up the cover and pull. If that doesn't work, pull it out straight, without lifting it up. If that doesnâ€™t work, look for prongs that may be holding it together and gently open them up.
Pull it straight out without lifting it up.

How many wires are there in a standard bell?
two
A standard doorbell has two wires, but the number of wires will depend on the number of chime tones your doorbell has.
three
four

What can be used to test the wires inside the doorbell?
a 12-volt bell or car lamp
The wires need to be tested using a 12-volt circuit tester. Another bell or a car lamp can be used for this purpose.
an 18-volt bell or car lamp
a 20-volt bell

What does it mean if the testing item does not respond when you push the doorbell button?
The testing device is probably broken.
The problem is in the transformer.
If the testing item doesn't work, the problem is probably with the transformer. If it does work, the bell just needs to be replaced.
The bell needs to be replaced.

When you are fixing a doorbell, when should you tag the internal wires with masking tape?
if you have two or more wires
Tag your wires with masking tape if you have three or more wires. This will prevent you from reconnecting them to the wrong terminals.
if you have three or more wires
if you have four or more wires

When fixing a doorbell, what process do you use to work out which part of the mechanism is causing the problem?
deduction
process of elimination
Through the process of elimination, you first determine if it is the button malfunctioning, then if it is the bell and then the terminator.
induction

Where can you find a transformer's voltage and wattage information?
on the package
stamped on the transformer
Once you have confirmed that the transformer is not working by connecting a testing device to the transformer's terminal wires, you will need to replace the transformer. Make sure to purchase a replacement with the same voltage and wattage -- the information will be stamped on the transformer.
on a plastic tag attached to the transformer

What should you use to connect a transformer to the circuit wires of your electrical system?
crimp on connectors or wire nuts
To connect a transformer to the circuit wires of your electrical system, use crimp on connectors or wire nuts. Follow the instruction manual for installing a transformer carefully.
parallel splices

If the transformer or power circuit are working, then what is malfunctioning?
the chime box
the electric system outside your house
the bell wiring
If the transformer and power circuit are working, the only other possibility is that there is a break or loose connection in the bell wiring. Trace the circuit, searching for loose screws or wires.
