HOW TO REPLACE A DOORBELL
1. Turn off the breaker that supplies power to the doorbell.
2. Carefully remove the doorbell switch from beside the door. Remove the mounting screws
and gently pull the switch and wires away from the hole through which the wires exit the
house. Use a circuit tester to ensure the power is off.
3. Secure the wires so they cannot accidentally slide back into the hole and disappear.
4. Disconnect the wires from the switch.
5. Connect the wires to the screw terminals on the new switch. You don't have to concern yourself about which
wire goes to which terminal—it doesn't matter.
6. Remove the tape from the wires, and feed them back into the wall so the new switch sits against the area from
which you removed the old one.
7. Mount the switch using the screws provided.
8. Locate the old chime unit inside the house and remove it by taking out the mounting screws. Again, pull the unit
away from the wall and secure the wires to prevent them from sliding through and disappearing behind the wall.
9. Remove the wires one at a time. Apply a small piece of tape to each
and label the screw terminal location from which it was removed. The
terminals should already be labeled on the unit itself. Discard the old
10. Remove the cover from the new chime unit. Thread the wires
through the base of the unit and install the base against the wall using
the mounting screws provided.
11. Connect the wires to the appropriate terminals using the labels as a
12. Attach the cover to the chime unit and restore power to the circuit.
Handy Hints for Installing Doorbells
You can buy pushbuttons and chime boxes together in a kit or separately, depending on your needs.
When running wire for the doorbell, take a measurement of the length from your pushbutton location to the
transformer, and then add about 15 feet to the measurement. This additional cable length will help provide you
with some leeway as you route your cable through twists and turns.
