Step 5: Test Chime

Remove the chime's cover. Leave the multimeter on the voltage setting and touch the probes to the wires. Have a helper push the button. If the multimeter shows that current is flowing but the chime doesn't ring, replace it (Step 6). But if there's no current, the wiring is faulty. If you can find the break, make a splice with 18-gauge wire. If you can't, either pull through new wires or install a battery-powered wireless unit.
