Introduction
A doorbell that doesn't ring has four possible problems: the button, the chime, the transformer or the wiring that connects them all. Here's how to track the culprit and make the fix.
Inspect the Wiring
Inspect the wires for damage. Repair breaks with twist-on connectors. Splice in new wire to add length and allow for connections.
Clue!
If you have hardwired doorbell buttons at the front and back of your house and one of them works, you can be sure that the non-working button or the wiring connected to it is bad.
Bypass the Button
Unscrew the doorbell button to remove it from the wall. Loosen the screws on the back of the button and disconnect the wires. Then touch the two wires together. If the chime rings, the button is bad. If not, the chime, transformer, or wiring is bad.
Replace the Doorbell Switch
Connect the wires to the new button, or doorbell switch, just as they were connected to the old one. Screw the button to the wall and you're done.
Check the Chime
Remove the chime cover and check for voltage while a helper pushes the button.
Chime Armature
If the tester lights up but the armatures don't move, clean them with rubbing alcohol.
Test and Replace the Doorbell Button
As you test the doorbell components, you don’t need to turn off the power. The doorbell transformer takes the household voltage of 120 and typically reduces it to around 16 volts for doorbell operation. Though you can leave the power on as you test, turn it off before you begin replacing any of the doorbell parts.
Replace the Doorbell Chime Unit
The doorbell chime unit is usually located in a place inside your home where it’s easy to hear. It might be on a wall in the living room, hallway or other high traffic area.
Replace the Transformer
While replacing the transformer can be a DIY project if you have experience working on similar repairs, you may want to call an electrician for this fix.
Check the Doorbell Circuit
While it is possible to identify and fix a tear in the doorbell circuit wires, you might prefer to hire an electrician to make this repair.
