How To Troubleshoot And Repair A Silent Doorbell

"Ding-dong!" used to be the sound coming from your now silent doorbell. Now, you press the button and scratch your head wondering why it won't ring. You may want to try to fix the doorbell yourself or you may decide to call a professional. No matter who fixes the doorbell, these are some of the common problems to check in the process.

The Button

The button that is pressed by visitors to activate your doorbell could be the problem. You can check your doorbell button by pressing it and listening for a buzzing sound. The sound may be faint, but you should hear it even though your doorbell isn't working. If you do not hear the buzzing noise, you have a broken button.

You can also test out your button by disconnecting one of the doorbell wires from the button. Then, touch the disconnected one to the end of the other wire and see if your bell works. If it does, you simply need to replace the button.

When you go to the store to buy a new button, be sure that you bring your old button so that you can match the size up properly.

The Wiring

The wiring for your doorbell could be bad and cause it not to ring. Remove the button and inspect the wiring. The two wires should be securely attached to the button and not loose. If you see that they are loose, tighten them up and test your doorbell button again.

If the wires are not loose or you tightened them and the doorbell still isn't ringing, you will have to investigate further. You can use a multi-meter to test the wiring from the button to your chime. Set the meter to voltage, remove the chime, and connect those wires to the meter. Have someone push the doorbell button. The multi-meter should indicate activity by a moving needle. If the needle doesn't move, the wiring is damaged and will need to be spliced or replaced.

You can also check your chime box wiring using the same method. Remove the chime box and connect its two wires to the multi-meter. Have someone press the button and see if the needle moves. If it doesn't, you will need to hire an electrician, such as one from Alpine Electrical Construction LLC, to repair or replace it as this job involves circuitry.

Determining what is making your doorbell not work will require you to check multiple things one at a time. If you are comfortable in this element, all, except for the chime box, are relatively easy fixes that you can do yourself. Otherwise, call a professional and they can diagnose and repair your problem quickly.
