How to fix that shy doorbell button or doorbell itself if people are coming to your door and instead of the familiar ding dong or chimes, the only sound you hear is that of knuckles rapping or the door knocker knocking.
There are three parts to a doorbell: The doorbell button, the doorbell itself which most of the time includes the transformer and the wiring.
The Doorbell Button.
In my experience, this is not only the easiest to repair, but it is the most common reason doorbells refuse to obey your finger. Obviously, if the button itself is pushed in and does not pop back out, say the return spring is broken or the button has lodged itself in and won’t show its face, the best thing to do is replace it.
Doorbells usually run on low voltage direct current as contrasted to your household electricity which is generally higher voltage and is alternating current. This means that although it is safer to work on the doorbell than the regular household electrical system, I always advise DIY’s to turn off the power to the system they want to work on.
I want you to run one test before turning off the power. Pry, unscrew, or pull the reticent doorbell button away from the wall, depending on how it is attached. (TIP: If you buy a replacement doorbell button, you can “reverse engineer” the installation to see how to get access to the wiring.) Carefully tighten the terminal post screws. Then push the doorbell button. If it works, zip it up by pushing back or screwing back the doorbell button. If it does not work, bridge the terminals of the doorbell button with a flat bladed screw driver. Ding dong. Eureka. If it is still mute, put the doorbell button back into place and turn off the electricity to this system at the panel box.
The doorbell itself, which includes the transformer, is the next easiest thing to replace. Once the power is turned off, open up the doorbell by taking off its cover, unscrewing it from the wall, disconnecting the wires and reversing the process with a new doorbell.
Checking the wiring for continuity is also pretty easy using a continuity tester. However, fixing faulty wiring by trying to replace it can be a gigantic waste of time, not to mention very frustrating. If it is the wiring, you have got a bit of a problem because you cannot realistically fix it by repairing the wiring. Fishing new wiring through your walls using the old wire to pull it works a lot better in theory than it does in my world. I have tried it many times. If I really have to do this, I now solder the new wire to the old and hope that the electrician who installed it in the first place did not staple or tack it in place. I have spent too much time and energy twisting wires together, attaching them together with tape, etc., and having them pull apart inside of the wall to do it without solder.
The Wireless Solution
However, the wonders of modern technology have provided a solution: there are now wireless doorbells that save a lot of wear and tear on both you and the plaster. In fact, unless the problem is a loose connection at the doorbell button (possible) or at the doorbell itself (unlikely), replacing the whole thing with a wireless system is the way to go.
