If your wired doorbell doesn't work, it could be a malfunctioning button. The weather often damages the electrical contacts inside the casing, and this causes the doorbell to malfunction. Luckily, doorbells are simple devices you should be able to fix on your own. Here are some tips for replacing a malfunctioning wired doorbell button. All wired connections must be installed to code, and you may need a permit. If you are unsure of electrical codes, contact an electrician.

Shut Off the Power and Gather Tools

For this repair, you need the following:

  • a screwdriver
  • two clothespins or two clips
  • a marker
  • a scratch awl or drill for surface-mount doorbell buttons
  • silicone adhesive
  • a voltage meter

Before you make any electrical repairs, shut off the power to the doorbell at the circuit breaker or fuse box, then turn the fan off at the wall switch. Doorbells don't have much voltage going to them, but you still don't want to chance being electrocuted. If you don't know which breaker or fuse controls the bell, you will have to keep switching them on and off until you find the right one. To be certain no voltage is present, test the wires with a voltage meter.

Disconnect the Old Doorbell Button

Doorbells buttons are mounted to the surface or recessed in the siding or door frame. Loosen the screws with the screwdriver and pull the button out, taking care not to damage the thin wires. 

Remove the terminal screws behind the old button and disconnect the two wires attached under the screws. Keep the wires from sliding down the wall or behind the siding by placing two clothespins or clips on them. Pull the button completely off and discard it.

Install New Doorbell Button

Secure the new button on the two terminal wires, wrapping the stripped wire ends to the right on the terminal screw, then tighten the wires down on the screw. Wrapping the wire ends to the left will push the wires out from the screws as you tighten the screws on the wires. 

Coat the edge of the replacement doorbell button with silicone adhesive before you attach it to the mounting surface or push into the opening. Silicone adhesive keeps moisture out of the button and out of the walls.

Press the new button in the hole and secure it with the screws. Don't make the screws too tight, or you could damage the button. If your new doorbell button has a mount, mark the wall for placement of pilot holes and place holes with a scratch awl or drill.

Turn the power back on to test the doorbell for proper operation. For further help, contact a representative from a service like Direct Current.
