Wireless Doorbell Repair
Keep that doorbell ringing (doorbell image by fafoutis from Fotolia.com)

Wireless doorbells are ideal for the do-it-yourself person who would prefer to keep projects simple and avoid drilling holes and working with electrical wiring. These doorbells are also more preferable for renters who would not want to spend their own money to install an electrical part they may not be able to take with them when they move. In the same way, most landlords have restrictions within their rental agreements that forbid such alterations to their existing structures. Wireless doorbells are easy to install, inspect and fix.

  1. 1

    Open the chime case (the box you hear the doorbell ring from). Inspect the batteries you installed when you mounted the doorbell. Check the expiration dates on the sides of the batteries. Look for other signs of battery damage like escaping battery acid that has formed a white crust.

  2. 2

    Place both batteries in the palm of your hand, if you don't see cracks or lost battery acid. Close your other hand around the batteries, shaping your hands like you are about to pray. Briskly rub the batteries together and back and forth for a few minutes. Wipe off the battery posts that hold them in place. Install the batteries back into the chime case. Press the doorbell button to check for the tone. Replace the batteries if you hear a weak tone or no tone. The batteries are weakening and losing their strength, or they are dead.

  3. 3

    Depress the doorbell button and see if it bounces back to its place when you release it. Remove the doorbell button cover if it does not bounce back. Examine the button assembly for what may be preventing it from resetting.

  4. 4

    Lay the open doorbell button case and the chime case next to each other with the jumpers in both pieces visible. Check the jumper alignment. Match them exactly. Make sure they are on the same channel (the seven jumpers are aligned the same).

  5. 5

    Observe how close you have mounted the doorbell to concrete. Do not limit your doorbell's range by mounting it close to concrete. Make sure your button and/or chime case are not mounted on or near metal. Doing so limits the doorbell transmitter range as well. Move your chime case mounting spot if it gets direct sunlight. Again, this will limit range. Consider moving the chime case and button closer to each other if they are 10 or more feet apart.

Tips and warnings

  • Date your battery installations, and remember that their life expectancy is about 12 months.
  • Be careful with manipulating the doorbell's jumpers; this can nullify your warranty.
