Wall clocks can add a decorative finish to a room. Wall clocks come in a variety of forms--some have a pendulum, some have a balance wheel inside the clock and others feature a cuckoo that springs out from within the clock every hour. Some wall clocks have no pendulum or cuckoo but feature a scene or a saying printed on the face of the clock. Fixing your wall clock depends on what is wrong with it.
Wind your pendulum or balance wheel clock with the key provided when you bought the clock if the pendulum has stopped swinging. The key fits into the winding mechanism on the back of the clock. After you've wound the clock, take the pendulum and sweep it up to one side until you hear a click and then let go. The pendulum should start swinging. Pendulum and balance wheel clocks are driven by a powerful spring that needs winding periodically.
Look to make sure the hands on your wall clocks are not touching. Touching hands will stop the clock from working. Pull the hands apart and reset the wall clock.
Make sure pendulum clocks are level. The pendulum will not swing if the clock is not level. If you have moved your clock or if the clock has been pushed or jarred while on the wall it may not be level. Push one side of the clock a bit and listen to the ticking sound. Gently push the other side. Keep pushing each side until the ticking has a perfect tick tock sound.
