My Clock Keeps Stopping: Part Three – Cuckoo Clocks


Did you know that most of the time you, as the clock owner, can correct the problems that cause your mechanical cuckoo clock to stop? That’s why we’ve posted these troubleshooting tips. However, if your clock stopped because the chains slipped off the gears or there’s a buildup of dirt and oil, you’ll need professional help to get your clock running again.

Here are six easy things to check:

1. Is the clock hanging straight on the wall?

If your clock looks like it’s not hanging perpendicular on the wall, plum it up, then give the pendulum a gentle push to get it swinging again. Then listen for a steady, even beat. The silent space between the tick and the tock should be the same. If it isn’t, carefully tilt the clock slightly to the left or to the right until the ticktock rhythm sounds even.

2. Is the door latch blocking the cuckoo door?

A small wire latch (door lock) can get in the way of the cuckoo door. Make sure it’s not preventing the door from opening.

3. Is the bird’s lifting wire out of place?

Check inside of the clock case to make sure the lifting wire (attached to the top of the bellow) is below the bird’s tail and not on top of it or on the side of it. If needed, gently move the wire under the bird’s tail.

4. What’s the position the shut-off switch?

Check the shut-off switch to make sure it’s not in the “on” position. Even if it appears to be “on”, move it in both directions. Sometimes the switch can be somewhere in the middle of “on” and “off” and if it is, then the clock may not work.

5. Is the clock wound?

Forgetting to wind any clock is the most common reason it stops working. All mechanical cuckoo clocks are powered by the gravitational force of its weights, which drop slightly with each swing of the pendulum. When you wind your clock, the weights are lifted back up so they can begin their drop again and keep your clock going. As you wind, don’t lift the weight with your other hand in order to help it along. Instead, let the chain support the full load of the weight and keep winding until the weights are at the very top.

6. Are the hands touching each other?

Have a close look at the hour and minute hands to see if they’re contacting each other. If they are, gently press the hour hand slightly back toward the clock dial, making sure it doesn’t touch the dial. If the hands still touch each other, slightly bend the minute hand toward you. This should create the needed clearance space.

So, if you’ve found any of the above problems and have fixed them yourself, congratulations!
