My cuckoo clock doesn't cuckoo. What should I check?Updated a month ago

If your clock is not cuckooing, check the following:

• Make sure the cuckoo door is unlocked.
• Verify that the clamps have been removed from the bellows.
• Confirm that the clock is turned on.
• The cuckoo bird may be stuck inside the clock.
