Hello Eddie, Something does not make sense. See if you can see anything jamming it or the gears not lined up or too far apart right under the dancer platform. Or do I need to take it to a shop. My husband is furious that I messed this up for the first time in twenty years of ownership. But as the weights drop midway the clock starts running slower and halts when the weight drops all the way down. Now the pendulum is stuck and will not swing. It used to play only on the hour and half hour.
The issue really depends on if the cuckoos match the hour.
Cuckoo Pendulum Won’t Stay Swinging
You can see what it usually looks like. Just recently we purchased 3 different antique clocks and I was intrigued to pull out the old cuckoo clock to see if I could get it running. Is there a sensitivity adjustment for this? A kid accidentally pulled the chains of my cuckoo clock. Hi Jim, Try tugging gently down on the music chain just in case there is a kink somewhere. Without the weight of the pendulum, the clock will run very fast. You should be able to remove the back and see that chain is on wheel.
