Cuckoo clock door stuck open
Upon installation of a new cuckoo clock movement this is a common issue. The Cuckoo clock door stuck open could be a number of things. Please check the following to see if it solves the issue of the door not closing all the way.
Weights not heavy enough
If you check all of the below issues, and the door only shuts when pulling the weight down, consider adding a heavier weight. It maybe the wrong pine cone weight to begin with.
Bending the door wire
Bird wires bent
The arm that pushes the arm to make the bird come out, may need to get bent inward some. This may be tricky to see or get to, but sometimes there is a small side door on the side of the cuckoo clock case that can open and see this wire, or arm, that pushes the arm that connects to the bird.
Other times there is no door on the side of the case and need to do it from the back of the movement by taking the back panel off of the cuckoo case.
Correcting a bent bird wire
Right as looking at the back of the movement that is.
In some cuckoos this is even trickier to see or adjust as the right hand bellow tube maybe in the way. Remove it if this is the case.
Locate this horizontal wire that is in the approximate middle of the movement, which is on the strike train side. This is the wire that can get bent.
This bending in of the wire more into the movement, will in turn make the door come out more. If bent out some toward the case side, will allow the bird to go in more and therefore the door will shut more.
