My clock is set to play and strike on the hour. It correctly strikes the correct number of times except at 9PM. At 9PM it only strikes once. It is set to strike from 8AM to 11PM and all other times are correct. Any help would be appreciated.
John, that is an unusual problem. I feel it has something to do with the auto night off feature. It sounds like there is a lever or cam that is bent slightly that is binding at that particular time, inhibiting the rack to fall to the 9:00pm strike position. I have also experienced clocks with a very fine line between working and failing that a slight temperature variation that will make a difference. This is due to an adjustment being at the limit of functioning. It would probably be be best to have an experienced clockmaker look at it. Sorry I could not help you more, but I would have to work with it for a while to see what is happening.
