Some of the more common reasons a clock stops chiming:
1. The movement is dirty and/or worn out from years of use and neglect.
2. The clock has not been wound or for reasons correlated to the above, it's been wound but won't operate.
3. Adjustable parts on the chime train have fallen astray and must be readjusted for optimal performance.
4. If it's chain driven, the weights may be on the wrong chains.
5. The clock has a silencer which has been set so the chimes do not operate on purpose.
Photos or a detailed description of the clock and its inner workings will help us further define what's wrong with your clock.
Welcome to the MB. These are a bunch of nice fellows but with such a short
introduction, they couldn't help but tease a little.
First, there is a distinction between strikes and chimes, although both may
used chime rods to sound on.
Chimes are the tunes that play. Strikes count the hours.
Please try to be more specific. If you don't know who made your clock,
pictures of both the clock and movement can help.
Also, what clock knowledge you may have as well.
Most problems where the strike or chime fail to work are problems beyond
someone with no clock repair experience.
These usually require having it repaired at a clock repair shop.
