Howard miller wall clock (612-477)
The clock keeps great time but hasn't played the chimes for quite some time and I miss them. One of the hammers(the one on top when the clock is laying on its face) moves freely but the one behind doesn't move at all. I know nothing about clocks but thought that it might be something simple. The battery has been replaced. I can hear the click sound when it reaches the 1/2 hour and hour mark but no chimes:( Thank you for any help you can give!
