Hi Paul, More than likely, one or more of the damper rail hangers have come undone from the rail. Remove the action and take loose the end brackets and you can slide out the rails to inspect. Repair by new hanger and soldering and or braising and filing down smooth and bending the hangers to adjust form uniform lift. Hope this helps. James Grebe R.P.T. of the P.T.G. St. Louis, MO.
