In answer to your basic question. Yes, you'll probably have to take out the action to "fix" it. How old is the piano? Young Chang (Samick) used to have a plating problem with their center pins which caused them to seize up. Damper underlevers included. If that's the case, take out the action and the underlever and repin it. That's the only real fix. But if you have one, you'll probably have a lot more as time goes on! Otherwise, it could be hanging up on the sostenuto tab or be tight in the damper guide rail bushing. My guess would be the underlever, though.
