The barrels are what you pull the pins out of on the hinge...working them is kind of bending slightly to make them not so straight but just enough ...
Yeah, I pulled the door off and worked the barrels of the hinges and it worked. Just clean up the barrels and q-tip the barrels and it should work.
I have a bedroom door that won't stay open. It used to but because of a couple squeaks when we closed the door, we lubed the hinges and guess what?...
