Fred, sounds like it's out of alighnment, my kitchen slide has done it since I bought it 3 years ago. You can release the bell stop and it will open or do as I do, when it clicks try hitting the button in the opposite direction until you hear a clunk, then it should open. Have had mine to the dealer three times and it works for a while then back to the same old problem. I've just learned to live with it, retirement does that to you.
