Bi-fold door

My single bi-fold door will not stay closed. It's new and was working fine until all of a sudden it will not stay closed in the center. What can I do?

There should be a spring on the side opposite the hinge pins that applies back pressure on the closed door to keep it hyper-extended. It's possible that this spring is either missing, jammed, or lacks it's springiness, no longer holding back pressure on the door to keep it closed.
