Right side door (refigerator) would not stay closed

completely removed door, then replaced worn-out cam on bottom of door-simple enough; then removed hinge from bottom of refrigerator; removing old cam required drilling out the rivet that fastened cam to hinge; secured new cam to hinge with small machine screw and nut. This procedure is relatively easy but does require minor mechanical ability and having a small drill and bit set. However, replacing the two cams totally fixed the problem.
