Hello,

Your hinge appears to be the root of the problem, which you may be able to replace with our 36-048 hinge set. Take a look and see what you think. 

If you need replacement operators as well, take a look at the video below to see our experts replace your discontinued operators with our 39-315 and 39-316. Thank you!
