One of the screws holding my oven door together, fell out and I noticed that the gasket between the outer glass and the door frame needs to be re-installed. It appears to be a fiberglass rope type gasket but each end is frayed and they don't come together unless I stretched them, but then I can't hold them together while I put the door back together. Is there some kind of connector that is missing? Any advice on how to fix or replace this would be greatly appreciated.
