Thank you for reaching out to us. Your roller assemblies might be the culprit. Based on the information on the sticker, you have a Better Bilt patio door that goes back to 1990 to 1999. You might have the 81-090 rollers but this is just an educated guess. I recommend you remove a roller assembly to confirm the specifications align with ours.

To loosen the screws, you can use WD-40.
