Replacement of patio door roller assembly

A handy person from Alameda CA says:
Hi, My sliding patio door stopped closing properly. I replaced the roller assembly on both sides of the door even though the rollers seemed to be fine. However, the door is still misaligned. What is my next step?
Here is the part description: 13180 - Roller Assembly, 1-5/16", Plastic, Concave, Non-Adjustable

I'm not sure what the problem might be. Are the interlocks between the sliding door and stationary door bent? That might cause the door to not close properly. Also check the track for any dents near the end of the door where it goes into the jamb.
A quick learner from Alameda, CA says:
Thanks for the reply. I cleaned and checked the track and the door itself when I installed the new rollers. Nothing looked out of ordinary. My wife told me to think about it and she was sure something would appear to me. Nothing did. However, four days later, after a bit of cold weather, the door slides perfectly! No idea why, but happy. Thanks again.
