The door opening can collect fibres that interfere with a tidy closure, but aggressive cleaning can damage surfaces or seals. Use the model's permitted exterior and accessible-area method.
Understanding this situation
A soft approved cleaning approach is different from pulling seals away or probing the latch. A door that does not close normally may have a fault beyond visible lint.
A useful next step
Let the dryer stop safely and clean only accessible surfaces as directed. If closure remains unreliable, leave it unused and seek assessment. Do not hold, tape or weight the door shut to complete a cycle.
