Even a clean gasket may not contact evenly; compression, residue or latch adjustment can leave gaps.
Check the pattern. Review a repeated near-door temperature pattern alongside gasket contact.
Inspection order
After cleaning, check the full perimeter for cuts, residue and permanent deformation; compare contact marks and latch pressure with the door shut.
