The two seals can differ in size, profile and attachment even on one appliance. A model reference alone may still need the exact door position specified.
What the observation tells you
Ordering the lower seal when the upper door is affected creates an obvious mismatch, but a similar-looking profile can be misleading too. Some doors use a construction that changes the repair approach. Do not cut a nearly matching gasket to size.
A useful next step
Provide the full model, the affected compartment and a safe photograph of the damaged section. Confirm compatibility and repair suitability before purchase, and keep closure concerns under assessment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
