Overall height does not establish where the refrigerator and freezer doors divide. Existing furniture panels must suit the replacement appliance's specific installation arrangement.
What the observation tells you
A mismatched split can cause panels to interfere with each other or with the appliance doors. That is not something to correct by forcing a hinge or trimming an arbitrary edge. Cooling performance and furniture compatibility are separate questions.
A useful next step
Use the complete installation specification before considering replacement. For the current repair, describe which panel catches and its relationship to the inner doors. New installation work requires an appropriate separate arrangement.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
