Water can travel over shelves, trim or the exterior before collecting at its lowest point. The puddle location alone may not be the source.
What the observation tells you
A leaking food container in the fridge, a dispenser spill and melting freezer ice can produce different paths. Follow only what is visible through normal access; do not reach behind wet electrical areas or dismantle liners. Avoid tasting liquid to identify it.
A useful next step
Photograph the accessible trail and record when it appeared. Protect the area and seek help for unexplained recurrence or water near electrical connections.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
