Refrigerant movement can produce liquid-like sounds during normal operation. A gurgle alone does not establish that water is leaking inside the cabinet.
What the observation tells you
Separate what you hear from what you can actually see. Liquid on the floor, a new chemical smell or loss of cooling requires further attention even if a gurgling sound can be normal. Do not remove rear covers to investigate the tubing.
A useful next step
Record whether the sound is familiar or newly louder and whether temperatures remain suitable. Describe any visible moisture independently. Repairs involving the sealed refrigerant circuit are outside this service's stated work scope.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
