Do not improvise a new supply arrangement to keep a suspect appliance running. Follow the manufacturer's electrical requirements and have a faulty socket assessed by a qualified person.
What the observation tells you
An extension can be unsuitable for the appliance or location, and it may conceal the distinction between a supply fault and an appliance fault. A cable stretched across a kitchen also creates mechanical and trip hazards. Never bypass a protective device.
A useful next step
Protect the food using suitable alternative storage while the electrical issue is resolved. Explain whether other equipment on the same supply was affected, without repeatedly reconnecting the fridge to demonstrate tripping.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
