If you are talking about water in the pan under the refrig this is normal. It is where the melted ice goes during the frost free cycle. The cooling fan evaporates it before the next cycle.
This is about CARS AND TRANSPORTATION MAINTENANCE AND REPAIRS NOT "refrigeraters" which is misspelled.
Sign of either thermostat failing or fridge itself lost it cooling liquid resulting in no cooling/ freezing. Other potential issues are normally power failure?nor compressor drive failure.
Unless it's a cheap fix such as no power? Or thermostat failed? It's cheaper normally to have entire unit replaced.
