Re: Freezer working fridge is not
I have a fridge that has two completely isolated and separated circuits and compressors for the fridge and freezer parts. In such a case the diagnosis is rather easy.
If you have a single-compressor model, you have an issue with the regulating system that controls how much heat is extracted from the individual compartments. Although in such case you would expect at least something to happen in the fridge part.
It will take a technician to figure out if you have an issue with the temperature sensors, the circuit board, the compressor(s), or any actuators.
