Hello, I have an old indesit refrigerator (model GR 1 400WEU) with a non-separate freezer compartment. I accidentally forgot the door open overnight and now it doesn't cool at all (for the last few days or so). There is no frost in the fridge (as everything has melted since then, the light bulb is working when I open the door and I can hear the compressor running.



What might be the problem? Thanks a lot in advance!
