Hey Simsan I also get the knocking noise and my fridge also freezes food too. It seems we all have the same problem. I have read a post by an engineer on the net which claims that the whirlpool has a design fault in the cooling unit which causes it to ice up and make the polystyrene all soggy and then the fan stops working. Try defrosting I have heard that this works. The engineer replaced my fan unit but a month later it has gone again and the engineer can't come until after Christmas!

Hi I have the same problem as Freya with my whirlpool fridge freezer and Christmas is approaching fast! Unfortunately mine is a lot older so no come back on sale of goods act. I have already paid out within a year of having the fridge a lot of money to an engineer to fit a new circuit board so am loth to go there again. For what was a very expensive piece of kitchen equipment at the time it is rubbish! I will never by a Whirlpool anything again and am seriously thinking of dumping this one. Does anyone know what is actually wrong with it - is it the thermostat? My water dispenser also does not produce any water and makes a loud knocking noise when pushed although ice is still being produced.
