My hotpoint mistral plus 8596 lcd at front of the fridge is flashing at 15c - it should be 4c - I have changing it but it reverts back to flashing 15c - the section between the fridge and the freezer is very hot and i cant hear the slight humming noise anymore - is it worth repairing or should I get a new one - I have had the fridge for 11 years.
