During this hot spell I haven't altered the setting on my fridge dial (have always had it around 7 [out of 10]).
It's seemed to be chucking out more heat from the back than usual and when I looked just now behind the food on the top shelf, the panel that normally has a bit of frost on it has got snow - over 1cm deep!
My milk didn't seem that cold just now - advice please on how to restore the fridge to happiness quickly!
