Got a Siemens fridge freezer, a few months ago the freezer lost temp, went up to -5 or so for a few days, then started working normally again. Yesterday came down in the morning and it was +3, once again transferred what I could to my freezer that I use as overspill (or used to), ate huge amounts of ice cream and the freezer once again returned to normal although fluctuated between -12 and -18 for a while.
Out shopping for a new one and apart for Currys there does not appear to be any retail shops selling fridge freezers anymore.
So out of curiosity, anyone knows what might be wrong with it.
