Hoping that someone else can enlighten me. Had above since last October. Set the temps digitally to 4 for fridge and -18 for freezer. Everything fine until a few weeks ago. I noticed that the temp for the freezer fluctuated between -18, -19 and -20. At first I thought it might be something to do with the hot weather - thinking perhaps it had to adjust itself. However, it has continued doing this even tho' the weather is cooler. It was -20 this morning even tho it had been cool all night, later it went to -19 and now it is -18 again. I have rung Miele and they said someone would come end of next week to look at it. The fridge doesn't change. Has anyone else had this problem? Would like to know. Thank you.
