The fan on my Miele fridge freezer is not working, how do I rectify this issue

probly the evaporator coil in fridge all frozen up you need to pull all the back out inside the fridge section and defrost with air drier

SOURCE: Fridge too cold

There is a damper motor that is behind the vent where you feel the cold air coming out in the fridge section.  That damper should open and close after making temp. adjustments.  See if you can look in the vent and see if it is wide open.  Set your freezer on the coldest setting and check this vent again an hour or so later.  If it is still wide open then that damper motor is bad.  Let me know if you find something different or have any questions.

Have a look at page 5 (KFN8767 Miele refrigerator) it may be similar. Exact model number didnt find.

SOURCE: Hotpoint Mistral Frost Free Fridge freezer - fridge not getting cold

We have just had to call out an engineer to get our 1 1/2 year old Hotpoint Graphite Frost Free Fridge Freezer repaired. The fridge had almost entitely stopped cooling even when on high. I was amazed at how easily the problem was sorted. The engineer removed all the basktes from the freezer to access the screws on the inside backpanel of the freezer. Once this panel was removed it was clear that the so called Frost Free doesn't really mean what it says. The ice need to be melted with a bit of simple care. It is obvious that with a bit of care it is easliy a diy job BUT PLEASE BE CAREFUL AND READ THE NEXT PART BEFORE YOU BEGIN TO REMOVE THE ICE> The ice forms around variouys pipes etc and he usecd a screwdriver to help release the ice quicker than waiting for it to defrost and he also used a simple hairdryer to help speed up the process. He had a ntowel and a basin to take care of the water. Next time I would have no problem doing this myself but I would need to leave it a little while to defrost and NOT USE A SCREWDRIVER as I am sure somehow I would puncture a pipe or the wall of the freezer itself and I am quite used to doing the odd bit of DIY. On a difficulkty scale of 1 to 10 with 10 being difficult I would rate the job as about a 3. Hope this helps anyone who reads this about £70.

SOURCE: Hi i have a hotpoint mistral plus fridge freezer,

hi is this the frost free version ??? if it is which i think it is it could be a fault with temp module{frost free have electronic modules to control the system rather than a old fashioned bog standard thermostat inside the fridge} the fans should be controlled by the module in case of frost free models it could be the module which is playing up
