I have above american fridge 7 years.
The freezer side is not cooling enough.
Its set to -18c, and reports this as the temp in the freezer, but if i power off and back on it will read true say -4C (tested with thermometer), and gradually descend gradually on the display to -18c all the while internal temp is -4c.
Ive tested freezer fan -ok, no ice behind panel, cleaned out condenser and vents with airline.
Left the door open and allowed temp to rise and it will bring it back to -4.
Fridge works fine at 4c all the time.
With power freeze it will still only go to a max of -10 and fall back to -4 once normal running .
Anyone any ideas
