    Above conventional fridge freezer has no internal light bulb ok reed switch switching. when u press fast freeze lights go off and flashes red warning light for a few secs then goes to normal as if just switched on. LEDs go dimmer when door opened. PCB has numbers on it kgk 3 6115 364-01 and kgk_3-C_21L.
    Sensors read 20K and 12K.
    Is this likely to be PCB? not too experienced with Miele. Fridge cold freezer Contents appear frozen.

    My Miele F/Freezer is the type with digital display & controls along the top. When the door is opened its normal for the display to go bright & dims down gradually after door is closed again, it sounds to like theres a fault somewhere in the sensing of the reed sw’ or the magnet on door that activates it. If the fridge door the is left open for a long time on mine the light in fridge shuts off automatically. Its worth trying a magnet to activate reed switch to see if it works. Check cabling back to board & connections to PCB. Miele refrigeration products are mostly made by Liebherr if thats any help for cross reference of spares etc.

    Seamy did that with door and my magnet to prove reed switching with meter. The board appears to go dead and then warning light comes on. Do you have a partnumber price for PCB?
