    Hi

    I have the C6004APW fridge freezer type K6345NF Serial Number 1610912504.

    It’s just out of it’s 5 year warranty, the freezer is now icing up, it never has done previously.

    I have cleaned and checked the seals, no obvious damage, still seems to have good adhesion/vacuum when opening and closing, no one is admitting to have leaving it ajar at any time.
    The fridge temperatures are all as expected, 3 -5 degrees, depending on where tested in the fridge
    The freezer temperature is running at -28 to -30, which I believe is excessive, I was expecting -18 to -21

    I haven’t stripped it down as yet, as it’s a bit full, but once the hols are over it should be a bit emptier and I’ll do some further investigation, pull the freezer back panel forward and check the condenser for ice.

    For now I am looking for any advice as to possible causes / solutions, that don’t need new bits, and then the best order of approach for replacing and possible faulty sensors etc.

    Fortunately, I can see a sensor grill in the fridge bottom right, and in the freezer top left beside the fan, (still checking the fan, haven’t seen it running yet, so possible problem there)

    I already own and am competent with soldering Iron, and heatshrink etc, so will happily replace and bits that make value for money sense, as the freezer is the perfect size and fit for our needs.

    Would appreciate if anyone can suggest which sensors and part numbers are behind the grills,

    A) Fridge – Bottom Left
    B) Freezer – Top right

    C) ??? Presumably there will be a condenser sensor fastened to the condenser tubes, when I get in there.

    I have pictures, how do I load them here, clicked the image icon and the quota 19.5k is too low for the smallest image I have.


    Any help suggestions appreciated

    Thanks

    Ok so done some more checking.

    This CF6004APW, has two sensors and what appears to be a double thermal fuse (4 wires)

    Had the meter on the Fridge air sensor: 22.8kOhm at 4C, and 10.4KOhm at 24C

    Also had the meter on the freezer evap/defrost sensor 113kOhm at (about) -29C, no access at the time of testing to change the temperature.
    This suggests both thermistors are producing sensible readings assuming they are both 10K thermistors with beta of about 3250

    Also tested the resistance of the in fridge control, which reads for 50Kohm down to 1Kohm in about 10K steps, pretty much as expected.

    Still to test: Evap defrost element, drain heating element, and evap thermistor at more temperatures.

    Reminder symptoms are, freezer to cold -30, and fridge all working OK, if perhaps a little to cool at 2 – 3 degrees, compressor running a lot but does stop occasionally for relatively short periods of time.

    Subject to further tests, and the fact I don’t understand how the good operation of the heating elements would affect the ongoing freezer temperature, bearing in mind I have fully defrosted and cleaned the freezer evaporator matrix and drain. I am almost ready to buy and replace the main control PCB, on the grounds can’t think of what else to check, have obtained another thermometer to check actual temps, and consistent with previous readings.

    Hope this helps anyone else with similar problems, and open to suggestions as to other options to investigate.
    Thanks
