Re: Beko CDA539FW-2 combo
there are 2 sensors that control temperature within the unit
one is in the freezer compartment but I think this is one of the units where the second sensor is under the insulation put on in manufacture. Some engineers have been able to change these but it involves cutting a hole in the back of the freezer (being careful not to puncture the evaporator) then placing the sensor and then using spray foam to seal it in
maybe one of the fridge boys can confirm this but that what the tech info looks like to me
