Utterly baffled by the seemingly interchangeable terminology on these sensors. Both of these fit my cxf6114s:
Evaporator sensor:

Air sensor:
http://shop.ukwhitegoods.co.uk/43947…dge-air-sensor
My wiring diagram shows an “ff evaporator sensor” and a “defrost sensor”. Both NTC.
Am I right in assuming the evap sensor 4394720185 with shrink wrap on the sensor is the sensor that goes on the evap assembly. – if so this is the defrost sensor on my wiring diagram?
conversely the “fridge air sensor” 4394720285 which is plain white, is the one which gets buried in the back of the cool panel of the fridge, under all the insulation? – this is (CONFUSINGLY) my evap sensor on the wiring diagram??? going into KN3?
Really hoping someone can set me right before I start mucking about.
Both sensors are the same. But what is the problem? My advice would be to measure the resistance across the sensors at the wiring harness and see if you can bring them roughly back to spec with a simple 1/4w resistor cut in to the wiring, either in series or parallel as appropriate.
I have experienced similar issues on a different Beko Fridge / Freezer. On my model concerned, there are THREE sensors on it. The sensor buried into the rear of the unit, below, and to the right of the control board, is a control sensor. Beko’s name for it, I’m not too sure. It compares the temperature measured, with the set temperature on the control within the fridge. If they differ, the compressor will fire up, increasing the refrigeration. There are TWO further sensors within the Freezer on my model. I think that these are an evaporator sensor, and a defrost sensor. The defrost sensor tells the control board when to activate a defrost cycle. ( When it gets too frosted up ) The other one monitors the temperature of the refrigerant within the freezer, also controlling the compressor / freezer fan. ( I think ). The sensors are thermistors. they Should have a resistance across the when measured with a meter. They ARE NTC, or negative temperature coefficient types, which means their output in millivolts INCREASES, as the temperature DECREASES. It is NOT a good idea to place additional resistors into the circuit, to compensate for a low or wrong reading on a thermistor. This will merely cause the thermistor to send an incorrect reading to the control board ( or none at all ). The Fridge / Freezer WILL NOT operate correctly. Beko have offered little or no help on the matter. I’d be interested to know where you obtained the drawing of you model from please, if you can offer some help.
[USER=”57345″]Bekoranger[/USER] sure, I got the wiring diagram from beko website in the parts and accessories section, they don’t appear to list the diagram for every model but most of them. I
just fixed my issue actually, whicht was the fridges sensor – I was just baffled that the two sensors I bought had different names but essentially they’re identical thermistors bar packaging and varying fitting bits and bobs.Three sensors is mad lol.
Thank – you LanciaMad. Three sensors isn’t really mad. They all serve a purpose. Look at cars, they have even more sensors on them. Although it is more to go wrong, it makes the product ( either car or Fridge / Freezer far more efficient and controllable. Although a wiring diagram probably wouldn’t help me too much, it certainly be of benefit.
