beko fridge/freezer Model CDA539FW-2

[gjutla]

HI
I am looking for some help on the above model.The problem is that the fridge freezes every thing inside as I am not able to control the temperature via the knob.After reading all the posts in the forum the more likely cause is a sensor which is buried inside by insulation and is near the control board.I am also aware that to gain access the insulation has to be dug up for replacement.But surely there must only be 2 wires from the sensor leading to control pc board and we should be able to check it with a meter.If I am right can anybody let me know the colour of the wires and what resistance to expect on the control pc board
Thanks
Gurcharan

I can’t see any resistances mentioned on the Beko tech documents but it does sound very much like a thermistor problem.

Hi
Thanks for the post.Sorry about mentioning resistor.I think it must be the sortof Thermister or sensor which sends a signal SWITCH OFF (open-circuit) to the control pcb board after reaching a set temperature by us inside the fridge.The control pcb board then switch off the compresser.Obviously it has to be done by 2 wires leading to control pcb board from the sensor.My question is still the same.Which are those 2 wires on the control pcb board?
Thanks and any further help will be appreciated.

No.

The resistance of the sensor is read continuously by the board and the board switches on and off the compressor etc based on that info.

Wrong or invalid resistance and it all goes pear shaped, just as described.

Ok Thanks.Do you know how to replace this sensor or where is it located?
Thanks again

As much detail as you’ll get is on these two articles:

http://www.ukwhitegoods.co.uk/help/fix- … hermistors

https://help.ukwhitegoods.co.uk/support … er-sensors

I believe Dave sends a copy of the bulletin with each sensor, not sure if that’s electronic or not.

Hi again,
I would like to have further help with the above fridge/freezer.I managed to open the back of the freezer compartment and I found 2 control devices.one of them is a thermal fuse and the other is a small cylinder shaped device which I guess is a sensor.But I do not understand if this sensor actually controls the temperature of the fridge which is freezing or if there is another sensor behind the fridge compartment which is not accessable.
Thanks again

I don’t know, I’ve never done one personally.

Seems that it’s detailed out pretty well with photos in that support article though. It is in usual manufacturer speak though in that, they expect the reader to have an understanding of the unit.

On the diagrams they don’t even show those as a spare part, I imagine that the intent was that they should never need to be changed but a lot of manufacturers have found out, that just ain’t so. Due to that though, I can’t even tell you where they are on any particular cabinet, I’d guess you just have to following the wiring to locate them, that’s all I’d do.

HI Kwatt
Fridge is now working after moving about the little cylinder shaped sensor behind the freezer cover.I suspect it is faulty.But according to the DRAWINGS on the website the sensor supplied has only 2 wires and the one fitted has 4 wires .I guess it is a modification but the pics are quite blurry and the colour of the wires cant be seen.Is it possiable to elaborate before I order the part
Thanks

Other than the info given, which is from Beko, not really unless one of the guys has done one and knows any more.
