BEKO fridge freezer CDA653FS/1

[franco]

Hi All i have a BEKO fridge freezer cda653fs/1 and the fridge compartment back wall is getting covered with ice and overall the fruidge is just too cold!!!!
I have tried defrosting for 48 hrs but this has made no difference. I have taken out the thermostat board in the fridge compartment and tested the potentiometer with multimeter and it reads from 1.5Kohms to approx 4K ohms so i assume this is ok? Also have tried to locate the sensor thermistors built into the rear of the fridge by cutting out the insulation .Unfortunately the wires for the thermistors appear to disappear into the top of the fridge .Do i have to remove the top of the fridge and the fridge door to access these sensors? .If i could get them out i can test them and order new ones to replace them? It appears that they are not built for easy replacement and access . If anyone can give me some advice i would be truly grateful . I am adept at using multimeter and general repairs so can undertake any suggestions .Many thanks …Franc

This sounds more like a system fault (lack of gas or weak compressor) in this case the compressor may feel particularly hot due to excessive running. The fridge sensor is not designed for replacement on this model.

It’s a common fault the fridge sensor will be the fault.

The trouble is the sensor is foamed in and you have to cut open the insulation on the back of the fridge.

Once you have compromised the insulation you never can insulate it to the same standard as it was made and it only leads to further problems.

Hi All have managed to locate the sensor and remove it for testing with multimeter. It reads from 1.5 Kohms to 22 Kohms in fresh air and cup of hot water. I must admit that I feel if it was faulty it wouldn’t change resistance in this manner.Don’t know what the correct reading should be but at least it’s varying.Do any of u guys know the answer? Or should I just replace anyway?

That’s what it should read as I said earlier the system is at fault.

OK thanks captaincaveman .Jus cant get my head round the fact that its low on gas but fridge is getting too cold? Seems somehow inconsistent imho .How do i get round a system fault unfortunately i dont have equipment to regass it

OK i have now managed to replace the sensor in the rear of the fridge section albeit having been told by official BEKO spares that it is not replaceable ? I had to cut out the insulation and solder the new thermistor in situ then re insulate and seal the sensor back in .The new sensor is not a direct replacement and the resistance value is slightly different to the original but it is now working fine.It appears that BEKO deem this part as not replaceable which is a pity cos its now working fine and only cost me £15 to buy online .Thanks for all ur advice

Hi Franco, well done on resolving.

I am having the same issue as yourself and looking to resolve.

You wouldn’t by any chance happen to remember the part number you used for the sensor?

I can locate the Brown/Black sensor wires, although some replacement sensors tend to have Red/Black wires so really just hoping to use the correct sensor.

Many thanks

The sensor is a common fault on this model glad you were able to repair.
A system fault e.g. Low on Gas or poor compressor can cause a fridge to get too cold but the wet wall would only freeze near the top and not even across the back.
This is because it would not get cold enough near the sensor or stat to turn off the compressor.

Hope this helps you understand how a fridge can get too cold with a system fault.
