BEKO fridge freezer problem

[billandben]

Hello,

My daughter has a BEKO Model CDA653F fridge/freezer. The top half i.e. the fridge, appears to be freezing continuously and everything goes solid… We’ve tried emptying it all and leaving it for a day with the doors open, hoping that would help but unfortunately it hasn’t…

The thermostat control for the fridge is at the top, inside the light fitting. I’ve removed the lamp cover hoping that would enable me to gain access to the thermostat and/or any electronic pcb’s but I still can’t get at it – I presume I need to remove the entire housing but I’m at a loss to see how.

I’d be grateful for any help. Incidentally I’m a reasonably competent diy’er and have a good array of tools and test equipment, ohm meter etc.

Thank You.

Re: BEKO fridge freezer problem

Hi is there any chance you have the temperature of the fridge set to low?
Other than sorry its the only advice i have as i dont know much about fridge/freezers

Re: BEKO fridge freezer problem

The thermostat in the top is a small potentiometer and there’s a pcb on the back wall at the rear of the appliance.
If the fault is not with these then it’s likely to be a sensor issue and I’m not sure the fridge sensor can be changed

Re: BEKO fridge freezer problem

Thanks for your input.

I’ve replaced the main control board at the rear of the unit and that has not made any difference, the fridge over-cools, milk freezing solid.

Adjusting the thermostat makes no difference. I’ve removed the small pcb inside the dome light fitting and checked the pot and it’s ok. I’ve also checked the wire continuity between the thermostat and the appropriate connector on the main control board at the rear and all is ok. So I could only assume there’s a sensor somwhere which I can’t find so as a last resort I called my local BEKO recommended ‘engineer’.

The engineer quickly informed me that the control board had failed 😮 I explained that I had already changed that, so he then said the small pcb with the thermostat pot had failed and that he would get one 😮 Now as far as I can see there’s nothing else on the pcb that I might have missed so changing that shouldn’t make any difference.

If changing the thermostat pcb DOES cure the fault I’ll be a happy chappy but I’m not holding my breath…

Re: BEKO fridge freezer problem

This will be the fridge evaorrator sensor faulty and it is foamed in so it is not repairable.

“This will be the fridge evaorrator sensor faulty and it is foamed in so it is not repairable”

Now that’s all I need…the unit is only 3 or 4 years old.

Realistically this could be repairable with a bit of ingenuity – anyone out there done this? Presumably the sensor will be a two wire device whose resistance changes with temperature, which will be connected to the main control board at the rear. I presume it could also be a make & break sensor though as the temperature is adjustable I doubt it. I’m assuming it’s not one of those old capillary things… Anyone know which wires on which connector block on the control board it connects to? Surely it’s just a matter of getting a replacement from the freezer compartment to the the board? A copy of the wiring diagram would be helpful.

I may be over-simplifying things here but in over 40 years of electronics I’ve often found that there are ways to get ’round such problems. Never admit defeat – especially as it’s me that will have to pay for the new one !!!

Re: BEKO fridge freezer problem

You have to cut in to the foam insulation to get at the sensor.

The insulation can never be repaired successfully and leads to other problems.

Other manufacturers have tried mods during Warenty cutting in to the insulation to replace sensors without success as it has caused other problems.

Re: BEKO fridge freezer problem

Appreciate you taking time to reply, thanks.

Why is the sensor foamed in I wonder. Have you any idea where it’s physically located? Any electrical component can fail and if it means the whole unit has to be discarded because of the failure strikes me as poor design – or planned obsolescence of course. Maybe BEKO want to sell a replacement fridge/freezer that will last another 3 or 4 years. My daughter’s BEKO washing machine gave problems when it was just out of warranty as well so I suspect she’ll not be buying BEKO again. My old dad always used to say ‘buy cheap, buy twice’ Trouble is this wasn’t particularly cheap…

If I could find a wiring diagram/cct diagram I’m sure I could make this infernal machine work – if only to prove to myself that it was possible.

Thanks again for your patience.

Re: BEKO fridge freezer problem

It is cheaper for manufactures to foam in sensors and as you say built in obsolescence.

A lot of manufactures now foam in sensors even LIEBHERR but LIEBHERR have an access hole for the air sensor in the fridge and now make a mod to fit a fridge evaporator sensor to the models with a foamed in sensor.

On the BEKO the only way is to cut away the foam insulation and this makes it not repairable.

Re: BEKO fridge freezer problem

Well after 3 visits from Beko’s recommended local Service Engineer (different Engineer each visit) its confirmed that the problem is a foamed in sensor. According to the third Engineer the actual sensor may be ok but its probably come away from the point where it was originally glued to, so its not correctly sensing the temperature within the fridge, hence calling for more cooling. This resulting in over cooling.

Now as this unit is less than 4 years old I may have a go at repairing it myself. IF I have any luck I’ll post on here…

Thanks for all your input and help.
