Re: Beko CDA648FS/1 Frost Free Fridge Freezer-Fridge is Froz
Hi bluerobin,
Just follow my instructions dated 26 August 2015 – you’ll find the defective thermistor right there. Switch the fridge/freezer off. Use a wooden spatula to take out the foam insulation and have a new thermistor ready to connect up. What have you got to lose? The unit is broken anyway.
Sorry, don’t know how to upload pictures – you don’t really need them anyway. Just a tape measure and X marks the spot. Save yourself £300.

Just an update to my entry on Wed, the new thermistor fixed the problem.
The new thermistor and the old one both read about 10.2K Ohms at room temperature (give them time to get to the same temperature), so I’m not really sure why the new thermistor works and the old one doesn’t. Note that the fridge initially froze then slowly thawed to normal after fitting the new part.
Also, please note that the new thermistor from eBay had a black plastic sleeve over it. I had to cut this away in order for it to fit into the slot at the back of the fridge compartment. Cut away only enough to allow it to fit and don’t cut near the wires or there’s a risk of damaging them.Re: Beko CDA648FS/1 Frost Free Fridge Freezer-Fridge is Froz
Hello everyone. I too had the same problem with my fridge section freezing despite having the dial on 1. The part you are looking for is a thermistor (changes its resistance with temperature), which is inserted into a slot attached to the back of the fridge compartment. Turn the unit round and measure 22cm down from the top and halfway across the back, Cut away the corrugated plastic back cover and dig down about 5cm until you find the sensor which is about 5cm long and inserted into a sleeve which is attached to the metal back of the fridge section. I made quite a large hole in order to find it. I used a wooden spatula to do the actual cutting away in order not to damage anything. I dug out several cupfuls of foam. The 2 wires were contained in a blue plastic sleeve and it connected to the circuit board located behind a white cover at the top. The original wire colours were grey and orange. You will have to solder the new sensor wires to the old connector as the new one I bought from Ebay (4394720185 for £8.99) had red and blue wires. It doesn’t matter blue to orange or blue to grey as it’s not polarised like a battery. IMPORTANT..Don’t forget to reseal the back with expanding foam else you will get condensation running down the back of your fridge. Nobody has mentioned this vital step. Wickes sells a 300ml expanding foam can for £2.99.
