Re: Help with Samsung Fridge PCB problem
Thats great, my working thermistor is spot on, 24.5°C @ 5.667K-Ohms. Fantastic little chart there! worth printout out and sticking on the back of the fridge for future trouble solving!
The ‘dead’ one is showing 0.7K at what is roughly the same temp. Will try and find a replacement locally 🙂
Re: Help with Samsung Fridge PCB problem
That great advice thanks, do you know what the Ohm readings of a brand new fully working thermistor should be? Presume around 6K is close enough!
Anything to rig up at home to test the rest of the circuit is ok?Re: Help with Samsung Fridge PCB problem
This is the half of the screen that lights up, the other half is blank, under normal use only a few of the green segments should light up.

Reading around and doing some checks it looks like a thermistor problem, and the screen lighting up on different sides elates to me swapping the two thermistor inputs on the PCB. One measures 400-Ohms, the other 6K-Ohms, if I could get a big variable resistor I could maybe check it before taking the thing to pieces to get to the faulty part 🙂
R600, hopefully these thermistors breaking is reasonably (however annoying they are!) common, and you have some quick checks I can carry out?
Re: Help with Samsung Fridge PCB problem
Allow me to come back with a photo tomorrow for you.
It’d be great for you to give it a once over 🙂Re: Help with Samsung Fridge PCB problem
Thank you very much for the help there.
It’s not a US/UK spec fridge, it’s an old Korean style chest freezer (2 compartments) only sold in Korea, the display isn’t in English, it’s not an error code as such, more of a 7seg type LCD that has sections that light up (I forget there real name!) So not sounding rude but a photo wouldn’t help.So might just give this up as a bad job! Going to see if the compressor will run when connected up directly though, as there is a slim hope after that!
I guess I was searching for ‘common’ items to fail on 10 year old fridge control boards, and possibly samsung specific errors 🙂
Cheers.
