Re: Samsung Fridge/Freezer RS20CCMS Defrost Issue With Pics

Ive replaced it (the defrost sensor – orig white one with new black one), so i guess i shall have to just wait and see if the problem reoccurrs.

I was wondering if there is a way to bridge the sensor and force the heating element to warm up that way i could confirm there is nothing wrong with
the heating element.

Hi again,

Thanks for all the help so far – I shall purchase a new one from you in due-course.
Before I do – is there anywhere i can see a guide to removal as it seems rivetted on?
Do I have to grind it off and then bolt a new one on or does a new one come with a fixing kit?

Sorry for all the questions – cannot thank you enough so far btw

Hi Bob

Thanks for the reply, one thought I have is that if the heater is testing okay then maybe the circuit is just not getting switched on.
Does the bottom and top heater get switched on separately?

Is there a way i can test the bottom heater – eg bridge a connection to force it to come on?

The bottom heater looks rivetted on – does this mean i have to grind it off, how does the new one fit? bolts??

Sorry for all the questions

Hi Guys

Thanks for all the help so far.

I duly ordered a defrost sensor – but when i received it i got no reading on my multimeter. Turns out my multimeter
is defunct. So after purchasing a new one I can now give corrected readings

Top Plug — Themostatic Fuse 0.00/tone
Middle Plug — Top Heater 141
Bottom Plug — Defrost Sensor 13.0 cold

Bottom Heater — Top Right Plug 430

Is it safe to bypass the thermostat to force the heater to come on?
How can i test the timer circuit? Cannot seem to find it around the back of the unit — is it in the fridge section?
Also notice a mild build of ice forming on the wiring – not dusting but solid water globules (frozed solid drips of water). Evaporator was very slightly coated in frost

Did you check both heaters as 2 heaters on this model main defrost heater on the evaporator and drain heater on the bottom.

The sensor is no 1 on your photo and the sensor is the one on the WTA shop link you have given.

If the main defrost heater is working it defrost but the drain at the bottom blocks with ice if the bottom heater is not working.

No I only checked the bottom heater above the drain, did not see another heater – not sure where that lives (any ideas). The bottom heater
was actually sat in a block of ice when i removed the plastic cover – the evaporation tubes were totally frost/ice free so I presumed that
the either the bottom heater was broken or it was not switching on.

Hi, firstly – thanks for the answers.

@Samuri – I assumed that the heater was ok as it showed continuity on the multimeter

@r600a – Change the “defrost sensor” – would this be ‘No1’ in the images . This gave a reading of ‘1’ at room temperature when tested for resistance.

Would this be the correct part ?
