Re: Samsung RS21DCSV
Inside the fridge behind the vegetable draws is the water precooler for the water dispenser.
This will be frozen and you will need to defrost it.
This is the first sign the insulation on the panel behind the cooler is breaking down and you will need a new panel.

Re: Samsung RS21DCSV
Hi Posh
If the water tank is frozen then you will need to replace the rear panel,possibly the defrost sensor and hopefully the water tank doesn’t split when its defrosting.
If the evaperator is full of ice / snow when you take the cover off then you might have to replace the heater and or thermal fuse also.All of the parts can be replaced.We also have them in stock also.

Re: Samsung RS21DCSV
Sorry to sort of hijack this post, but this happened to my French bought RS55XDNS some four years ago and I purchased the complete repair kit and effected a successful repair.
Sadly I am having further problems which may be related..
I noticed the fan making noises (as though it is just hitting an ice build up) which stops when I open the door. The water supply is till functioning so not yet frozen. Suspecting potential problems I have turned off the power supply for a couple of minutes to establish results. Before switching off the temps were Freezer -18C and Fridge +4C…..switch off then on readings Freezer -13C and Fridge +13CThe complete kit was installed just over 4 years ago so suspect that I may only need one or two parts replacing. Bryan – I would appreciate your wisdom and input to keep this fabulous piece of kit functioning as it should.
Needless to say Samsung UK offer no assistance apart from giving me Samsung France number as it was bought in France!!! – Now back in the UK.
Re: Samsung RS21DCSV
HI
Dependent on what kit you fitted previously depends on what parts you will need. But You will need to test the heater, thermal fuse, defrost sensor( personally I would change whatever) Also during a modification period there was an extra fuse board fitted next to the main pub at the rear.That also needs to be checked.

Re: Samsung RS21DCSV
Hope it’s ok to jump in here, having a nightmare with my mum’s RS21DCSV which we have taken ownership of. Up until that point, the fridge has worked flawlessly which is what’s baffling me. Between moving sites, it has taken on problems which are mostly what others have experienced. The only thing I did was to clean out behind the back cover because it was absolutely filthy:
After waiting 48 hours, I plugged it in and our first problem occurred, it tripped the house electrics after several hours of operation. Leaving it unplugged for 2 hours was the only way to get it to not trip. I stumbled upon the fix for this by turning off the ice cube making function. Bizarrely, that function now works fine and the fridge no longer trips however the water feed stopped working with the water tank frozen.
The second problem is the display stating an incorrect temp for the fridge. It was showing 14c which when you open the door, clearly is much colder than 14c. After purchasing a standalone temp gauge, I confirmed I was right and that the fridge was colder, much colder. In fact -7c was the lowest temp it hit over 24 hours.
This problem then morphed into the fridge getting incredibly hot at the top, 18c. which the bottom was still really cold, just above freezing although this was occasionally. The majority of the time, the fridge is just too cold 0.1c with much colder in the lower compartments and slightly higher on the top shelves.
Things I have done:
Taken the front panel off to look inside and check continuity checks on the sensors (note I’m not expert on this and have only gone by Youtube), all sensors come back with 1300 or thereabouts.
Still thinking it could be a sensor faulty, I have purchased a “SAMSUNG RS21 Fridge Freezer DEFROST SENSOR DA3200006W” but have not seen any change in the above.
Finally I am now starting to see the heater element freeze over. This wasn’t happening at first but has now started.
Have I been unlucky with timing and this is all a coincidence, or could something have happened whilst the unit was being transported to our house? I don’t want to shell out over £100 for the repair kit to find that wasn’t the cause of my woes. Any advice welcome.
Re: Samsung RS21DCSV
Any reason why that would fail between transit though? Or whether my cleaning in the back of the unit caused anything untoward?
Can I just replace the Main Evaporator Defrost Heater or do you advise changing the sensor, thermal fuse and cover too? I’d rather go down the cheaper route but if you think it’s essential I change out the other parts too, then I will.
Thanks a lot for your help.
Re: Samsung RS21DCSV
If you want the cheapest route then you can change just the heater.
As it runs for awhile before tripping this points to a defrost problem and as it is now frosting over then it shows it is a defrost fault.
Water has most likely entered the defrost heater when it was turned off for transporting so it has shorted out the heater.

Re: Samsung RS21DCSV
Brilliant thank you. Will order the heater and report back after.

Thats the part?
Re: Samsung RS21DCSV
Yes that’s the part.
When you fit it make sure the thermal fuse does not touch the heater.
The thermal fuse is the one with the black & red wires and is wrapped in white foam.
The thermal fuse fits on the right near the bottom between the evaporator coils and has a small gap from the heater, but if it touches the heater you risk blowing the fuse and the heater / Defrost will not work if the fuse blows.

Re: Samsung RS21DCSV
New defrost heater in, nothing has changed 🙁
Temp display seemingly random and yet fridge constantly cooling down.
I took a photo of the old one I replaced just in case you spot anything odd:
If you look at the next pic, I noticed the foam was sat above the tip of the thermal trip, is the right location or should it be down covering the tip?
Other than that, any other suggestion? Fridge currently says 25c, inside thermometer says 7c and still cooling down same as before. Give it an hour and I’ll be back in the sub zero range 🙁
Re: Samsung RS21DCSV
Is the photo before you replaced the heater as this photo shows the old defrost heater.
If you took off the light panel at the top did you plug the air sensor back in ok.
Check the fan in the fridge is working. You can check this buy pressing and holding the light switch.
The fans have a delay it takes thirty to sixty seconds for the fans to cut in and as the insulation on the cover at the bottom does not look in that good a condition the fan may be jammed with ice.
