Hi Guys,
We have an old Samsung RS21dpsm (S/N 525542bp400442j) and it has a cooling issue.
I thought it was the usual Defrost Heater Sensor Thermistor Thermal Fuse so swapped that, still not cooling.
When doing the self diagnostics, it comes up with error 12, C-FAN ERROR (COMP-FAN) so replaced the compressor cooling fan and still the same issue.
We then called NAC (National Appliance Repairs) who said it was the main board which had an issue so that was replaced and still the same issue.
I got hold of the manual recently to get more info on the fault and it says the following:
C-Fan motor operation failure; feedback
signal line contact failure, motor’s electric
wire missing; and so on.Indicate Error if the F and G signals generated by the
FAN-motor operation are not inputHas anyone had the same issue and fixed it?
It does cool down when you switch it off and on but does not keep the temp down.
Thanks in advance
Sunil
Hi Sunil, I’m having a similar issue with a similar RS21. It’s a different fan, but they all work the same way. I’ve replaced the fan motor as well as the main board. I’ve posted my findings to far. Did you every find an answer?

Mikenot as yet, i did notice a burn mark in the frezzer so will investigate that bit again some point next week. ill keep you posted
Have sorted mine – first replacement fan motor (eBay, seller said was a match) was not compatible with my mainboard, second replacement (OEM, matching part no) works fine. Looks like pre- and post-2006 fan motors are different / not compatible, as is the case with the main boards. From your serial no, looks like yours is a post-2006 so may be worth checking the replacement fan you got was an exact match. It’s all a bit of a mess – the three fans in this fridge have three different part numbers on the diagrams, but when you look closer the two in the fridge and freezer appear to be identical. The compressor fan motor looks the same but has a different spec. Pfft.

can you let know where you got your fans? and which ones? sure the comp fan was different now you say it.. thanks
The first replacement (didn’t work) came from an eBay seller so probs not very useful! Although I think an ebay part where the big number stencilled on the motor was a match would stand a better chance. My original was “7”, replacement was “12”, but the seller listing said they were compatible. My fridge is one of the old ones and the only cheap “7” motors I could find were in Australia or China!
The second motor – the one that worked – was an exact match for the original and came from from https://www.samsungspares.co.uk/. £60 versus £20 for the ebay one, but cheap / not working isn’t good value! If your replacement motor looked the same as the original but had a different part number / big number stencilled on motor it could explain it not fixing the problem and the right part may.
