Samsung RL36EBNS "rd" error

[michi]

I have a Samsung RL36EBNS fridge freezer, when I turn it on it start up and then stops "rd" is displayed on the display. After doing a bit of research I found that it has something to do with either the fan motor or the sensor I have taken the cover off and checked; when the fridge/ freezer powers up the fan starts spinning and the little square blade starts spinning (to me that rules out any motor failures, please correct me if I am wrong), so I think I will need to replace the magnetic position sensor?
If that's the case where can I buy the sensor or does it only come as part of some motor...?


Thank you for your help and advise.

How can I find out which sensor is at fault, as there are a few in there.

Thanks
