I have a samsung RS21 with 2 faults the fridge has the usual fault of ice build up jamming the fan, i know about a mod to cure this the se4cond fault is the freezer is showing 11 degrees but is actualy around -5 the evaporator is freezing correctlty but the freezer fan does not run, when i switched it of fand then again teh fan would run for a couple of seconds then stop and repeated this a few times until it stopped, i was wondering if there might be a thermistor/sensor at fault similar to the Hotpoint mistral fridge freezers, cheers JJ
