Are u still there
Yes, sorry think we got disconnected somehow
sorry to hear about the problem with refrigerator, have you already tried to leave it unplugged minutes/hours to check if this makes any difference ?
Yes tried that, freezer shows a temp of -3 and not going down, fridge is going up slowly now at +7.
Kevin you still there
Sorry I am have issues here with my router
The problem seems to be with the temperature sensor that is bad and will need replacement
a new defrost sensor will cost around £15
this is a common issue with Samsun RS21 models
as yours is RS20 you can just call in samsung and check with them if they can repair this under warranty
