The evaporator coil in our refrigerator has frozen so the fridge won't maintain a cool temp. Research indicates it may be a bad defrost sensor. Does that sound right? If so, do instructions exist to replace that in model RS27FDBTNSR. A video would be helpful.
I have found videos for other models but they are a totally different design from this 48" wide side by side.
There is no service tech in my area so I'm on my own to fix this.
