Thank you for this service. We were trying to find a popped breaker yesterday and turned every breaker off and on. Now we are receiving a message on our Samsung Refrigerator LCD screen that states:
Checkpoint: FF Def Sensor
Check the cooling room (Freezing Room)
Prolonged storage may damage foods.
OK (hold for 3 seconds)
So I held the button and the message reappeared today. We are selling out home in 11 days and I want to avoid a costly technician call out. I am not sure if I need to purchase and replace the defrost sensor assembly, or if I need to reset something to get the message to stop coming on the screen? Any help would be most welcome. Thank you.

ANSWER Hello Chris,
You will want to pull the rear wall of the refrigerator section to see if there are any burnt or broken wires to the defrost thermostat or thermistor. If there is then you will need to replace. You can also check resistance to make sure that you have resistance through the thermistor and thermostat. If you do not have resistance and it is reading open then this would be the cause of the failure.
