Samsung Refrigerator 5E code: Fridge defrost sensor error
The sensor that watches the fresh-food evaporator during defrost is giving a bad reading. Frost can build up and cooling can suffer.
Most common causes
- Failed fridge defrost sensor (thermistor)
- Loose or damaged sensor wiring
- Control board not reading the sensor
What you can safely check yourself
- Note the code before doing anything; Samsung asks owners not to clear codes, so the technician can see it.
- Keep doors closed as much as possible and check that food is staying cold.
Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.
