Samsung Refrigerator 5E error code

The sensor that monitors the fridge compartment evaporator during defrost cycles has failed. Defrost cannot run correctly, so ice can build up and block cold airflow in the fridge section.

Also shown as: 5E, 5C

Last updated: October 6, 2026

Quick answer: Samsung refrigerator error code 5E: fridge defrost sensor failure. The most common cause is failed fridge defrost sensor on the evaporator. Try this first — power-cycle the refrigerator. If that does not clear it, defrost the fridge section fully. If the code persists, call a qualified technician.

What causes the 5E error?

  • Failed fridge defrost sensor on the evaporator
  • Sensor separated from its housing near the evaporator coils
  • Loose, cut, or corroded sensor wiring
  • Short circuit in the sensor circuit
  • Sensor reading out of range (above 65 C / 149 F or below -50 C / -58 F)
  • Main control board misreading the sensor

How to fix Samsung 5E — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Power-cycle the refrigerator
    Unplug the fridge for 2 to 5 minutes, then restore power. This clears false codes from power glitches. A 5E that returns immediately means a real sensor or wiring fault.
    Safety warning: Unplug the fridge before touching any wiring.
  2. Defrost the fridge section fully
    Unplug the fridge, move perishables to a cooler, and leave the fridge door open for a few hours with towels down. This melts ice around the evaporator and sensor, which is a common trigger.
    Safety warning: Never chip ice off coils with a sharp tool.
  3. Keep the fridge vents clear
    Food packed against the back wall blocks airflow and ices up the evaporator area. Leave space around the vents so air circulates.
  4. Check the door gaskets
    Leaky gaskets feed constant humidity to the evaporator, overwhelming defrost and icing the sensor. Clean the gaskets and replace any that are torn.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • 5E returns after a power cycle and full defrost
  • Frost rebuilds quickly on the fridge evaporator
  • The defrost sensor, heater, or fuse needs testing or replacement
  • The main control board is suspect

Frequently asked questions

What is the difference between 5E and 2E?

2E is the fridge compartment temperature sensor. 5E is the defrost sensor on the fridge evaporator coils - it monitors defrost cycles, not the air temperature.

My fridge is getting warmer with 5E showing. Why?

Failed defrost lets frost choke the evaporator, so less cold air reaches the fridge compartment even though the system is running.

Where is the fridge defrost sensor?

In the refrigerator compartment behind the Twin Cool cover, near the upper right of the evaporator coils. Accessing it requires panel removal - technician work.
