Answer to continue safely
Is it safe to keep using?
Maybe.
Can I reset the code?
Yes.
When to stop immediately?
Stop if you notice: Freezer interior temperature rises above 10 F (-12 C) despite the compressor running, Ice buildup is thick enough to prevent the door from closing fully.
Symptoms You May Notice
Heavy frost buildup on rear freezer wall
Thick ice forms on the back panel of the freezer compartment because the automatic defrost cycle is not completing properly.
5E error code on display panel
The digital panel shows 5E or the SmartThings app sends a defrost sensor alert notification.
Freezer temperature gradually rises
As ice blocks the evaporator airflow, the freezer interior warms above the set temperature over days or weeks.
Unusual hissing or dripping sounds
Ice melting partially during incomplete defrost cycles creates intermittent hissing or water dripping noises behind the rear panel.
Possible Causes
Failed defrost thermistor
The thermistor element corrodes or develops an internal break, producing open-circuit readings that the control board interprets as a sensor failure.
Requires ProfessionalDamaged sensor wiring harness
Repeated freeze-thaw cycles cause the wire connections between the sensor and control board to fatigue and break, especially at pass-through points in the freezer wall.
Requires ProfessionalIce encasing the sensor
A previous defrost failure allows ice to completely envelop the sensor, insulating it from accurate coil temperature readings and perpetuating the defrost failure.
DIY PossibleSafe Checks You Can Do
-
1
Perform a manual defrost
Unplug the freezer, remove all food to coolers, and leave the door open for 24 hours. Place towels around the base to catch meltwater. This clears ice that may be affecting the sensor.
Use a fan directed into the freezer to speed up the defrost process — never use a hair dryer or heat gun on the evaporator coils.

2
Inspect for frost patterns
After plugging back in and running for 24 hours, check behind the rear interior panel for uneven frost. Heavy frost on one section of the evaporator suggests the defrost sensor location.
On Samsung Bespoke freezers, the rear panel is held by clips — do not force it, as the evaporator is directly behind it.

3
Monitor temperature after reset
Place a thermometer inside the freezer after the manual defrost. Check every 12 hours for 48 hours. If the temperature holds at 0 F (-18 C) and 5E does not return, the ice was the issue.
Samsung SmartThings app provides real-time temperature graphs that are easier to monitor than a manual thermometer.
Tools required
When to Call a Professional
Contact a qualified technician if:
- 5E returns within days after a complete manual defrost
- The evaporator coil has uneven frost — heavy on one side, bare on the other
- Sensor wiring is visibly damaged or corroded at the connector
