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 temperature rises above 15 F (-9 C) with food inside, The compressor runs non-stop for more than 24 hours without cycling off.
Symptoms You May Notice
Freezer runs constantly without cycling off
The compressor operates non-stop because the control board has no valid temperature reading to determine when to shut off.
1E error code on display panel
The control panel displays 1E and may flash or beep to alert the user to the sensor failure.
Food partially thaws or overcools
Without accurate temperature monitoring, the freezer may alternate between being too warm and too cold, causing freezer burn or soft food.
Temperature display shows dashes or unusual reading
The digital temperature readout may show dashes, a blank, or a wildly inaccurate number instead of the actual temperature.
Possible Causes
Failed thermistor
The temperature-sensing bead develops an open or short circuit from thermal cycling fatigue, sending invalid resistance values to the control board.
Requires ProfessionalLoose wiring connector at PCB
The multi-pin connector where the sensor wire plugs into the main control board can work loose from vibration, intermittently breaking the signal.
Requires ProfessionalFatigued sensor wire in hinge area
On Samsung Convertible freezers, the sensor wire passes through a flexible hinge zone where repeated door opening can break individual conductors inside the insulation.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle the freezer
Unplug the freezer for five minutes, then plug it back in. Monitor the display for 1E — if it clears and the temperature reads normally, a temporary glitch was the cause.
Place a cup of water with a coin on top in the freezer. If the coin sinks into the ice while you are away, the freezer lost cooling at some point.

2
Check sensor area for obstructions
Locate the temperature sensor on the upper rear wall of the freezer (usually behind a small clip-on cover). Ensure no food is pressed against it and no ice has formed over it.
The sensor looks like a small dark bead on a thin wire — do not pull or bend it, as the thermistor element is fragile.
When to Call a Professional
Contact a qualified technician if:
- 1E returns immediately after every power cycle
- Temperature display shows dashes or a fixed incorrect number that does not change
- The compressor cycles erratically — rapid on-off switching every few minutes
