1E Freezer sensor error
The Samsung 1E error code means the freezer temperature sensor (thermistor) is sending an invalid reading. This is usually a failed $8-$18 sensor — one of the easiest Samsung fridge repairs you can do yourself.
What Causes This Error
Freezer temperature sensor (thermistor) failed
highThe thermistor that reads freezer temperature has gone open-circuit or short-circuit, sending an out-of-range reading to the main board.
Sensor wiring damaged or disconnected
mediumThe 2-pin connector between the freezer sensor and the main PCB has come loose, or the wire has been pinched by the back panel.
Main control board fault
lowThe ADC (analog-to-digital converter) circuit on the main board that reads the sensor has failed.
How to Fix Error 1E
- 1
Power cycle the refrigerator
Unplug for 5 minutes, then plug back in. If the error clears and the freezer reaches temperature normally, it was a one-time glitch.
- 2
Enter diagnostic mode to read sensor value
On most Samsung models: hold the Power Freeze and Fridge buttons simultaneously for 8-10 seconds. The display will cycle through sensor readings. The freezer sensor should show a temperature (not 'Er' or a wildly wrong number).
- 3
Locate the freezer temperature sensor
Remove the back panel inside the freezer compartment (usually 4-6 Phillips screws). The freezer thermistor is a small capsule clipped to the evaporator coils or mounted on a bracket nearby, connected by a 2-pin wire.
- 4
Test the sensor with a multimeter
Disconnect the sensor and measure resistance. At 0°F (-18°C) it should read approximately 16k-17k ohms. At room temperature (77°F) it reads about 5k ohms. An open circuit (OL) or 0 ohms means it's failed.
Always unplug the refrigerator before disconnecting any sensor. - 5
Check wiring and connector
Inspect the 2-pin connector for corrosion or looseness. Follow the wire back toward the main board looking for pinch points or damage where it passes through the cabinet wall.
- 6
Replace the freezer thermistor
If the sensor tests bad, order Samsung part DA32-10105R or DA32-10109V (varies by model). It clips in place and plugs into the existing connector — a 10-minute repair.
Replacement Parts
If the steps above don't fix it, you may need one of these parts:
Freezer Temperature Sensor (Thermistor)
$8-$18Main Control Board
$80-$250When to Call a Professional
If the sensor and wiring test fine but the error persists, the main control board likely needs replacement
- Main board diagnosis requires checking voltage at the sensor connector pins
- If the board's ADC circuit has failed, a new DA92-00384B or equivalent board is needed
- A technician can read full error history to confirm the failure pattern
