1E
Samsung Refrigerator
Severity: ModerateWhat Does This Error Mean?
The 1E error means the freezer temperature sensor in your Samsung refrigerator is malfunctioning. The sensor cannot accurately measure how cold the freezer is. This can cause the freezer to get too cold or not cold enough.
Affected Models
- RF28R7351SR
- RF23M8070SR
- RF263BEAESR
- Most Samsung French door and side-by-side refrigerators
Common Causes
- Faulty freezer temperature sensor (thermistor) giving wrong readings
- Loose or corroded wiring connection at the sensor plug
- Ice or frost buildup on the sensor blocking accurate readings
- Power surge that damaged the sensor circuit
- Main control board not processing the sensor signal correctly
How to Fix It
-
Unplug the refrigerator from the wall outlet for 5 minutes.
This performs a hard reset and clears temporary sensor errors.
-
Plug it back in and check if the error clears from the display.
Wait a few minutes for the display to fully initialize.
-
Check the freezer temperature on the display panel.
It should read around 0°F (-18°C). A very wrong reading confirms a sensor issue.
-
If the error returns, unplug for 8 hours and let the freezer defrost.
Ice on the sensor can cause false readings. Defrosting may fix it.
-
If the error persists after defrosting and resetting, call a technician.
The sensor itself is a small, inexpensive part but requires proper diagnosis.
When to Call a Professional
If resetting does not clear the error, the freezer sensor likely needs replacement. Contact Samsung support or a licensed appliance technician. Expect repair costs of $100–$200 for a sensor replacement. Do not wait too long — incorrect temperatures can spoil food.
Frequently Asked Questions
Is my food safe with the 1E error?
It depends on how the freezer temperature is affected. Check if the freezer still feels cold inside. If food is still frozen solid, you have time to get the repair done. If food is starting to thaw, move it to a cooler immediately.
What is a thermistor in a Samsung refrigerator?
A thermistor is a small electronic temperature sensor. It measures the temperature and sends the reading to the control board. The control board then decides when to run the compressor and fans. Think of it as a thermometer that the fridge reads automatically.
How much does a Samsung fridge freezer sensor cost to replace?
The sensor part itself is very affordable — usually $10–$30. Labor to diagnose and install it is typically $80–$150. Total repair cost is usually $100–$200. This is one of the cheaper refrigerator repairs.
