28E
Samsung Refrigerator
Severity: ModerateWhat Does This Error Mean?
The 28E error on a Samsung refrigerator means the ice room defrost sensor has detected an abnormal temperature reading — or has stopped responding entirely. This sensor monitors the temperature in the ice maker compartment during defrost cycles. Without it working, ice can build up and block the ice maker.
Affected Models
- RF23M8070SR
- RF28R7351SR
- RF27T5241SR
- RF28K9380SG
- Samsung models with ice room compartment
Common Causes
- Ice room defrost sensor (thermistor) has failed
- Heavy ice buildup coating the sensor probe
- Wiring from the sensor to the control board is loose or broken
- Ice room defrost heater has failed, leading to ice buildup that damages the sensor
- Control board issue causing false or no sensor reading
How to Fix It
-
Turn off the ice maker and remove the ice bin from the freezer.
You need to clear out the ice maker area before defrosting it.
-
Unplug the refrigerator and leave the freezer door open for 24–48 hours.
This melts any ice that may be covering or blocking the defrost sensor probe in the ice room.
-
Once defrosted, carefully inspect the small sensor probe in the ice maker area.
Check that the wiring connector is firmly attached. Look for any signs of damage or corrosion on the connector pins.
-
Dry the ice room area thoroughly before plugging the refrigerator back in.
Leftover moisture will refreeze quickly and can cause the sensor to fail again.
-
Plug in, allow 2 hours for temperatures to stabilize, then check for the error.
If 28E persists after a full defrost, the sensor or defrost heater in the ice room needs professional replacement.
When to Call a Professional
If a manual defrost does not clear the 28E error, the sensor or heater needs testing with a multimeter. Accessing the ice room sensors requires disassembly of the freezer or ice maker compartment. Expect repair costs of $120–$230.
Frequently Asked Questions
Is 28E a common error on Samsung refrigerators?
Yes — Samsung French door models with dedicated ice maker compartments are known to develop ice buildup issues. The 28E error is one of several ice room sensor codes that result from this problem. A manual defrost fixes most cases.
My Samsung fridge keeps getting ice room errors every few weeks — what is wrong?
Repeated ice room errors usually mean the automatic defrost system for that compartment is not working. The defrost heater, defrost thermostat, or defrost sensor for the ice room has likely failed. A technician should replace the faulty component to stop the cycle from repeating.
Can I use the refrigerator normally during a 28E error?
The main fridge and freezer sections continue working normally. Only the ice maker will be affected. Address the error within a few days to prevent additional ice buildup from spreading to the freezer fan area.
