Samsung Refrigerator Error Code 23E — Condenser Sensor Error
What this means
The 23E error code indicates the condenser temperature sensor (thermistor) is malfunctioning. This sensor monitors the temperature of the condenser coils at the back or bottom of the refrigerator and helps the control board regulate compressor operation. A faulty sensor can cause the compressor to run too long, not run at all, or cycle erratically.
Alternate codes: 23C
Step-by-step fix
4 stepsPower cycle the refrigerator
Unplug for 60 seconds, then restore power. If the code clears and does not return, monitor the unit for 24 hours.
Note the freezer and fridge temperatures before and after the reset to see if cooling behavior improves.
Locate the condenser sensor
Pull the refrigerator away from the wall and remove the rear lower access panel. The condenser sensor is a small thermistor clipped to the condenser coil tubing or mounted near the condenser.
Clean the condenser coils while you have access — dirty coils can affect sensor readings indirectly.
Test the condenser sensor
Unplug the refrigerator. Disconnect the sensor wire connector. Measure resistance with a multimeter at room temperature — Samsung thermistors typically read around 5 kOhms at 77°F (25°C). An OL or extremely low reading means the sensor is faulty.
Compare your reading to the resistance chart in the service manual for your specific model number.
Replace the condenser sensor
Unclip the faulty sensor from the condenser tubing. Install the replacement sensor in the same location and route the wire the same way. Reconnect the harness and reassemble.
Use a cable tie to secure the new sensor firmly to the condenser tube so it reads temperature accurately.
When to call a professional
If the sensor tests within spec but the error persists, the main control board input circuit may be damaged. A technician should perform board-level diagnosis.
