Samsung Range Error Code SE3

SE3 on a Samsung range indicates a shorted oven sensor problem. The oven temperature sensor or its wiring has developed a short circuit, causing the resistance signal sent to the control board to fall outside the acceptable range. The oven shuts down to prevent unsafe operation until the fault is resolved.

It is not recommended to use the oven while SE3 is active. A shorted temperature sensor means the control board cannot accurately monitor oven temperature, which could result in overheating or unpredictable oven behavior. The oven should remain out of service until the sensor circuit is diagnosed and repaired. The stovetop surface burners may still function normally depending on the range model.

Repair costs vary depending on the root cause. A replacement oven temperature sensor probe typically costs between $15 and $60 for the part alone. If professional labor is required, total repair costs including parts and service can range from $100 to $300 or more depending on your location and the technician. Control board replacement, if needed, is the most expensive scenario and can push costs higher.

A reset can clear SE3 if the fault was caused by a temporary electrical glitch. Press the CLEAR/OFF pad first, then restart the oven. If the code returns, disconnect all power to the range for at least 30 seconds before reconnecting. If SE3 comes back after a full power reset, the sensor or wiring requires physical inspection and likely replacement.

Start by pressing CLEAR/OFF and restarting the oven, then perform a 30-second full power disconnect if the code persists. If the error returns, the next step is to inspect the oven temperature sensor probe for visible damage and test its resistance with a multimeter. Also check the wiring harness between the sensor and the control board for damaged insulation or corroded connectors. If the sensor resistance is out of specification, replacing the probe is the most common repair.
