Samsung Range Error Code SE2

SE2 on a Samsung range indicates an open circuit problem in the oven temperature sensor. The control board cannot detect a valid signal from the oven sensor probe, so it shuts down oven operation and displays the code. This is most often caused by a failed sensor probe or a wiring issue between the sensor and the control board.

The oven portion of the range should not be used while SE2 is active because the control board cannot monitor oven temperature, creating a risk of overheating. Surface burners on a gas or electric range may still function depending on the model, but the oven should remain off until the sensor issue is resolved.

Repair costs depend on which component has failed. An oven temperature sensor is typically the least expensive fix, with parts generally ranging from $20 to $60 and labor costs varying by region if a technician is hired. A replacement control board is significantly more expensive, often ranging from $150 to $350 or more for parts alone. Getting a diagnostic appointment with a qualified technician can help confirm the faulty component before purchasing parts.

A reset can clear SE2 if the error was triggered by a temporary voltage spike or software glitch. Press the CLEAR/OFF pad first, then disconnect all power to the range for at least 30 seconds before restoring power. If the code returns when you attempt to use the oven again, a physical component fault is present and needs to be diagnosed and repaired.

Start with the power reset described in the first diagnostic step: press CLEAR/OFF, then disconnect power for at least 30 seconds and reconnect. If the code returns, use a multimeter to test the oven sensor probe for continuity and approximately 1080 ohms of resistance at room temperature. A reading of infinite resistance means the sensor needs replacement. If the sensor tests fine, inspect the wiring harness and connectors for damage or corrosion before considering a control board issue.
