If your Samsung electric range isn’t heating up correctly or maintaining the proper temperature, the oven sensor might be at fault. The oven sensor monitors the internal temperature and communicates with the control board to adjust the heating elements.
A faulty sensor can result in inaccurate temperature readings, uneven cooking, and other baking issues. Here, we’ll guide you through testing the oven sensor and, if needed, replacing it to get your oven functioning properly again.
Common Signs of a Faulty Oven Sensor
Before jumping into testing or replacing the oven sensor, it’s helpful to recognize some common signs of a faulty sensor. Understanding these symptoms can confirm if the sensor might be the issue rather than another component. Here are some indicators that your Samsung oven sensor may need attention:
- Inaccurate Temperatures: If you notice your food is consistently undercooked or overcooked, despite setting the correct temperature, it could be due to inaccurate readings from a faulty sensor.
- Erratic Temperature Changes: A sensor that is failing may struggle to maintain a stable temperature, causing sudden temperature fluctuations within the oven that affect cooking times and results.
- Error Codes: Modern Samsung ranges often display error codes on the control panel when a component is malfunctioning. Look for codes like SE, OE, or other temperature-related error codes that could indicate a sensor issue.
- Longer Preheat Times: If your oven takes noticeably longer to reach the set temperature, the sensor might not be properly communicating with the control board, slowing down the heating process.
- Burnt or Unevenly Cooked Food: A faulty sensor can lead to hot or cold spots, causing uneven cooking. This may leave some parts of the dish burnt while others are undercooked.
If you’re experiencing any of these issues, testing the sensor and potentially replacing it could help restore your oven’s performance.
Safety Precautions
When working with any appliance, safety is paramount. Follow these tips to minimize the risk of injury:
- Power Off the Appliance: Unplug the appliance or switch off the circuit breaker before beginning any maintenance or replacement work to avoid electric shock.
- Wear Insulated Gloves: Protect your hands from sharp metal parts, pinching hazards, and debris by wearing insulated gloves.
- Work Carefully and Take Your Time: Avoid rushing through the process, which can lead to accidents.
- Ensure Good Lighting: Work in a well-lit area to see and access interior parts clearly.
- Clear Your Workspace: Remove clutter and keep children and pets away from the work area.
- Dry Hands and Workspace: Never handle internal parts with wet hands, and make sure the work area is dry.
- Check the User Manual: Refer to the manual for specific installation or safety instructions for your model.
- Handle Parts Gently: Avoid using excessive force, which can damage the appliance or cause injury.
- Wear Safety Glasses: Protect your eyes from dust, debris, and chemicals if you’re working with them.
- Allow Cooling Time: If the oven has been used recently, let it cool completely before working on it.
- Document Connections: Take photos or notes of wiring terminals and connections before disconnecting them for easier reassembly.
- Avoid Direct Contact with Wires: When handling wires, use non-conductive tools or insulated gloves to reduce the risk of shock.
Tools and Materials Needed

How to Troubleshoot and Replace an Oven Sensor
Access the Oven Sensor
- Unplug the range or turn off the breaker to disconnect the power supply.
- Slide the range out from the wall to access the back.
- Use a screwdriver to remove the rear lower cover on the back of the range to expose the oven sensor.
Test the Oven Sensor
- Locate the oven sensor on the right side of the back of the range.
- Disconnect the harness attached to the sensor.
- Set your multimeter to measure resistance in Ohms.
- Place one multimeter lead on one terminal of the sensor and the other lead on the second terminal.
- Check the reading. It should be approximately 1080 ohms at room temperature.
- If the reading is far from 1080 ohms, the sensor is faulty and needs to be replaced.
Replace the Oven Sensor
- Unplug the range or ensure the power is turned off before removing the sensor.
- Disconnect the sensor wires at the back of the range.
- Use a screwdriver to remove the two screws securing the sensor in place.
- Gently slide the sensor out of its position.
- Slide the new oven sensor into the same position as the old one.
- Reinstall the screws to secure the new sensor in place.
- Reconnect the wiring harness to the sensor.
- Reattach the rear cover of the range.
Test the New Sensor
- Plug the range back in or turn the breaker back on.
- Test the oven to ensure the new sensor is working correctly.
With these steps, fixing your Samsung oven’s heating issues becomes a manageable DIY task. Identifying the signs of a faulty sensor and following the replacement process can help you restore your oven’s functionality without the stress of costly repairs.
Just remember to take safety precautions and go through each step carefully. Once you’re done, you’ll be back to baking your favorite dishes at the perfect temperature.
