Understanding the Samsung Dryer tE2 Error
The tE2 error on a Samsung dryer indicates a temperature-sensing problem — typically a fault with the dryer’s secondary temperature sensor or its circuit. When the control board receives an out-of-range signal (open, short or wildly fluctuating resistance) from the thermistor or temperature sensor, the dryer will display tE2 and may stop the cycle or enter a fault mode. This error can cause longer drying times, clothes coming out damp, inconsistent heat, and in some cases can allow overheating if the control board receives bad data and cannot regulate the heater properly. Users may also notice the dryer cutting out mid-cycle, failing to start heating, or displaying other related codes if multiple sensors are affected.
Common Causes
- Faulty thermistor/temperature sensor (open or shorted)
- Broken or damaged wiring harness to the sensor
- Poor or corroded connection at sensor or control board
- Defective main control board (bad sensor input circuit)
- Blocked vent or airflow issues that stress temperature sensors (secondary contributor)
- High-limit thermostat or safety cutout failure causing abnormal temperature readings
- Physical damage from repairs or shipping that disturbed sensor or connectors
Troubleshooting Steps
- Power off and unplug the dryer: always disconnect power before inspecting internal parts.
- Locate the temperature sensors/thermistors: consult your model’s service manual; tE2 often refers to the exhaust or secondary sensor.
- Inspect wiring and connectors: look for burnt insulation, pinched wires, bent pins, or obvious corrosion at both sensor and control board ends.
- Test the thermistor with a multimeter: measure resistance at room temperature and compare to the service manual specification (most NTC thermistors read a specific ohm value at 25°C). A reading of open (OL) or short (near 0 ohms) indicates a bad sensor.
- Check continuity of the harness: verify there is continuity between the sensor plug and the control board connector to rule out a broken wire.
- Swap or temporarily replace the sensor: if you have a known-good replacement or a donor sensor, substitute it to confirm the fault clears.
- Inspect vent and airflow: clean lint buildup and verify the vent path; severe airflow restriction can cause erratic temperature readings and secondary faults.
- Examine the control board: if sensors and wiring test good, look for burned components or connectors on the PCB. A faulty input circuit on the board can cause tE2.
- Reset and test: after repairs, reconnect power, run a short cycle and monitor temperature behavior and whether the tE2 code returns.
- When in doubt, call a certified technician: if tests are inconclusive or the control board appears defective, seek professional diagnosis to avoid safety risk.
Maintenance / Prevention Tips
- Keep the exhaust vent and lint trap clean to maintain proper airflow and reduce sensor stress.
- Inspect the vent hose and exterior vent hood annually for blockages.
- Avoid overloading the dryer; excessive load can cause uneven heating and sensor strain.
- Use recommended dryer cycles and avoid high-heat cycles when not needed.
- Check the power cord and plug for damage each season.
- Periodically inspect sensor wiring and connectors for wear or pest damage.
- Clean inside the cabinet when doing major lint removal to prevent sensor fouling.
- Replace brittle or cracked vent hoses with smooth, code-compliant ducting.
- Use metal ducts instead of plastic or foil flex when possible for better airflow.
- Ensure the dryer sits level to reduce strain on internal components and connectors.
- Have a professional service the dryer every 2-3 years, especially if heavily used.
- Avoid storing heavy items on top of the dryer that can damage the control panel or connectors.
- When replacing parts, use OEM or high-quality compatible sensors and connectors.
- Document any repairs and parts replaced to speed future troubleshooting.
- Allow proper clearance around the dryer for ventilation and service access.
- Check for and correct any repeated power surges or electrical issues in the home.
- Replace the lint filter immediately if damaged to prevent lint bypass and internal contamination.
- Keep the area around the dryer free of combustible materials to reduce fire risk.
- Educate household members on proper loading and lint maintenance habits.
FAQs
Q: Is tE2 dangerous? A: The code itself is a sensor fault indicator and not immediately dangerous, but because it affects temperature regulation it can indirectly increase fire risk or cause overheating if ignored. Treat it seriously and avoid using the dryer until resolved.
Q: Can I clear tE2 by unplugging the dryer? A: A power reset can temporarily clear the code if it was a glitch, but if the underlying sensor or wiring problem remains, the code will likely return. Use a reset only as a first quick step after ensuring safety.
Q: How much does it cost to fix? A: Costs vary by part and labor. Replacing a thermistor is typically low-to-moderate cost, while a control board replacement is more expensive. Expect parts+labor to range widely depending on your region and model.
Q: Can I replace the sensor myself? A: If you’re comfortable with basic appliance disassembly and have the correct replacement sensor and tools, you can, but follow the service manual and disconnect power first. If you’re unsure, call a technician.
Conclusion / Safety Notice
Temperature sensor faults like tE2 should not be ignored. While some users can safely inspect and replace a thermistor or wiring with basic tools and the correct part, sensors and control boards interact with live electrical components and heating elements that present burn and shock hazards. If the fault persists after basic checks or if you find damaged wiring or a suspected control board failure, stop using the dryer and contact a qualified appliance repair technician or Samsung service. Prompt, safe repair protects your appliance, laundry, and home.
If you are comfortable performing the steps above and have the right replacement parts, proceed cautiously; otherwise, arrange professional service to diagnose and correct the tE2 error.
