Samsung Dryer Error Code: tE — What It Means and How to Fix It
The tE error on a Samsung dryer indicates a problem with the dryer’s temperature sensing system — most commonly a fault in the temperature sensor (thermistor) or its related circuitry. When the control board receives an implausible temperature reading (open, short, or out-of-range value), the machine logs the tE code and may stop heating, extend cycle times, or shut down to protect against overheating. Users typically see longer drying cycles, items not drying properly, or no heat at all. In some situations an unchecked temperature-sensing failure can create safety risks (overheating or unreliable automatic shutoff), so addressing this code promptly is important.
Common Causes
- Faulty temperature sensor (thermistor) or sensor assembly
- Broken or corroded wiring / loose connectors between sensor and main control board
- Failed main control board (incorrect signal interpretation)
- Tripped thermal fuse or high-limit thermostat that affects temperature readings
- Blocked vent, lint screen or exhaust duct causing extreme temperatures and erratic sensor behavior
- Moisture or condensation on sensors that leads to shorting or incorrect readings
- Intermittent door switch or drum issues that alter cycle and sensor feedback
Troubleshooting Steps
- Power cycle the dryer: Unplug the dryer or switch off the breaker for 1–2 minutes, then restore power to clear false errors and see if tE returns.
- Check vents and lint: Clean the lint filter, remove lint from the drum, and inspect the exhaust duct for blockages. Restricted airflow can cause heat-related sensor faults.
- Inspect visible wiring and connectors: Unplug the dryer and inspect the wiring harness to the temperature sensor for burned spots, corrosion, or loose connectors. Re-seat connectors firmly.
- Locate and test the thermistor/temperature sensor: Find the sensor (usually near the heater or exhaust). With the dryer unplugged, disconnect the sensor and check for continuity with a multimeter. You should see the resistance change when you warm the sensor slightly (use a hair dryer or warm water on the sensor casing). If resistance is open/shorted or doesn’t change, replace the sensor.
- Check thermal fuse and high-limit thermostat: Test continuity on the thermal fuse and high-limit thermostat. If either is blown/open they can cause protection behavior and erroneous temperature readings.
- Inspect the control board and error history: If sensors and wiring test OK, check the main control board for burned components or blown solder joints. Some models allow viewing error history — consult the service manual for diagnostics mode.
- Perform a harness wiggle test: With the dryer
