What this code means
The tE or TE error code on a Samsung dryer indicates a temperature-sensing fault. The dryer is detecting that the temperature reading is out of the expected range, so it cannot regulate heat safely or continue the cycle normally. The control logic stops or inhibits heating to protect the appliance.
This code is most often tied to a thermistor (temperature sensor) problem, but it can also be triggered by an overheat or restricted-airflow condition, wiring faults, or less commonly a control board issue. The dryer is not reading cabinet or exhaust temperature correctly during operation.
Before You Replace Anything
Many people replace the control board first. Check the thermistor resistance with a multimeter and inspect the vent system for blockages before replacing any electronics.
Common Causes
- Failed thermistor or temperature sensor The sensor is open, shorted, or reading out of range and cannot report accurate temperature to the control board.
- Restricted venting or poor airflow Lint buildup, crushed flex duct, long vent runs, or a blocked exterior hood can overheat the dryer and trigger the temperature fault.
- High-limit thermostat or safety circuit issue If the dryer overheats or a safety device opens, the control can report a temperature fault.
- Wiring or connector defects Loose, damaged, frayed, or heat-damaged harness connections in the temperature-sensing circuit cause faulty readings.
- Control board fault Less common, but possible if the sensor and wiring test good and the board has failed input circuitry.
Step-by-Step Fix
- Reset power by unplugging the dryer or switching the breaker off, waiting a few minutes, then plugging it back in to see if the fault clears.
- Check airflow first by inspecting and cleaning the lint screen, vent hose, exhaust duct, and outside hood, and look for crushed or sagging ducting.
- Run a vent-disconnected test if practical and safe by removing the vent hose and running a short cycle to see if the code clears, pointing to a downstream restriction.
- Locate and test the thermistor by unplugging the connector and checking the sensor with a multimeter for out-of-range resistance, open circuit, or short.
- Inspect the high-limit thermostat and safety devices for continuity and signs of overheating, and check the heater circuit for damage if present.
- Inspect all wiring and connectors between the thermistor, heater and safety devices, and main control board for loose pins, corrosion, burned terminals, or heat damage.
- Replace the failed part (thermistor, high-limit thermostat, wiring, or control board), then retest the dryer through a full heat cycle and confirm the code does not return.
Parts Often Needed
| Part | Notes |
|---|---|
| Samsung dryer thermistor or temperature sensor | Amazon | Match the part number to your dryer model. The primary suspect for this code. |
| High-limit thermostat or thermal cutoff fuse | Amazon | Check if the dryer overheated or the safety circuit opened. |
| Dryer control board | Amazon | Replace only if the thermistor and wiring test good and the code persists. |
When to Call a Pro
Call a professional if you are not comfortable working with electrical components or multimeter testing. A technician can safely access the thermistor, test the sensor circuit, inspect wiring and connectors, and diagnose control board faults. If the dryer has a gas heating system or if you find evidence of overheating or burned wiring, a pro should handle the repair to avoid fire or safety hazards. If you have replaced the thermistor and cleaned the vent system but the code returns, the problem may require board-level diagnosis or a less obvious wiring fault that a qualified service tech can trace.
