What Does Error tE1 Mean?

The LG dryer error code tE1 indicates a thermistor failure, disrupting the dryer’s ability to heat and leading to inconsistent temperature readings. This error is often the result of a faulty thermistor, an open or shorted circuit, or misinterpretation of sensor signals by the control board. If the dryer drum continues to turn but no heat is produced, this could signal the need for a thermistor inspection or replacement.

Common Symptoms:

  • Dryer stops heating and displays tE1 on the control panel.
  • Drum may continue to turn but no heat is produced.
  • Error persists after simple power reset.

Possible Causes

  • Faulty thermistor (temperature sensor) (medium)
  • Open or shorted thermistor circuit / bad wiring (medium)
  • Control board (main PCB) misinterpreting sensor signal (medium)

How to Fix Error tE1

DIY Fix Power reset and basic check

  1. Unplug the dryer from power.
  2. Wait ~5 minutes.
  3. Reconnect power and attempt to run a cycle.

Technician Only Inspect and test thermistor and wiring

  1. Disconnect power to the dryer.
  2. Remove appropriate access panel to locate the exhaust thermistor.
  3. Visually inspect wiring and connectors for damage or corrosion.
  4. Use a multimeter to measure thermistor resistance and compare against model-specific specs.
  5. Replace thermistor and/or repair harness if readings are outside specification or wiring is compromised.

Parts needed: Exhaust thermistor, Wiring harness

Technician Only Control board diagnosis and replacement

  1. Confirm thermistor and wiring are functioning properly.
  2. Test board inputs and outputs related to temperature sensing circuit.
  3. Replace the main control board if confirmed faulty.

Parts needed: Main control board (PCB)

🛑 When to Call a Pro:
  • If the error persists after testing and replacing the thermistor and wiring harness.
  • If you are not comfortable performing electrical diagnostics safely.
