LG Dryer tE2 Error Code — What It Means
tE2 is a thermistor error on the second temperature sensor, often the one used during cold conditions or steam cycles. The control board sees a reading it cannot trust and stops the cycle.
Like tE1, a one-time tE2 can be a glitch, but a code that returns points to the sensor or its connection.
Common Causes
- Failed thermistor The second temperature sensor drifts out of range or goes open.
- Loose connector A corroded or unseated plug at the sensor breaks the signal to the board.
- Cold room conditions Very cold air at startup can trip tE2 on some steam models until the room warms.
- Damaged wiring A pinched or chafed wire near the sensor shorts or opens the circuit.
- Faulty control board If the sensor and wiring test good, the board input may be the cause.
Step-by-Step Fix
- Power cycle the dryer by unplugging it for one minute to clear a one-time glitch.
- Warm the room if the dryer sits in an unheated space and try the cycle again.
- Unplug and open the cabinet to reach the thermistor on the blower or heater duct.
- Reseat the connector and clean any corrosion at the sensor plug.
- Test the thermistor with a multimeter, which should read near 10k to 11k ohms at room temperature.
- Replace the thermistor if the reading is far off or reads open.
- Reassemble and run a steam or normal cycle to confirm the code is gone.
Parts Often Needed
| Part | Notes |
|---|---|
| LG dryer thermistor assembly | Amazon | Confirm the part matches your steam model, since LG uses more than one sensor. |
| LG dryer wiring harness connector | Amazon | Only needed if the sensor plug is burnt or corroded. |
| LG dryer main control board | Amazon | Last resort after the sensor and wiring both test good. |
When to Call a Pro
If the thermistor reads in spec and the wiring is clean but tE2 keeps returning, the control board is the likely cause. That is a good point to bring in an appliance pro before buying a costly board.
