tE2 — Outlet thermistor / temperature out of range
tE2 indicates the outlet (exhaust) thermistor is reading temperatures outside the expected range — most commonly during cold start conditions, on Steam cycles, or with severely restricted airflow.

How to fix it
- Unplug for 60 seconds and hold Start/Pause for 5 seconds to attempt a soft reset.
- Clean the lint filter and confirm exhaust duct flows freely.
- If the dryer is in a sub-freezing space, warm the area or move the dryer indoors and retry.
- Unplug, remove the back/top panel, and locate the outlet thermistor on the blower housing.
- Measure resistance at room temperature — should be approximately 10 kΩ at 25°C; if open or far off, replace the thermistor.
- Check the harness from thermistor to main board for damaged pins, then reassemble and retest.
Why it happens
Typical signs: tE2 on display · Cycle ends early without drying · Drum is cold or only briefly warm · Error returns within minutes of restart
- Restricted airflow Clogged lint filter or duct prevents heated air from reaching the sensor.
- Cold ambient location Dryer in an unheated garage below thermistor's valid start range.
- Failed thermistor Out-of-range resistance or open winding in the outlet thermistor.
- Loose thermistor wiring Connector unseated or wire chafed against cabinet.
- Bad main control board Board misreads a healthy thermistor.
