LG Dryer tE2 Error
Not tE1 with a different digit: LG gives tE2 its own cause (cold, steam humidity) and its own procedure. Borrowing tE1's reset for tE2 skips the step LG actually prescribes.
What to check first
- tE2 = thermistor error, cold conditions or steam humidity (LG US).
- LG's procedure is a cycle, not a reset: Steam Fresh → More Time to “big” → Start.
- UK list adds: clean filter, check the vents.
- Recurs after the reset → service.
A tE2 code is a thermistor error with a documented trigger: LG's US list says it normally occurs during cold conditions, and explains the steam version — using the steam options (Steam Fresh, Steam Sanitary, or a steam option on other cycles) creates extra humidity in the duct, and that humidity can cool the duct faster after cycles, tripping the thermistor reading. Its procedure is a specific cycle, not a generic reset: power on, select Steam Fresh, press More Time until “big” shows, then Start. Its UK list adds the vent-path checks (clean filter, clear vents) before the reset question. A tE2 that recurs after the reset is service.
Safety first
- tE2's context is cold — a dryer in an unheated space in winter is the textbook setup. Do not respond by heating the room with the dryer running unattended, and do not disable or cover sensors to “warm” them.
- Stop condition: stop using the machine and unplug it — and do not run it again until it has been checked — if you smell burning, see smoke, find damaged electrics (a scorched plug, a melted or cut cable), or water is leaking in quantity.
Common causes
Cold conditions
LG's US list: the tE2 error normally occurs during cold conditions. A thermistor reading a genuinely cold duct can fall outside the range the control expects — the code is the reading, faithfully reported.
Steam humidity cooling the duct
LG's mechanism, in its words: extra humidity created in the duct by the steam cycles can cool the duct faster after the cycle — and the thermistor trips on the result. Steam-heavy use followed by a tE2 is the pattern LG describes.
A restricted vent path (UK list)
LG's UK list routes tE2 through the filter and vents first: a clean lint filter and a clear exhaust path are its opening checks, in the same four-area pattern as the d codes.
Step-by-step checks
- Run LG's prescribed cycleTurn the power ON, select the Steam Fresh cycle, press the More Time button until “big” is displayed, then press Start/Pause. (LG US's exact procedure for tE2.)
- Clean the lint filter (UK list)Ensure the lint filter is clean — LG UK's method: warm water and a soft brush, dried fully before reinstalling.
- Check the vents (UK list)Check the outside outlet flappers move freely (run an Air Dry cycle and watch them fully open) and remove any lint buildup — the same outside check as the d-code pages.
- Recurs after the reset steps? Book serviceLG US's endpoint: if the tE2 code recurs after resetting the unit, the unit will require service.
When to call a technician
Service is LG's stated endpoint for a tE2 that recurs after its procedure. Quote the code and the context — cold room, or after steam cycles — because LG's own definition of tE2 is contextual, and the context confirms the diagnosis.
Model differences
| What you have | What changes |
|---|---|
| No steam cycles on your model | The cold-conditions half of LG's definition still applies; the Steam Fresh procedure may not exist on your panel. Work the UK list's filter and vent checks, and let the model manual settle the procedure — do not substitute tE1's reset silently. |
| Display reads tE1 or tE3 | Different entry, different procedure — the tE1 / tE3 page. |
| Display reads tE4 | LG UK's out-of-range code, straight to service — the tE4 page. |
One-page checklist — tE2
- Code read as tE2 (not tE1 — procedures differ)
- Context noted: cold conditions and/or recent steam cycles
- LG's prescribed Steam Fresh / More Time / “big” cycle run
- Filter cleaned and vents checked (UK list)
- Code recurs → service booked, context quoted

Frequently asked questions
Why does cold weather cause tE2?
LG's US list says the tE2 error normally occurs during cold conditions: the thermistor reads the duct temperature, and a cold-soaked duct reads outside the expected range. Its second mechanism is steam — extra humidity from steam cycles cools the duct faster afterwards, with the same result.
Can I just use the tE1 reset for tE2?
LG gives tE2 its own procedure — the Steam Fresh / More Time / “big” cycle — and its UK list adds filter and vent checks. The tE1 factory reset is a different code's instruction; LG does not publish it for tE2, so this page does not borrow it as the fix (the recurrence line still stands: a tE2 that recurs after resetting is service).
tE2 keeps coming back every winter. Service or normal?
LG's endpoint is explicit: if the tE2 code recurs after resetting the unit, the unit will require service. A seasonal pattern explains the code; it does not convert a recurring code into a normal one.
