LG Dryer tE2 — What It Means & How to Fix It
tE2 is LG's temperature-sensor code that shows up in cold conditions — typically when outside air flows back through the exhaust during a steam cycle and cools the duct too fast — so it usually points to the vent and the weather rather than a broken sensor.
What this code means
The thermistor expects the duct to warm up at a certain rate, and tE2 appears when it cools down too quickly, which most often happens in winter on SteamFresh, Steam Sanitary, or Steam Option cycles. Cold air sneaking back through an open or leaky vent flap is the usual trigger. It's the same sensor behind tE1, but tE2 specifically flags this cold-air condition.
tE2 is the cold-weather member of LG's thermistor family, distinct from tE1 and tE3, which are general sensor faults. If you see it outside of steam cycles or in warm conditions, treat it like tE1 and reset; a code that persists after the vent is sorted needs a technician.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Cold outside air drawn back through the exhaust vent | Very common | Yes — no tools |
| Vent flap or louvers stuck open, or blocked by snow or frost | Common | Yes — no tools |
| Running steam cycles in a very cold laundry area | Common | Yes — settings |
| Genuine thermistor fault if it persists in normal conditions | Occasional | No — technician job |
What you can try yourself
- Check the outdoor vent flap: make sure it opens when the dryer runs and closes fully afterward, and clear any snow, frost, or lint holding it open.
- Confirm the exhaust duct isn't leaking cold air back into the dryer and that the louvers seal properly between cycles.
- If the laundry room is very cold, warm the space or postpone steam cycles until conditions improve — steam options are the most sensitive to this.
- Unplug the dryer for a couple of minutes, restore power, and rerun the cycle to clear the code.
- If tE2 persists in normal, non-cold conditions, treat it as a thermistor fault and call a technician.
When to call a technician
- tE2 keeps appearing even in mild weather and on non-steam cycles.
- The vent flap is sound and sealing but the code returns.
- The dryer also runs cold or ends cycles early.
Typical professional repair cost: If it isn't the vent or the weather, a thermistor replacement runs roughly $130–$250 with labor.
Frequently asked questions
Why does my LG dryer show tE2 in winter?
tE2 is a cold-condition thermistor code. In cold weather, outside air can flow back through the exhaust vent and cool the duct faster than the sensor expects, especially during steam cycles. Make sure the outdoor vent flap opens and closes properly and isn't propped open by frost or lint.
How do I get rid of the tE2 code on an LG dryer?
Sort out the cold-air path first: check that the outdoor vent flap seals, clear any snow or frost, and avoid steam cycles in a freezing laundry room. Then unplug the dryer for a couple of minutes and restart. If it only happens in the cold, that's expected behavior rather than a broken part.
Is tE2 a serious problem?
Usually not — it's most often the dryer reacting to cold air rather than a hardware failure, and it clears once the vent seals and the temperature comes up. It only becomes a repair if tE2 keeps returning in normal conditions, which would point to the thermistor itself.
Related LG codes
- LG Dryer d80 d80 is LG's Flow Sense system telling you the exhaust duct is about 75–80% restricted: the dryer keeps running but dries slowly, so treat it as an early warning to clean the lint filter and the full vent line before the blockage gets worse.
- LG Dryer d90 d90 — and the more severe d95 — is LG's Flow Sense system reacting to a badly blocked exhaust of 90% or more by cooling the dryer down and stopping the cycle, so unlike the milder d80 you have to clear the vent before it will run properly again.
- LG Dryer dE dE tells you an LG dryer can't confirm its door is latched shut, so it won't spin the drum — usually because laundry is caught in the seal, the door wasn't pushed firmly enough, or the door switch is worn.
- LG Dryer tE1 tE1, and the related tE3, means an LG dryer has detected a problem with its thermistor — the sensor that tracks drum temperature — so a factory reset clears a one-off glitch, but a code that keeps returning points to a failing sensor for a technician.
