The LG dryer codes you are most likely to see are d75, d80, d90 and d95 (a blocked vent), tE1 to tE3 (the thermistor), dE and dE4 (the door), and PS or nP (a wiring problem at the dryer). LG publishes more codes than these, and the list varies by model, so this guide covers only the codes confirmed from LG’s support library — if yours is not here, check your manual rather than guessing.
d75, d80, d90, d95: Vent blockage
LG says these codes mean the exhaust duct is restricted by about 75, 80, 90 or 95 percent. Lint in the duct, a crushed or kinked hose, or a clogged outside vent cap are the usual causes. On a gas dryer, LG notes that d80 may also point to a lack of gas supplied to the unit. Our dedicated guide, LG Dryer D80, D90 and D95 Error Codes, walks through the cleaning, and how often to clean the vent explains prevention.
tE codes: Thermistor
| Code | What LG says |
|---|---|
| tE1, tE3 | A problem was detected with the dryer’s thermistor (temperature sensor); usually cleared by a reset, and if it persists the unit needs service |
| tE2 | Also a thermistor problem, normally in cold conditions; humidity during steam cycles can cool the duct quickly and trigger it |
| tE4 to tE6 | Listed by LG as further tE variants — see your manual for model-specific advice |
A thermistor code is not a vent problem, but a clogged vent makes the dryer run hot and can make false readings more likely, so clean the vent before you decide a part has failed. See our dryer overheating guide.
dE, dE2 and dE4: Door
A dE code means the dryer door is not completely closed. Open the door, make sure the lint filter is pushed all the way in, and check that no clothing is stuck between the door and the gasket. LG’s dE2 (drawer closed but not locked) can be caused by too much laundry, items trapped in the door, or a bent or broken latch. For dE and dE4, LG’s instruction is to reset the unit (unplug it or trip the breaker, wait 5 seconds, plug back in), close the door firmly, choose a cycle and press Start; if the code comes back, service is needed.
PS and nP: Power and wiring
LG describes PS as an improper voltage in the power cord, which can happen when the white and red wires are reversed at the dryer’s terminal block, and nP as no current being detected at the heater because of a household wiring problem. Do not open the terminal block yourself unless you are qualified; call an electrician. A recently installed or moved dryer is the most likely to show these codes.
HS, F1 and AE
HS indicates a humidity sensor error; LG notes that the dryer will run for about two and a half hours on a fixed time, which can make it seem as though it is not drying. F1 (no more heat being generated in the heat exchanger) and AE (compressor problem) apply to heat-pump models and need a technician. If your dryer is simply slow, our dryer takes too long to dry guide is the better starting point.
How to reset an LG dryer
- Unplug the dryer or trip its breaker
Leave it off for at least 5 seconds; a minute is safer.
- Restore power and close the door firmly
Make sure the lint filter is seated.
- Run a short cycle
If the same code reappears straight away, treat it as a real fault.
When to call a technician
Thermistor codes that survive a reset, door latch faults, heat-pump codes and wiring codes need a professional. Weigh the quote with our dryer repair cost guide.
