LG Dryer Error Codes: What They Mean and What to Do

LG dryer d80, d85, d90 and d95 codes mean the exhaust vent is roughly 80–95% blocked — clean the lint filter, the duct behind the dryer and the vent to the outside, and don't run the dryer at d90 or higher. tE1 and tE3 are temperature (thermistor) and heat faults, gAS means a gas dryer isn't heating, dE means the door switch is open and PS means the supply voltage is wrong. After the vent is cleaned, codes that return need a technician.

Try this first

  1. Clean the lint filter and the vent from the dryer to the outside hood.
  2. Electric dryers: check both halves of the 240V double breaker. Gas dryers: make sure the gas valve is on.
  3. Unplug the dryer for 5 minutes and restart.

Vent (Flow Sense) codes

CodeWhat it meansWhat you can do
d80 / d85Exhaust about 80–85% restrictedClean the full vent run; drying stays slow until you do.
d90 / d95Exhaust about 90–95% restrictedStop using the dryer until the vent is cleaned or repaired — fire hazard.
HSHumidity sensor error, or vent test run on a warm dryerRun the test cold; if HS returns, the sensor needs service.

Heat codes

CodeWhat it meansWhat you can do
tE1Thermistor (temperature sensor) errorSensor or wiring — call for repair.
tE3Heat fault — thermistor out of range, tripped thermostat or wrong voltageCheck the 240V breaker and clean the vent; then heater circuit or high-limit.
gASGas dryer not heatingGas valve on? Then igniter, flame sensor or gas valve coils — call.

Door and power codes

CodeWhat it meansWhat you can do
dEDoor not closed — door switch openClose firmly; repeats mean the door switch.
PS / nPSupply voltage incorrect or power interruptedCheck outlet and breaker; electric dryers need 240V.
F0 / IFLint filter not detectedSeat the lint filter fully.
CLChild lock on (not an error)Hold Child Lock for 3 seconds.

Codes and their meaning can vary by model and production year, and the same code can have different causes. Where sources disagree we say so; in every case the exact cause is confirmed only by a technician's on-site diagnosis. Your owner's manual has the definitive list for your model.

Stay safe

Unplug the appliance (or switch off its breaker) before touching anything inside it, and never open a sealed refrigeration system, a gas valve or a microwave. If a code points to a part, the part has to be tested before it is replaced; we do that on the $75 diagnostic visit, credited toward the repair.

Frequently asked questions

What does d90 mean on an LG dryer?

The vent is about 90% blocked. Stop using the dryer and clean or repair the vent.

Why does my LG dryer say tE3?

No heat or a temperature fault — check the breaker and vent, then the heater circuit.

Do you clean dryer vents?

We clear what we can reach at the dryer; long or rooftop runs need a vent-cleaning company.

Do you repair LG gas dryers?

Yes, including igniters, flame sensors and gas valve coils. We don't connect gas lines.
