Quick Answer: What Does LG Dryer Error Code TE1 Mean?
LG dryer error code TE1 means the dryer has detected an abnormal temperature reading. This usually points to a faulty thermistor (temperature sensor), wiring issue, or a problem in the heating circuit.
This safety feature is built into dryers made by LG Electronics to prevent overheating or unsafe operation.
Symptoms You’ll Notice
Dryer stops mid-cycle
Dryer will not start
No heat or inconsistent heat
TE1 code appears immediately after power-on
Clothes remain damp even after long cycles
Main Causes of LG Dryer TE1 Error
Most common reasons include:
Failed thermistor (temperature sensor)
Loose or damaged sensor wiring
Moisture or lint buildup near sensor
Control board misreading temperature
Overheating due to restricted airflow (indirect cause)
Fast Troubleshooting Checklist (DIY)
Step 1: Power Reset
Unplug dryer for 5–10 minutes
Plug back in and restart
✔ If TE1 disappears, it was a temporary glitch
Step 2: Check Airflow (Important)
Restricted airflow can cause temperature spikes.
Clean lint filter
Inspect vent hose
Make sure outside vent opens properly
Step 3: Inspect the Thermistor
Unplug dryer
Remove rear or front panel (model dependent)
Locate temperature sensor near the blower or heater
Check for loose wires or corrosion
⚠️ If the sensor looks burned or damaged, it must be replaced.
Step 4: Test the Thermistor (Advanced)
Use a multimeter
Normal resistance is usually around 10k ohms at room temperature
No reading or infinite resistance = bad sensor
Can You Use the Dryer With a TE1 Error?
No. Running the dryer with a TE1 error can:
Cause overheating
Damage heating components
Trip breakers repeatedly
Create safety risks
The dryer may lock itself to prevent damage.
When to Call a Technician
Call for professional service if:
TE1 returns after reset
Thermistor tests bad
Wiring looks burned
Control board may be faulty
Sensor replacement is usually affordable, but control board issues are more complex.
Cost to Fix LG Dryer TE1 Error (Approx.)
Thermistor replacement: Low to moderate
Wiring repair: Low
Control board replacement: High
Early repair saves money by preventing bigger failures.
Prevention Tips
Clean lint filter after every load
Deep clean vents every 6–12 months
Do not overload dryer
Ensure proper airflow at all times
Good airflow keeps temperature readings stable.
LG dryer error code TE1 is a temperature sensing error, most often caused by a faulty thermistor or wiring issue. A quick reset and airflow check may help, but persistent TE1 errors usually require sensor replacement or professional repair.
