When your LG dryer shows the HE error code, it means the unit is having a heating error. In simple terms, the dryer is not reaching the correct temperature to dry your clothes. This is one of the most common issues we see in Austin homes — especially during heavy laundry seasons.
Below we explain what the HE code means, why it happens, and when it’s time to call a professional.
🔍 What Does the LG Dryer HE Error Mean?
The HE code stands for Heating Error.
It appears when the dryer detects that the temperature is too low or not increasing as expected, even though the cycle is running.
In gas and electric LG dryers, this usually points to a problem with:
- The heating element
- The thermostat
- The thermistor
- Airflow restrictions
- Gas ignition issues (for gas models)
⚠️ Common Causes of HE Error in LG Dryers
1️⃣ Blocked Vent or Airflow Restriction
This is the #1 cause we find in Austin homes.
A clogged vent prevents hot air from circulating, causing the dryer to overheat or fail to heat.
Symptoms:
- Dryer runs but clothes stay wet
- Dryer feels very hot on the outside
- Takes longer than normal to dry
2️⃣ Failed Heating Element (Electric Models)
If the heating element is burned out, the dryer cannot generate heat.
Signs:
- Dryer tumbles but produces zero heat
- Burning smell before it stopped heating
3️⃣ Bad Flame Sensor or Ignitor (Gas Models)
For gas dryers, if the ignitor or flame sensor fails, the burner will not ignite.
Signs:
- Clicking sound but no heat
- Dryer warms for a few seconds then stops heating
4️⃣ Thermostat or Thermistor Failure
These components monitor and regulate temperature.
If they fail, the dryer misreads temperatures and triggers the HE error.
5️⃣ Lint Buildup Inside the Dryer
Not just the vent — lint accumulation inside the dryer can cause overheating and airflow issues.
🧰 How to Fix the LG HE Error Code (Simple Steps)
✔ 1. Reset the Dryer
Sometimes the unit simply needs a reboot.
Steps:
- Unplug the dryer
- Wait 5 minutes
- Plug it back in
- Restart a cycle
If the error returns, move to the next steps.
✔ 2. Check the Vent & Airflow
This solves the problem in MOST homes.
- Pull the dryer away from the wall
- Disconnect the vent
- Clean lint from the hose and wall outlet
- Make sure airflow is strong
If the hose is crushed, replace it.
✔ 3. Clean the Lint Filter Housing
Remove the lint filter and clean the slot with a vacuum.
✔ 4. Inspect the Heating Element (Electric Dryers)
A technician can test it for continuity and replace if needed.
✔ 5. Check the Ignitor / Flame Sensor (Gas Dryers)
If the ignitor isn’t glowing or the flame sensor is defective, the dryer won’t heat.
✔ 6. Test Thermostat & Thermistor
These parts should be tested with a multimeter.
If readings are out of range, replacement is required.
🛠️ When to Call a Professional in Austin
If you’ve cleaned the vent and checked basic airflow but still get the HE error, it’s time to call a certified technician.
We recommend service if:
✔ Dryer runs but does not heat
✔ Error comes back after resetting
✔ Clothes take a long time to dry
✔ The dryer overheats or has burning smell
✔ You have a gas dryer (dangerous to DIY)
