LG dryer error TE3 – Thermistor problem  

The TE3 error code on LG dryers indicates a problem with the thermistor, a component that monitors and regulates the dryer’s temperature. This error may cause the dryer to overheat or fail to heat at all.  

What causes the TE3 error? 

1. Faulty thermistor 

The thermistor may have failed due to age, wear, or exposure to high heat.  

2. Wiring issues 

Loose or frayed wires connecting the thermistor to the control board can disrupt communication, triggering the error.  

3. Control board malfunction  

The control board might be misinterpreting the signals from a functional thermistor.  

How to fix the TE3 error?

Step 1. Inspect the thermistor 

– Locate the thermistor near the dryer’s blower housing. 

– Test it with a multimeter for continuity. Replace the thermistor if it shows no continuity or irregular readings.  

Step 2. Check the wiring

– Examine the wiring connecting the thermistor to the control board for damage or disconnection. Secure loose wires or replace damaged ones.  

Step 3. Inspect the control board

– If the thermistor and wiring are intact, the issue might be with the control board. A technician will need to diagnose and repair or replace it.
