tE

Thermistor Error

Severity

Medium

When a LG Dryer shows tE on its display, the internal diagnostic system has flagged a condition known as "Thermistor Error". Most repairs for this code are straightforward and can be completed at home.

Owner's Summary

Your LG dryer is tumbling but not producing heat. The temperature sensor or the heating element has likely failed. Testing the inexpensive thermistor first can save you from buying a more expensive part unnecessarily.

Symptoms

LG dryer not heating, running cold cycles, tE error displayed

Common Causes

Open or shorted NTC thermistor
Failed heating element
Wiring fault to thermistor
Burned heater relay on PCB

How to Fix

1 Test thermistor resistance — should be approximately 10k ohms at room temperature
2 Test heating element continuity
3 Inspect wiring harness to heater assembly
4 Replace faulty component based on test results

Tools You'll Need

Multimeter Flashlight

These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.

Technical Explanation

The EBR control board reads thermistor resistance to regulate the heating cycle. tE indicates the resistance value is outside the valid operating curve, causing the board to disable the heater relay to prevent uncontrolled heating or operation with no temperature feedback.

Is It Safe to Keep Using?

No fire risk from this code itself. Fix within a week to restore normal drying performance.

Technician's Pro Tip

LG dryer thermistors are usually clipped near the heating element or exhaust duct outlet — accessible by removing the rear panel. Always disconnect power before testing to avoid a false reading from residual voltage.

Frequently Asked Questions

What does error code tE mean on a LG Dryer?

Code tE on a LG Dryer indicates "Thermistor Error." In practice, the most common trigger is open or shorted NTC thermistor. Severity is rated medium, and typical repair costs range from $15 to $200.

Can I fix tE myself, or do I need a technician?

Many cases of tE can be resolved without a technician. The first step to try: test thermistor resistance — should be approximately 10k ohms at room temperature. If that doesn't clear the code, work through the remaining steps in the "How to Fix" section above before assuming a part needs replacing.

Is it safe to keep using my dryer with code tE showing?

No fire risk from this code itself. Fix within a week to restore normal drying performance.

How much does it cost to repair tE on a LG Dryer?

Repair costs for code tE typically range from $15 to $200. Thermistor: $15–$40; Heating element: $50–$150; PCB: $80–$200. Costs on the low end usually reflect a DIY fix with no parts required, while the high end reflects a part replacement plus professional labor.
