LG Dryer TE1 Error Code: Exhaust Thermistor Failure

Quick Answer

TE1 on an LG dryer means the exhaust thermistor has failed or its circuit is broken. The thermistor is a small resistance sensor on the exhaust duct inside the rear panel. Test it with a multimeter: it should read 40k ohms at 32°F decreasing to 3k ohms at 140°F.

TE1 on an LG dryer means the exhaust thermistor has failed or its circuit is broken. The thermistor is a small resistance sensor on the exhaust duct inside the rear panel. Test it with a multimeter: it should read 40k ohms at 32°F decreasing to 3k ohms at 140°F. At room temperature (77°F) expect roughly 10k ohms. If it reads OL or 0, replace part 6323EL2001B. Also check the connector for corrosion and the wire harness for breaks before ordering parts.

What Does the TE1 Code Mean?

The exhaust thermistor is open or shorted. The dryer cannot measure temperature and will fault until it is replaced.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Thermistor element failed from heat fatigue (70%)40%
Wire harness break between thermistor and control board (10%)36%
Thermistor connector corroded at terminals (20%)24%

Symptoms You May Notice

  • TE1 displayed on control panel
  • Dryer stops mid-cycle with error
  • Dryer runs but will not heat
  • Intermittent TE1 code that clears then returns

Can you reset a Lg dryer to clear the TE1 code?

Unplug the dryer for 10 seconds after replacing the thermistor to clear the fault from memory. The TE1 code will not return if the repair was successful. If it does return, the problem is in the wiring or control board, not the thermistor itself.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Unplug the dryer from the wall outlet

Unplug the dryer from the wall outlet. Remove the rear access panel using a Phillips screwdriver - typically 6-8 screws along the perimeter.

2

Locate the exhaust thermistor

3

Disconnect the thermistor leads

4

If thermistor tested good

5

Replace the thermistor

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

What is the correct resistance for an LG dryer thermistor?
At room temperature (77°F), the LG exhaust thermistor should read approximately 10,000 ohms. The full range is 40,000 ohms at 32°F decreasing to 3,000 ohms at 140°F. Any reading of OL (open circuit) or near 0 ohms indicates a failed thermistor.
Can a dirty exhaust duct cause a TE1 error?
Indirectly, yes. A severely clogged duct (D95) can cause the dryer to overheat, which accelerates thermistor failure. If you are getting both D80/D90/D95 and TE1, clean the duct first, then test the thermistor.
Is TE1 safe to ignore temporarily?
No. Without a working thermistor the dryer has no way to detect overtemperature conditions in the exhaust path. Running it with TE1 active creates a fire hazard risk. Replace the thermistor before using the dryer again.
