TE1
LG tE1 on a dryer: temperature thermistor fault
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On an LG dryer, tE1 or tE3 flags a thermistor problem. LG says to unplug it, hold Start/Pause for 5 seconds without power and plug it back in. tE2 appears in cold conditions and asks you to clean the lint filter and check the vent; tE4 needs a technician.
Safety first
Stop and check this first
- A blocked exhaust vent collects hot lint: do not use the dryer with the outlet blocked or iced until it is cleared.
Safe checks you can perform
- Exact code number
- Control reset with Start/Pause
- Lint filter and exhaust vent (tE2)
Leave these tasks to a qualified professional
- Do not attempt this professional task: Thermistor measurement
- Do not attempt this professional task: Vent check and test cycle
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Thermistor measurement
What they doWith the dryer disconnected, the technician measures the thermistor with a multimeter and compares the value with LG's specification for room temperature.
They must show youthe measured value against the specification.
In writingthe result and, if the thermistor is replaced, its part number and the reason.
Vent check and test cycle
What they doThey check the exhaust vent is not blocked and, after the repair, run a full cycle to verify the code stays away.
They must show youthe clear vent and the cycle finished without the code.
In writingwhat was checked, what was replaced and the final test.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Exact code number
- Who:
- you, no tools.
- How:
- check whether it shows tE1, tE2, tE3 or tE4. LG gives different steps for each.
- Result that matters:
- which instructions apply.
- If tE1 or tE3:
- do the control reset; tE2: clean the filter and vent.
- If tE4:
- LG says professional repair; do no more tests.
- Evidence to keep:
- photo of the display.

Control reset with Start/Pause
- Who:
- you, at the plug or breaker.
- How:
- unplug the dryer or trip its breaker, hold Start/Pause for 5 seconds without power, reconnect it and run a cycle, as LG says.
- Result that matters:
- whether the cycle finishes without the code.
- If it finishes:
- it was a one-off.
- If it returns:
- LG says to request repair.
- Evidence to keep:
- note of the reset and the result.

Lint filter and exhaust vent (tE2)
- Who:
- you, no tools.
- How:
- clean the lint filter and check the vent and outside outlet for lint, snow, ice or frost, as LG says for tE2.
- Result that matters:
- whether air can flow freely.
- If there was a blockage or ice:
- clear it and run a cycle.
- If it is clear and the code persists:
- request repair.
- Evidence to keep:
- photo of the filter and the outside outlet.

What it means
LG defines tE1 and tE3 as a thermistor problem, the sensor that measures air temperature, and suggests a control reset: remove power, hold Start/Pause for 5 seconds and reconnect. tE2 is a thermistor error in cold conditions: LG says to clean the lint filter and check the exhaust vent for clogs, snow, ice or frost. tE4 is thermistor out of range and LG sends it to professional repair. The code does not prove the thermistor needs replacing: its connection can also be at fault.
Warnings and stop conditions

Symptoms and causes
Probable causes · in order
- One-off control glitchPossible
Fits tE1 or tE3 if the code clears after the control reset LG suggests.
Evidence: LG USA dryer error code list
- Cold or blocked air outletPossible
This is the tE2 case: LG links it to cold and to vents blocked by lint, snow, ice or frost.
Evidence: LG USA dryer error code list
- Failed thermistor or connectionPossible
Suspected if the code returns after the reset, and always with tE4, which LG defines as out of range. Only the technician confirms it.
