LG Washing Machine: thermistor error
What is this symptom?
Experiencing an LG washing machine thermistor error? The tE error code signals a fault with the temperature sensor or its circuit, hindering the washer's ability to accurately detect and manage water temperature. This issue can lead to ineffective washing cycles and failure to heat water, causing interruptions during your laundry routine.
Important Tips for LG Models
- The tE error code on LG washing machines specifically indicates a thermistor or temperature-related error in temperature sensing or heating circuitry
Possible Causes
Faulty thermistor (temperature sensor)
How to Identify: tE error code displayed; washer fails to accurately read water temperature; multimeter resistance out of expected range
Part: Thermistor (temperature sensor)
Faulty heating element affecting temperature detection
How to Identify: tE error shown, water does not heat; visual or continuity test reveals open/broken element
Part: Heating element
Loose/damaged wiring or connectors between thermistor/heater and control board
How to Identify: Intermittent error, visual signs of frayed wires or corrosion; continuity issues on multimeter
Part: Wiring harness/connector
Main control board fault affecting temperature circuit
How to Identify: Error persists after replacing sensor and heater; other unrelated errors also present
Part: Main control board
DIY Solutions
Reset washer and check settings
- Turn off and unplug the washing machine
- Wait 3–5 minutes then plug back in and restart a cycle
- Ensure wash cycle selected includes hot/warm water if applicable
Inspect and test thermistor and wiring
- Unplug washer and access area near bottom of drum (rear or front panel depending on model)
- Visually inspect thermistor wiring and connectors for damage or corrosion
- Use a multimeter to test thermistor resistance (reference expected values per model) and wiring continuity
- If thermistor readings are out of range and wiring is intact, plan for sensor replacement
Next step
Choose the next step for thermistor error
Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Most relevant component to inspect
Temperature Sensor
Monitors the internal temperature to ensure correct operation and prevent overheating.
- Typical part-only price
- $15 - $35
- DIY difficulty
- Easy
- Estimated time
- 15-30 mins
Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Heating Element
Heats the water or air inside the appliance to the required temperature.
Wiring Harness
Connects controls, sensors, motors, and other electrical components inside the appliance.
Main Control Board
The central brain of the appliance that controls all components, cycles, and timings.

Common Issues Reported by Users
- Faulty thermistor (temperature sensor) causing inaccurate readings
- Damaged wiring or connectors in the thermistor circuit
- Control board malfunction affecting thermistor readings
User Suggested Solutions
-
Test the thermistor with a multimeter for resistance. If it shows an open circuit or incorrect resistance, replace it. Disconnect power, remove the old thermistor, and install the new one. Reconnect power and run a test cycle.
-
Inspect the wiring harness connected to the thermistor for any visible damage or loose connections. Repair or replace any damaged wires and ensure all connections are secure.
-
Check the control board for any signs of damage or burnt components. If damaged, replace the control board. This may require professional assistance due to complexity.

threw a TE code, bearings possibly shot
The issue is likely with the thermistor or a break in the harness, not the bearings.
