Lg Washing Machine: thermistor error

Professional Repair Guide

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.

Urgency: Medium

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

Easy 5–10 minutes
  1. Turn off and unplug the washing machine
  2. Wait 3–5 minutes then plug back in and restart a cycle
  3. Ensure wash cycle selected includes hot/warm water if applicable
⚠️ Safety First: Ensure machine is unplugged before reconnecting power

Inspect and test thermistor and wiring

Moderate 30–60 minutes
Tools Needed: Multimeter, Screwdrivers
  1. Unplug washer and access area near bottom of drum (rear or front panel depending on model)
  2. Visually inspect thermistor wiring and connectors for damage or corrosion
  3. Use a multimeter to test thermistor resistance (reference expected values per model) and wiring continuity
  4. If thermistor readings are out of range and wiring is intact, plan for sensor replacement
⚠️ Safety First: Disconnect power before starting

Professional Repairs

Replace thermistor (temperature sensor)

Estimated Cost: $30–$90

Replace heating element

Estimated Cost: $40–$120

Repair or replace control board

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

  1. 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.

  2. 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.

  3. 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.
