# How to Fix LG Error tE2 (Thermistor Shorted)
The LG error code **tE2** is a serious fault that prevents the washer/dryer combination unit from completing cycles, especially drying cycles. This guide will help you quickly diagnose and resolve the issue caused by a shorted temperature sensor.

## 1. Explanation: What LG Error tE2 Means
The LG error code **tE2** signifies that the main control board (PCB) has detected an error with a temperature sensing device, known as a **thermistor**.
In the context of LG combo units displaying tE2, this almost always points to an issue with the **Dryer Thermistor**. The term “shorted” means the electrical resistance through the sensor is too low (often near zero ohms), making the control board believe the temperature is dangerously high or incorrect.
**The likely culprit is a faulty Dryer Thermistor.**

## 2. Step-by-Step Fix: Diagnosing the Thermistor
Before attempting any troubleshooting or repair, ensure the machine is safely powered off.
**WARNING:** Always unplug your LG washer/dryer from the wall power outlet before opening the machine or attempting electrical testing.
### Step 1: Locate the Dryer Thermistor
The Dryer Thermistor is typically located within the machine’s drying duct assembly, usually near the main heating element or the blower housing.
* **Access:** Depending on your model (front-loader combo unit), you may need to remove the top panel, the rear panel, or the front panel/door bellows to access the drying components.
* **Identification:** The thermistor is a small sensor, usually secured by one or two screws, with two wires leading back to the control board.
### Step 2: Test the Wiring Harness
Visually inspect the wiring running from the thermistor. Look for:
* **Chafing or Damage:** Has the wire insulation rubbed against metal housing, causing a direct short?
* **Corrosion:** Are the terminals where the harness plugs into the thermistor corroded or damp?
If the wiring is visibly damaged, replacing the harness may solve the issue. If the wiring looks fine, proceed to test the sensor itself.
### Step 3: Test the Resistance of the Thermistor
A fully functional thermistor should have a measurable resistance (ohms). A shorted thermistor (as indicated by tE2) will show extremely low resistance, often close to 0 Ohms.
**Required Tool:** Multimeter (set to measure Ohms – look for the $Omega$ symbol).
1. **Disconnect:** Unplug the wiring harness from the Dryer Thermistor terminals.
2. **Measure:** Place the multimeter probes onto the two terminals of the thermistor itself (not the wiring harness).
3. **Read the Value:**
* **Standard Reading:** At room temperature (around 77°F/25°C), most LG Dryer Thermistors should read between **8,000 to 12,000 Ohms (8kΩ to 12kΩ)**.
* **Faulty Reading (tE2):** If your meter reads close to **0 Ohms** (or an extremely low number like 100 Ohms or less), the thermistor is definitively shorted and needs replacement.
### Step 4: Replace the Thermistor
If your testing confirms the resistance is incorrect (i.e., too low, confirming the short), the part is faulty and must be replaced.
1. Unscrew the old thermistor from its housing.
2. Install the new thermistor in the same location.
3. Reconnect the wiring harness, ensuring the connection is secure.
4. Reassemble the machine panels.
5. Plug the machine back in and run a test cycle (a short drying cycle is usually sufficient) to confirm the tE2 error is cleared.
