# How to Fix Samsung Washing Machine Error tE (Thermistor Error)
The `tE` error code is one of the most common issues encountered on Samsung **Washer/Dryer Combo** units, specifically related to the drying function. This guide will help you diagnose the problem and replace the faulty component.

## 1. Explanation: What does the tE Code Mean?
The `tE` code stands for **Thermistor Error**.
A thermistor is a simple electrical sensor used to monitor and regulate temperature. When the washing machine’s main control board (PCB) displays `tE`, it means the machine is receiving an inconsistent, open, or shorted reading from the temperature sensor.
**In Samsung Washer/Dryer Combos, this error almost always points to the failure of the DRYER THERMISTOR.**
If the control board cannot accurately measure the temperature of the drying air, the machine will shut down the heating element immediately to prevent a fire or overheating, leading to cycles that never complete the drying phase.

## 2. Step-by-Step Fix: Diagnosing the Thermistor
Before assuming hardware failure, always attempt a full reset.
### Step 1: Perform a Power Reset
Sometimes, the control board reads a temporary glitch. A hard reset can clear the error.
1. **Unplug** the washing machine completely from the wall socket.
2. Wait 5 to 10 minutes. This allows the internal control board to fully discharge and reset.
3. Plug the unit back in and attempt a short drying cycle.
If the error immediately reappears, proceed to hardware inspection.
### Step 2: Check Vents and Environment
While a thermistor error is usually electronic, poor airflow can cause the thermistor to overheat or read abnormally high, sometimes triggering the code.
1. **Clean the Lint Filter:** Thoroughly remove all lint, dust, and debris from the machine’s internal lint filter.
2. **Inspect Exhaust:** If your combo unit uses a vent, ensure the exhaust hose is not crushed, blocked, or filled with lint. Restricted airflow is the number one cause of poor drying performance and can stress the thermistor.
### Step 3: Testing and Replacing the Dryer Thermistor (The Core Fix)
This process requires a basic multimeter and access to the interior components of the machine. **Always unplug the appliance before beginning any internal repair.**
#### Location of the Thermistor:
The dryer thermistor is typically located near the exhaust duct or attached directly to the metal housing of the heater assembly within the machine. You will usually need to remove the top panel, sometimes the back panel, and occasionally the front bezel, depending on your model configuration.
#### Using a Multimeter:
1. **Access the Thermistor:** Locate the sensor. It will be a small, plastic component with two wires attached to the ductwork. Disconnect the electrical connector plug leading to the sensor.
2. **Set Multimeter:** Set your multimeter to measure resistance (Ohms, Ω). Use the 20kΩ setting.
3. **Test Resistance:** Touch the multimeter probes to the two terminals of the thermistor.
#### Interpreting the Readings:
| Reading Type | Diagnosis | Action |
| :— | :— | :— |
| **10kΩ – 12kΩ** | Good Sensor (at room temperature) | Sensor is likely fine. Check the wiring harness or control board instead. |
| **0Ω (Zero)** | Short Circuit | Thermistor is bad and must be replaced. |
| **OL (Open Line / Infinity)** | Open Circuit | Thermistor is bad and must be replaced. |
*Note: The resistance value is temperature-dependent. If the sensor is tested immediately after a hot cycle, the resistance will be lower. If the reading is extremely high (OL) or nonexistent (0), the sensor is faulty.*
#### Replacement:
If the thermistor failed the resistance test, it must be replaced. It is usually held in place by one screw or a metal clip. Install the new thermistor, reconnect the wiring harness, reassemble the machine, and test a drying cycle.
