# How to Fix Kenmore Washing Machine Error tE (Heating Error)

The “tE” error code on most modern Kenmore washing machines (especially those manufactured by LG) indicates a **Temperature Error**. This is a heating circuit fault, almost always related to the sensor that monitors the water temperature.

The good news is that this error is often caused by a relatively inexpensive part that is easy to replace: the **Thermistor**.

## 1. Explanation: What does the “tE” Code Mean?

When your Kenmore washer displays “tE,” it means the machine cannot accurately read or monitor the water temperature inside the tub.

**Key Issues it Indicates:**
1. **Faulty Thermistor:** The temperature sensor (thermistor) is providing an incorrect resistance reading to the control board (PCB). This is the most common cause.
2. **Wiring Harness:** Damaged or corroded wiring running between the thermistor and the main control board.
3. **Control Board Failure (Rare):** The main board itself has failed to process the temperature input correctly.

Because the washer cannot confirm the temperature, it will often stop the cycle, drain the water, or refuse to start the heating sequence as a safety measure.

## 2. Step-by-Step Fix: Diagnosing the Thermistor

The best way to resolve the “tE” error is to test the resistance of the thermistor to ensure it is functioning correctly.

### **⚠️ Safety First!**

Before attempting any repairs, you must:
* **Unplug the washer completely** from the wall outlet.
* Turn off the hot and cold water supply valves.
* Move the machine away from the wall to access the rear panel.

### Step 1: Access the Heating Assembly

The thermistor is usually located near the heating element, typically attached to the bottom or lower back of the tub. On most Kenmore models, you will need to remove the back access panel.

1. Locate and remove the screws holding the **rear access panel** in place.
2. Set the panel aside.
3. Look for the **heating element assembly** located near the bottom of the stainless steel tub.

### Step 2: Locate and Disconnect the Thermistor

The thermistor is a small sensor, often black or white plastic, usually clipped or screwed directly into the tub near the heating element.

1. Identify the wires leading to the thermistor.
2. Gently pull the wires or connector plug off the sensor. You may need a small flathead screwdriver to gently release the clip.
3. If the thermistor is secured by a clip or screw, remove it and carefully pull the sensor out. Be prepared for a small amount of water to leak out when the sensor is removed.

### Step 3: Test Resistance using a Multimeter

You will need a standard digital multimeter set to the **Ohm (Ω) scale**, specifically the 20k setting.

1. **Set the Multimeter:** Turn the dial to the **kilo-ohm (kΩ) scale**, usually 20k or Rx10k.
2. **Apply Probes:** Touch the multimeter probes to the two terminals of the thermistor. The polarity doesn’t matter for resistance testing.
3. **Check the Reading:** At room temperature (around 77°F or 25°C), a healthy Kenmore thermistor should read approximately **10,000 Ohms (10kΩ)**.

**Interpreting Your Results:**

### Step 4: Installation and Test

If the thermistor failed the resistance test, it must be replaced.

1. Install the new thermistor in the exact location of the old one, ensuring the rubber gasket (if present) is seated properly to prevent leaks.
2. Reconnect the wiring harness firmly.
3. Replace the rear access panel.
4. Plug the machine back in and run a short cycle with hot water to ensure the “tE” error is cleared.

## 3. Call to Action

If your diagnosis confirms the thermistor is the failed component, replacement is necessary to clear the tE code.
