## How to Fix GE Error E02 (Outlet Thermistor Error)
The GE error code “E02” can be frustrating, especially when you have a load of laundry waiting. Fortunately, this error often points to a specific, fixable component. This guide will help you understand what the code means and walk you through the troubleshooting steps.

### 1. Explanation: What is Error E02?
The E02 error code is generated when your washing machine’s main control board cannot properly read the temperature from the **Outlet Thermistor**.
* **What is a Thermistor?** A thermistor is a small sensor (a resistor) whose resistance changes significantly with temperature. It is used to monitor heat and prevent overheating.
* **The Culprit:** Although the washing machine uses multiple thermistors, the E02 error most commonly refers to the **Dryer Thermistor** (sometimes called the Outlet Duct Thermistor) located in the ductwork leading out of the appliance. If this sensor malfunctions, the control board receives an out-of-range temperature signal (either too high, too low, or no signal at all), triggering the E02 error and shutting down the cycle.
**In plain English:** The machine thinks it’s overheating, but the sensor telling it that might be broken.

### 2. Step-by-Step Fix: How to Diagnose and Repair
Troubleshooting the E02 error requires checking the electrical connections and, potentially, replacing the faulty sensor.
#### Safety First!
**Always unplug the washing machine from the wall outlet and turn off the circuit breaker before performing any internal inspection or repair.**
#### Step 1: Perform a Hard Reset
Before opening the appliance, try a simple reset to clear any temporary glitches:
1. Unplug the machine from the power source.
2. Wait 5–10 minutes.
3. Plug the machine back in.
4. Start a new cycle to see if the E02 error has cleared. If it reappears immediately, proceed to Step 2.
#### Step 2: Locate and Inspect the Dryer Thermistor
The Dryer Thermistor is typically located within the exhaust duct of the washer/dryer combination unit. You may need to remove the top panel or rear access panel to gain access.
1. **Locate the component:** Identify the exhaust duct where the air leaves the unit. The thermistor is usually a small plastic or metal sensor plugged into the ductwork.
2. **Inspect wiring:** Visually inspect the wires leading to the thermistor. Look for any signs of damage, burning, or corrosion. Ensure the connectors are seated firmly into the sensor and the main control board. If you find loose wires, reconnect them firmly and test the unit again.
#### Step 3: Test the Thermistor (Advanced)
If the wiring looks good, the thermistor itself is likely defective. You can confirm this using a multimeter set to measure ohms (resistance).
1. **Disconnect the wires:** Remove the electrical connectors from the thermistor terminals.
2. **Measure resistance:** Place the probes of your multimeter onto the two terminals of the thermistor.
3. **Check for proper readings:** A working thermistor should show a specific resistance value, which varies by model but is often around **10,000 to 15,000 ohms (10k to 15kΩ)** at room temperature (70–75°F).
* **Diagnosis:** If the multimeter reads **”OL”** (Open Loop/Infinite Resistance) or **zero ohms**, the thermistor is faulty and needs replacement.
> **Tip:** If the resistance reading is wildly outside the expected range (e.g., 50kΩ), the sensor is likely failing due to temperature changes and should be replaced.
#### Step 4: Replace the Faulty Thermistor
If you confirmed the sensor is bad, replacement is straightforward:
1. Unscrew or unclip the old thermistor from the duct housing.
2. Install the new thermistor in its place, ensuring it is properly seated.
3. Reconnect the wiring harness.
4. Reassemble the panels you removed.
5. Plug the machine back in and test a cycle. The E02 error should now be resolved.
