GE Dryer E31 Error Code Explained | Causes and Fix Guide

Quick Answer

The E31 error code on a GE dryer usually indicates a thermistor (temperature sensor) failure.

This means the dryer cannot properly detect or regulate temperature, which can stop the drying cycle.

Why This Error Matters

Your dryer depends on accurate temperature readings to:

• Dry clothes evenly

• Prevent overheating

• Protect internal components

When the thermistor fails, the dryer may stop working altogether or behave unpredictably.

Signs You May Notice

Before or along with the E31 error, you might see:

• Dryer not heating properly

• Cycle stopping mid-way

• Clothes coming out damp

• Dryer running but not drying

Main Causes of E31 Error

1. Faulty Thermistor

The most common cause. The sensor may be damaged or worn out.

2. Loose or Damaged Wiring

Connections between the thermistor and control board may be disrupted.

3. Control Board Issue

In rare cases, the main control board misreads the thermistor data.

Step-by-Step Fix

Reset First (Always Start Here)

Unplug the dryer for 5 minutes, then restart it.
Sometimes the error is just a temporary glitch.

Check the Thermistor

• Disconnect power

• Locate the thermistor (usually near the blower housing)

• Test with a multimeter

If readings are abnormal, replace it.

Inspect Wiring

• Look for loose connectors

• Check for burnt or broken wires

• Secure or replace as needed

Replace the Thermistor

If faulty, replacing the thermistor is the most effective fix.
It is relatively inexpensive and easy to install.

Evaluate the Control Board

If the issue continues after replacing the thermistor, the control board may be defective.
This step usually requires professional help.

Cost of Repair (Estimated)

• Thermistor replacement: Low cost

• Wiring repair: Low to moderate

• Control board replacement: Higher cost

Prevention Tips

• Clean lint filter regularly

• Avoid overloading the dryer

• Keep vents clear for proper airflow

• Do routine maintenance checks

The GE dryer E31 error code is usually not serious and often points to a faulty thermistor.

With a quick diagnosis and a simple replacement, your dryer can be back to normal in no time. Acting early prevents bigger and more expensive problems later.
