Dryer Error Code E3 – What It Means and How to Fix It

If your dryer suddenly stops working and displays Error Code E3, it’s usually a sign that your appliance is overheating or has a temperature sensor issue. While this can be frustrating, the good news is that it’s often fixable without replacing the entire dryer.

What Does Dryer Error Code E3 Mean?

The E3 error typically points to a faulty thermistor (temperature sensor) or restricted airflow. When the dryer detects that it’s running too hot or cannot read the temperature correctly, it shuts off to prevent damage or fire risk.

Common Causes of E3 Error
1. Clogged lint filter or vent – When lint builds up, it blocks airflow and causes overheating.
2. Blocked exhaust duct – The duct may be kinked or full of lint buildup.
3. Faulty thermistor – The temperature sensor could be sending incorrect readings.
4. Malfunctioning control board – In rare cases, the circuit board may be at fault.

How to Fix Dryer Error Code E3

Step 1: Unplug your dryer.
Always disconnect the power before inspecting or cleaning any parts.

Step 2: Clean the lint filter.
Remove all lint and debris from the filter — even small blockages can trigger the E3 code.

Step 3: Inspect and clean the vent hose.
Pull the dryer away from the wall and make sure the vent hose is not bent or clogged. Use a vacuum to remove any lint buildup.

Step 4: Let the dryer cool down.
Wait at least 30 minutes before restarting it. Overheating may trigger a temporary safety shutdown.

Step 5: Restart the dryer.
Plug it back in and run a short cycle to see if the error disappears.

If the E3 code returns, the thermistor or control board may need professional inspection and replacement.

Preventing Future Dryer Errors
• Clean the lint filter after every load.
• Inspect the vent hose every few months.
• Avoid overloading the dryer.
• Schedule annual maintenance to keep the airflow system clear and safe.
