How to Fix Samsung Dryer Error Code HE

The Samsung “HE” error code (sometimes displayed as “HE2” or “HE3” on certain models) indicates a heating element problem with the dryer. Specifically, this code appears when:

• The dryer isn’t heating properly
• The temperature sensor detects abnormal heating patterns
• The heating circuit experiences electrical issues
• Temperature regulation components malfunction

Unlike some vague error codes, HE directly points to the heating system, which narrows down potential causes and simplifies troubleshooting.

This guide walks you through understanding what the HE error means, identifying the underlying causes, and implementing effective solutions to get your Samsung dryer working properly again.

Samsung Dryer HE Error Code: Causes & Solutions

Let’s examine the most frequent culprits behind this heating error and how to address each one.

1. Clogged Vent System or Poor Airflow

Restricted airflow often triggers the HE error. When exhaust can’t properly exit the dryer, heat accumulates inside, causing sensors to detect abnormal temperatures.

To resolve vent system issues:

1. Disconnect power from the dryer for safety.
2. Pull the dryer away from the wall to access the vent.
3. Detach the vent from the dryer and inspect for visible blockages.
4. Use a vent cleaning kit to remove lint buildup throughout the entire duct.
5. Check the exterior vent hood, ensuring it opens freely and isn’t obstructed.
6. Clean the lint screen thoroughly, washing it with warm, soapy water if needed to remove fabric softener residue.
7. Inspect the internal ductwork behind the lint screen for accumulated debris.
8. Ensure proper vent configuration: rigid metal ducts are preferred over flexible ones, with minimal bends.
9. Verify the total vent length doesn’t exceed Samsung’s recommendations (typically under 35 feet).
10. Reconnect the vent, restore power, and run a test cycle.

Poor ventilation stands out as the most common cause of the HE error, so thorough vent cleaning often resolves the issue immediately.

2. Faulty Heating Element

The heating element generates the heat necessary for drying clothes. When this component fails or develops an electrical break, the HE error frequently appears.

To check and replace the heating element:

1. Disconnect the dryer from power.
2. Access the heating element, typically located at the back of the dryer (refer to your model’s manual for specific location).
3. Inspect the heating element for visible damage like breaks, burns, or blistering.
4. Use a multimeter to test for continuity across the heating element terminals.
5. If continuity is absent or the element shows clear damage, it requires replacement.
6. Purchase a replacement heating element specifically designed for your Samsung model.
7. Disconnect the wiring from the old element and remove any mounting brackets or screws.
8. Install the new heating element, ensuring all connections are secure.
9. Reassemble the dryer panels and restore power.
10. Run a test cycle to verify the error has been resolved.

When replacing the heating element, take photographs before disconnecting components to help with reassembly.

3. Defective Thermistor or Temperature Sensor

The thermistor monitors temperature inside the dryer and communicates with the control board. When it fails, the dryer cannot accurately regulate heat, triggering the HE error.

To inspect and replace the thermistor:

1. Unplug the dryer.
2. Locate the thermistor, usually positioned near the heating element or on the blower housing.
3. Check the thermistor and its wiring for physical damage.
4. Test the thermistor’s resistance with a multimeter; a working thermistor shows variable resistance that changes with temperature.
5. If testing reveals inconsistent readings, purchase a replacement thermistor for your specific model.
6. Disconnect the thermistor wiring harness and remove any mounting hardware.
7. Install the new thermistor, ensuring proper positioning.
8. Reconnect the wiring and reassemble the dryer components.
9. Restore power and test the dryer.

The thermistor is relatively inexpensive and straightforward to replace, making it a cost-effective repair option.

4. Tripped Thermal Fuse or Thermostat

Safety components like thermal fuses and thermostats prevent the dryer from overheating. When these devices trip or fail, they interrupt the heating circuit and can trigger the HE error.

To check these safety components:

1. Disconnect the dryer from power.
2. Access the thermal fuse, typically located on the heating element housing or exhaust duct.
3. Test the thermal fuse for continuity with a multimeter; a blown fuse shows no continuity.
4. Similarly, locate and test the cycling thermostat and high-limit thermostat (refer to your model’s manual for positions).
5. Replace any component that fails the continuity test.
6. When installing new thermal fuses or thermostats, ensure they have identical temperature ratings as the original parts.
7. Secure all connections properly during reassembly.
8. Before restoring power, thoroughly clean the vent system as described earlier, as overheating often causes these components to trip.

Remember that thermal fuses are one-time safety devices—they don’t reset and must be replaced when blown.

5. Control Board Malfunction

Though less common, the electronic control board can occasionally misinterpret signals from temperature sensors or develop circuit problems that generate the HE error.

To troubleshoot the control board:

1. Disconnect power to the dryer.
2. Reset the control board by unplugging the dryer for 5 minutes.
3. After reconnecting power, check if the error persists.
4. If resetting doesn’t work, access the control board (usually behind the control panel).
5. Inspect for visible damage like burned spots, bulging capacitors, or corrosion.
6. Check all wire connections to ensure they’re secure.
7. If other solutions haven’t resolved the issue and you see damage, the control board may need replacement.
8. Due to the complexity and cost, consider professional diagnosis before replacing the control board.

Control board replacement typically requires more technical skill than other repairs, so proceed cautiously.

Summary

The Samsung dryer HE error mainly indicates heating problems caused by restricted airflow, component failures, or electrical issues.

Generally speaking, it’s relatively simple to resolve, but always prioritize safety by disconnecting power before attempting any inspection or repair.

If troubleshooting steps don’t resolve the issue, or if you’re uncomfortable performing technical repairs, calling in an appliance repair technician is recommended.
