Samsung Dryer Error Code hE2

Samsung Dryer hE2 Error — What It Means

The Samsung dryer hE2 error typically signals a heating or temperature-sensing problem: the dryer is detecting abnormal temperature readings or a failure in the heating circuit and has entered a protective fault state. This can be triggered by a defective temperature sensor (thermistor), thermal fuse/thermostat, a damaged heating element or its relay, wiring faults, or even poor venting that causes overheating. When hE2 occurs users commonly experience longer drying times, loads that remain damp, overheating shutdowns, error lights on the control panel, or the dryer refusing to start heating at all. Because heating system faults can create fire and safety risks, it’s important to troubleshoot carefully and stop using the dryer until the root cause is addressed.

Common Causes

• Faulty temperature sensor / thermistor providing incorrect readings
• Open or shorted thermal fuse / cut-out (safety thermostat)
• Defective heating element or heating relay on the control board
• Malfunctioning main control board or heater relay
• Damaged or loose wiring / connectors in the heating circuit
• Blocked or restricted venting / lint buildup causing overheating
• Faulty moisture sensor causing incorrect cycle behavior
• Intermittent door switch or user-interface errors reporting false codes

Troubleshooting Steps

1. Safety first: Unplug the dryer or switch off its breaker before any inspection. For gas models also turn the gas supply off when doing internal checks.
2. Clear vents and lint: Inspect and clean the lint trap, vent hose, and exterior vent hood. Restricted airflow can cause overheating and false heating faults.
3. Reset the dryer: Disconnect power for 1–5 minutes, then reconnect to clear transient errors and see if the code returns.
4. Check error history: Some Samsung models store fault history—consult the user manual for diagnostic mode to confirm hE2 and related codes.
5. Inspect wiring and connectors: Look for burnt connectors, loose pins, or broken wires around the heating element, thermistor, thermal fuse, and control board.
6. Test the thermistor (temperature sensor): Locate and test with a multimeter for expected resistance values (consult model specs). Replace if out of range or intermittent.
7. Test the thermal fuse / thermostat: Check continuity with a meter. An open thermal fuse indicates it has blown and must be replaced.
8. Check the heating element: Measure continuity and inspect visually for breaks or burn marks. Replace a failed element or shorted coil.
9. Inspect the control board and relays: If heating components test OK, the main board or its heater relay may be faulty—look for burnt components or swollen capacitors.
10. Run a controlled test: After repairs, run an empty timed-dry cycle to confirm stable operation and that the hE2 error does not reappear.
11. When in doubt, call a pro: If you’re uncomfortable working with high-voltage components or gas connections, stop and contact an authorized Samsung technician.

Maintenance / Prevention Tips

• Clean the lint filter before every load to maintain airflow.
• Vacuum lint from the dryer cabinet interior and lint trap housing every few months.
• Inspect and clean the vent hose and exterior vent at least twice a year.
• Use rigid or semi-rigid metal ducting for long runs to reduce lint buildup.
• Keep the exterior vent flap clear of debris, birds’ nests, or snow.
• Avoid overloading the dryer; large or wet loads strain the heater and motor.
• Use recommended cycle settings and avoid excessive high-heat cycles when not needed.
• Replace a cracked or kinked vent hose immediately to ensure proper airflow.
• Confirm the dryer is installed with adequate clearance for ventilation.
• Periodically check wiring and connections for discoloration or looseness (power off).
• Test the door switch and seals; a poor door connection can cause abnormal cycles.
• Schedule annual professional maintenance for commercial or heavy-use dryers.
• Install a lint trap or secondary screen on the vent line if your laundry area produces lots of lint.
• Use the appropriate dryer sheets or detergents as recommended—excess residue can build up on sensors.
• Keep the dryer in a well-ventilated area and avoid enclosing it tightly in cupboards without ventilation.
• Replace aging thermal fuses and thermostats proactively if the dryer is older and showing heat inconsistencies.
• Document error frequency—intermittent issues often point to wiring or control-board faults rather than sensors alone.

Frequently Asked Questions (FAQs)

Q: What exactly does hE2 mean on my Samsung dryer?

A: hE2 is a heating-related fault indicating that the dryer has detected an issue with temperature sensing or the heating circuit. The exact meaning can vary by model, but it commonly points to a thermistor, thermal fuse, heating element, or control board problem.

Q: Can I keep using the dryer if it shows hE2?

A: It’s not recommended. Continuing to use the dryer with a heating fault risks poor drying performance and could create overheating hazards. Stop use until you identify the cause or have a technician inspect it.

Q: How much will a repair cost?

A: Costs depend on the failed component and labor rates. Replacing a thermal fuse or thermistor is relatively inexpensive, while a control board or heating element replacement can be more costly. Get a diagnostic quote from a certified technician for an accurate estimate.

Q: Is this something I can fix myself?

A: If you’re comfortable with basic electrical testing, you can clean vents and check continuity on fuses, sensors, and elements. However, do not attempt to repair high-voltage components or gas connections unless you are qualified—call a professional for those repairs.

Conclusion / Safety Notice

Heating-related faults such as hE2 should be treated seriously. Because the dryer heating system works with high temperatures and potentially hazardous voltages (and gas in gas models), always disconnect power before opening the cabinet. If you encounter burned wires, a failed control board, or an uncertain diagnostic, stop and contact a certified Samsung service technician. Ignoring heating faults increases the risk of fire or further damage to the appliance.

If you’re comfortable performing the non-electrical checks (cleaning lint, clearing venting) and basic continuity tests, proceed carefully. For anything involving the heating element, relays, control board, or gas components, schedule a professional repair to ensure safe, correct service and preserve any warranty coverage.
