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
- 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.
- 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.
- Reset the dryer: Disconnect power for 1–5 minutes, then reconnect to clear transient errors and see if the code returns.
- Check error history: Some Samsung models store fault history—consult the user manual for diagnostic mode to confirm hE2 and related codes.
- Inspect wiring and connectors: Look for burnt connectors, loose pins, or broken wires around the heating element, thermistor, thermal fuse, and control board.
- 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.
- Test the thermal fuse / thermostat: Check continuity with a meter. An open thermal fuse indicates it has blown and must be replaced.
- Check the heating element: Measure continuity and inspect visually for breaks or burn marks. Replace a failed element or shorted coil.
- Inspect the control board and relays: If heating components test OK, the main
