Samsung Dryer Error Code hE

Samsung dryer hE error explained

The hE code on a Samsung dryer indicates a problem in the heating circuit or heater control. It usually appears when the dryer detects that the heater is not operating within expected parameters, which could be due to a failed heating element, a blown thermal fuse or thermostat, a faulty temperature sensor (thermistor), a damaged heater relay on the control board, or wiring/connection issues. When the hE code appears users commonly experience no heat or intermittent heating, longer drying times, damp clothes at the end of a cycle, and in some cases the dryer may shut down or refuse to start heating as a safety precaution. Because heating issues can increase the risk of overheating or cause stress to electrical components, addressing an hE fault promptly is important for performance and safety.

Common causes

• Failed heating element or open circuit in the heater coil
• Blown thermal fuse or high-limit thermostat
• Faulty thermistor or temperature sensor giving incorrect readings
• Defective main control board or heater relay
• Damaged or loose wiring and connectors in the heater circuit
• Restricted venting causing overheating and safety shutdown
• Moisture or corrosion on terminals and connectors
• Faulty door switch or interlock that prevents heating in some models

Troubleshooting steps

1. Power cycle and clear: unplug the dryer or switch off the breaker for 5 minutes, then power back on. Some temporary faults clear with a reset.
2. Check vents and lint screen: remove lint from the filter and inspect the dryer vent and exhaust hose for blockages. Restricted airflow can trigger safety logic and is an easy fix.
3. Run diagnostics: if your model supports Samsung diagnostic or Smart Check, run the built-in diagnostic to confirm the hE fault and capture related codes.
4. Inspect for visible damage: unplug the dryer and inspect wiring, connectors, and heater assembly for burns, breaks, or loose terminals.
5. Test thermal fuse and thermostats: with power disconnected, use a multimeter to check continuity of the thermal fuse and limit thermostats. An open thermal fuse will prevent heating and often shows as hE.
6. Test the heating element: check the heater coil for continuity and inspect for obvious breaks or grounding to the housing. Replace if open or shorted to chassis.
7. Check the thermistor/temperature sensor: verify the sensor reads within expected values per the service manual or compare resistance at room temperature to spec. Replace if out of range or intermittent.
8. Inspect the control board and relay: if all heater components test good, the main control board or its heater relay may be defective. Look for burn marks or swollen components and consider bench testing or replacement.
9. Verify wiring harness continuity: check continuity between control board connectors and heater components to find broken or intermittent wiring.
10. Test with a heat-only cycle: after repairs, run a short timed cycle to confirm the dryer heats correctly and that the hE code does not return.

Maintenance / Prevention Tips

• Clean the lint screen before every load to maximize airflow.
• Inspect and clean the dryer vent and exhaust duct at least every 6 to 12 months; more often for heavy use.
• Use rigid or semi-rigid metal ducting instead of flexible foil or plastic to reduce lint traps and improve airflow.
• Replace any kinked, crushed, or damaged vent hoses immediately.
• Keep the dryer area and rear panel free from lint buildup and dust.
• Do not overload the dryer; overloading increases drying time and stresses the heater system.
• Ensure the dryer is installed in a well-ventilated area with adequate clearance around it.
• Check and tighten electrical connections periodically (power off first).
• Have the venting professionally cleaned annually if you use the dryer heavily or have long ducts.
• Use recommended dryer cycles and avoid prolonged high-heat cycles for delicate loads.
• Replace worn or frayed wiring and connectors as soon as they are noticed.
• Inspect seals and door closures to ensure the dryer reaches and holds temperature properly.
• Monitor drying performance and address longer-than-usual cycles promptly — they often precede heater faults.
• Keep a working smoke detector in the laundry area as a safety precaution.
• Follow manufacturer service intervals and recalls for your specific model.

FAQ

Conclusion and safety notice

The Samsung dryer hE error most often points to a heating circuit problem that should be addressed promptly to restore performance and reduce safety risk. Always disconnect power before inspecting or testing electrical components. If troubleshooting steps do not resolve the issue or if the repair requires replacing the control board or performing complex electrical work, contact a licensed appliance technician. Prioritize safe repairs and professional help for any doubt about the diagnosis or repair process.
