What to check first
Can I keep using it?
Do not keep using the appliance while this warning is active.
Do not keep running a dryer that overheats, smells hot, or has a severe airflow restriction warning.
A restricted vent can increase dryer fire risk; stop if there is burning smell, smoke, or repeated overheating. Persistent headaches, dizziness, nausea, or weakness near a gas appliance can be a carbon monoxide warning: leave the area, ventilate only if safe, and call emergency services or qualified service for a CO check.
- Safe next step
- Stop the cycle, let the dryer cool, clean the lint screen, and check only visible vent restrictions before retrying.
- Stop when
- Airflow stays weak, the dryer overheats, the outside vent cannot open, or gas/electrical supply concerns appear.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Clogged lint screen
- Restricted vent system trapping heat
- Low voltage on some electric dryers
Basic checks
- Stop the cycle and let the dryer cool.
- Clean the lint screen.
- Check visible exhaust restrictions before retrying.
- Let the appliance cool before any retry; if the code appears cold, the sensor warning is still active.
- Check for unusual heat or odor from outside the appliance; if present, stop use and keep power off.
Reset or retry steps
- Retry only after lint and vent restrictions are cleared.
- For electric dryers, do not keep retrying if low voltage or supply issues are suspected.
When to call a technician
- Contact an electrician if an electric dryer may have low voltage.
- Request Samsung service if HC or hE continues after lint and vent cleaning.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
