Samsung Dryer hC error code
The dryer detected abnormal heating - it is getting too hot or the heating temperature reading is invalid. It stops the cycle to prevent overheating.
Also shown as: hC, HC, HE, hE
Last updated: October 6, 2026
What causes the hC error?
- Clogged lint filter restricting airflow
- Blocked or crushed exhaust vent
- Failed thermistor (temperature sensor)
- Failed heating element
- Failed high-limit thermostat or thermal fuse
- Failed main control board
How to fix Samsung hC — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Clean the lint filter thoroughly
Pull the lint filter and remove all lint by hand, then rinse it under warm water if fabric-softener residue remains. A clogged filter is the single most common cause of hC. - Check the exhaust vent for blockages
Inspect the vent hose behind the dryer for kinks, crushing, or lint packing, and check the outside vent hood for obstructions. Restricted airflow traps heat inside the dryer.Safety warning: Unplug the dryer before pulling it out to inspect the vent. - Let the dryer cool down, then reset
Unplug the dryer for 20 to 30 minutes so the overheated components cool, then plug it back in and try a cycle. Heat-triggered faults often need a full cool-down to clear. - Run the vent blockage test
On many Samsung dryers you can run a vent test: with the drum empty and cool, press Power, then hold the two test buttons until Ins appears and press Start. A Clg/C80/C90 result means the vent is blocked.
When to call a technician
- hC returns after cleaning the filter and vent
- The dryer has no heat at all or overheats repeatedly
- The thermistor, heater, or thermal fuse needs testing
- You smell burning or see scorch marks
Frequently asked questions
Is hC dangerous?
It is a warning worth respecting. Overheating dryers are a fire risk, which is why the dryer shuts down. Clean the filter and vent before running it again.
I cleaned everything and hC is still there. Now what?
The thermistor, heating element, thermal fuse, or control board is likely faulty. Those are inside the machine and need a technician with a multimeter.
What is the difference between hC and tS?
hC means the dryer is overheating or the heat reading is invalid. tS means the temperature sensor itself is shorted. Both stop heating, but the root cause differs.
