Samsung Dryer Error Code HC — What It Means & How to Fix It

What Does This Error Mean?

Samsung dryer error HC means the temperature inside the dryer drum has gotten dangerously high. The dryer shut itself down as a safety measure to prevent fire or damage. This is a critical error — do not restart the dryer until you find and fix the cause.

Common Causes

The exhaust vent is blocked by lint buildup, restricting airflow and trapping heat inside
The vent hose at the back of the dryer is kinked, crushed, or disconnected
The lint filter was not cleaned before the cycle and is heavily clogged with lint
The dryer is installed too close to a wall, blocking the exhaust vent outlet outside
The heating element or thermistor is faulty and allowing the dryer to overheat beyond the safe temperature range

How to Fix It

Turn off the dryer immediately and unplug it from the wall. Open the dryer door to allow the drum to cool down.

Do not reach into the drum right away — it will be very hot. Wait at least 10 minutes before handling anything inside.
Remove the lint filter from inside the door opening. Clean all visible lint off the filter under running water or with a vacuum. Dry it completely before reinserting.

The lint filter should be cleaned before every single dryer load. A clogged filter is the most common cause of HC.
Go outside and find the dryer exhaust vent opening on the exterior wall of your home. Check that it is not blocked by lint, a bird nest, or a damaged flap.

The exterior vent flap should open freely when the dryer is running. A stuck or blocked flap traps hot air inside.
Pull the dryer away from the wall. Inspect the flexible vent hose connecting the back of the dryer to the wall duct. Check for kinks, crushing, or disconnected sections.

Flexible plastic vent hoses are especially prone to kinking. Consider replacing them with a rigid metal duct for better airflow.
Reconnect everything, plug the dryer back in, and run a short air-dry cycle with no heat. If it runs without HC, proceed to a normal timed dry cycle and monitor.

If HC returns even after clearing all lint and vent blockages, the heating element or thermistor may need professional inspection.

When to Call a Professional

HC is a fire-safety warning that you should take seriously. If cleaning the lint filter and vent does not fix the problem, call a technician. A blocked or damaged vent is a fire hazard — do not continue using the dryer until the airflow is confirmed clear.

Frequently Asked Questions

How often should I clean my dryer vent to prevent error HC?

Clean the lint filter before every single load — this takes about 5 seconds and is very important. The full exhaust vent duct from the dryer to the outside should be cleaned at least once a year. If you dry a lot of laundry, clean the full vent every 6 months.

Can a blocked vent cause a house fire?

Yes. Blocked dryer vents are one of the leading causes of house fires. Lint is highly flammable, and a blocked vent causes heat and lint to build up together. Taking error HC seriously and clearing vents regularly is a genuine fire prevention measure.

My vent is clear but HC keeps coming back. What is wrong?

If the vent is clear and the lint filter is clean but HC keeps occurring, the thermostat or thermistor inside the dryer may be faulty. A faulty thermistor can misread temperatures or fail to regulate heat properly. A Samsung-certified technician can test and replace the thermistor or heating element.
