hC1
Samsung Dryer
Severity: CriticalWhat Does This Error Mean?
The hC1 error means your Samsung dryer has detected excessive heat inside the drum. It is a more specific version of the hC (heat error) code and indicates the temperature sensor detected a critical overheat event. The dryer shuts down to prevent damage or fire.
Affected Models
- DVE50R8500V
- DVE45R6100W
- DVG55M9600V
- DVE52M8650V
- Select Samsung electric and gas dryers
Common Causes
- The dryer vent is clogged, trapping hot air inside the drum
- The thermistor (temperature sensor) has failed and is sending incorrect readings
- The heating element is not cycling off properly, causing continuous heat buildup
- The dryer is in a room with very high ambient temperature or poor ventilation
- Lint buildup inside the dryer cabinet near the heating element
How to Fix It
-
Turn off and unplug the dryer. Let it cool for at least 30 minutes.
Never try to restart an overheated dryer immediately. Let all components cool down first.
-
Remove and clean the lint trap completely.
Even a partially blocked lint screen reduces airflow enough to cause overheating.
-
Disconnect the vent hose from the back of the dryer and clean it end to end.
A dryer vent brush kit makes this easy. Look for lint clumps and remove them fully.
-
Check the vent run length and number of bends.
If the vent hose is longer than 25 feet or has more than two 90-degree bends, airflow is restricted. Shorten the run if possible.
-
Plug in and restart the dryer. If hC1 returns, schedule a repair.
Recurring hC1 after vent cleaning means a faulty thermistor or heating element — both need professional diagnosis.
When to Call a Professional
If cleaning the vent does not resolve hC1, the thermistor or heating element is likely at fault. A technician can test these components with a multimeter. Repair typically costs $150–$300 depending on the part. Do not continue running the dryer — repeated overheating can damage the control board.
Frequently Asked Questions
What is the difference between hC and hC1 on a Samsung dryer?
Both codes indicate overheating. HC1 is a more specific version that points to the temperature sensor detecting a critical heat level. The fixes are the same — start with vent cleaning. If hC1 persists, the thermistor is the more likely culprit than with a plain hC code.
Where is the thermistor located on a Samsung dryer?
The thermistor (temperature sensor) is usually mounted on the exhaust duct inside the dryer cabinet. Accessing it requires removing the back or front panel of the dryer. It's a small sensor with two wire leads. A technician can test it in minutes with a multimeter.
Can I still use the dryer if it shows hC1 occasionally?
No — do not ignore hC1, even if it only shows up sometimes. Overheating is a fire hazard. A dryer that overheats occasionally will overheat badly eventually. Fix the root cause before using it again.
