How to fix the HC error code in a Samsung dryer?

Error codes such as HC, HE, HC4, 1 HC, etc. all indicate that your dryer is overheating. The most common reason for this error code is a clogged exhaust vent, lint screen, or both.

If your dryer displays an error code related to an overheating issue, the first step is to turn off the dryer and let it cool down before you begin troubleshooting.

In the meantime, you can look in the owner’s manual for your dryer to find the error code and possible reasons for it.

Key Takeaways

  • If your Samsung dryer is overheating, this can be caused by a number of things, but the most common cause is restricted airflow.
  • Other things like overloading, a broken temperature sensor, a damaged heating element, etc. can also contribute to overheating.
  • Overloading and overusing the dryer can also cause an HC error code.
  • Turn off the dryer when you see the HC error code and let it cool before inspecting.

Safety Disclaimer

Please note that working with appliances, such, as your Samsung dryer can be hazardous. If you are uncertain or uncomfortable with performing repairs it is always advisable to seek assistance, from a certified technician. Remember to disconnect the dryer from the power source before attempting any repairs.

Why does a dryer overheat?

The major causes of an overheating dryer are clogging of the lint screen or vent, overloading, overusing, faulty sensors, or even a problematic heating element.

Out of all the technical faults, there are a few things that are controllable, such as clogs, overuse, and overloading the dryer.

Furthermore, timely maintenance of your dryer will prevent it from clogging.

How to fix the HC error code in a Samsung dryer?

Apart from the hC error code, there are a few other codes in Samsung dryers that point toward overheating problems such as hE, HC4, 1 HC, etc.

Here are some common causes for the hC error, along with some possible solutions.


The first step is to determine if you have overused your dryer more than usual.

If that is the case, then simply turn off the dryer and let it rest for some time, or use it after a gap of an hour or two.

Note: If that fixes the problem, then simply avoid overusing the dryer, as it can lead to mishaps due to overheating.


If you have loaded a lot of garments, which is beyond the dryer’s capacity, then that could be the possible reason for overheating.

Simply turn off the dryer, and as it cools down, remove a few garments from the drum.

Try running the dryer, and this should fix the error.

Drying Large Sheets

In some cases, if you have loaded a large garment or a king-size bedsheet with no room left in the drum.

This will prevent the required airflow into the drum and lead to overheating.

Lint Screen

If your dryer is overheating, it’s time to check the lint filter to see if it needs to be cleaned.

Depending on the dryer type you can locate and remove the lint screen along with its mounting bracket.

Clean it thoroughly and reinstall it back to check if the problem still persists.

If the filter is clean or if the error still appears after performing all the cleaning tasks, then the next step is to inspect the venting system.

Clogged Vent

One of the other common reasons for overheating could be that the air vents are blocked.

The vents allow hot air to escape from the dryer, and if they are blocked, the hot air has nowhere to go.

This can cause the dryer to overheat and in the worst cases, it can lead to even catching fire.

Hence it is always advised to clean the air vents regularly.

Moreover, you should inspect them once a month to ensure they are clear and unobstructed.

If the venting system is clear and the dryer still shoots the same error code, then the next step is to proceed toward the technical parts.

Power Surges

If you have noticed a power fluctuation issue in your household recently and if the dryer was running at the same time, it could be the possible cause of why the dryer is overheating.

Simply halt the dryer mid-cycle and unplug it from power.

Then, run the dryer only after the power supply stabilizes.

Running a dryer or any other appliance during power surges can lead to damage to the unit, especially the electrical components.

Check the Wires

Start by unplugging the wire from the power socket and seeing if it shows any signs of wear and tear.

If the power cables are worn out, replace them, and if they’re in a good condition, try switching the socket.

Problematic Gas Supply

If your Samsung dryer has a problematic gas supply, it can lead to overheating.

Check to see if there is any loose connectivity and if there is, fix it.

If the clamps are not in the right position, they will not make a proper connection, and this can result in a gas leak.

A gas leak can have severe consequences, so it is always better to get it checked by a professional.

Faulty Thermostat

A faulty thermostat is one of the most common reasons for an error code like hC.

A thermostat is responsible for maintaining the temperature in the dryer.

It senses when the dryer has reached the set temperature and then turns off the heating element.

If the thermostat is not functioning properly, it will not be able to sense the temperature correctly, which will result in the dryer overheating.

You can check the thermostat with a multimeter to see if it is working correctly or not.

In most cases, the thermostat will need to be replaced if it isn’t working correctly.

Contact Service professionals

When nothing works out, or when the situation is not under your control, and if you feel it is related to technical aspects, then simply contact a service professional.

When it comes to technical errors, it can be the heating element, sensors, electrical wires, control board, improper voltage, etc. that is causing the dryer to overheat and trigger hC or relevant errors.

Final Thoughts

Most error codes can be fixed on your own, such as by cleaning the required areas, allowing the appliance to rest, or, in some cases, by a simple restart.

For technical issues, you can still try it on your own only if you are familiar with the appliance and have some experience.

If not, then it is always advised to contact a service professional, as they are better equipped to deal with such situations.

Dealing with electrical appliances can be tricky, and a single wrong move can cause irreversible damage to the appliance or even lead to accidents such as fire.

Lastly, regular maintenance, such as cleaning or servicing the dryer, is always a good practice.
