Samsung Dryer Error Code HC2
On a gas dryer, the burner did not light, so there is no heat and the control stops the cycle. Confirm the gas valve is open and the home's gas supply is live; anything beyond that sits inside the gas train and belongs to a technician.
Common causes
- Gas supply cut-off valve closed or not fully open
- Gas igniter has failed
- Gas valve coils have failed
- Flame sensor fault
What to check, in order
- Make sure the gas cut-off valve for the dryer is fully open, and check that other gas appliances in the home are working.
- Power the dryer off for two to three minutes, then restart a heated cycle once and listen for the burner to light.
- If you smell gas at any point, stop, turn the gas valve off, and call your gas supplier instead of retrying.
- If the code returns, book a technician; the ignition parts on a gas dryer are not a DIY repair.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
This code usually points to a faulty part, wiring or the control board on a Samsung dryer. Run the checks above to rule out the simple causes, then book a technician — and book one straight away if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code HC2, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
Repair or replace?
This fault is in professional territory: the fix usually means a major part or board-level work, and the labour adds up. If your machine is already well into its service life, get the repair quote first, then compare it with the price of a current equivalent model before you decide. Paying a large share of a new machine's price to repair an old one is rarely the better deal; replacing a machine over one cheap fault is wasteful too.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
