Samsung Dryer HC2 — What It Means & How to Fix It
HC2 appears on gas Samsung dryers when the burner fails to ignite, so the drum turns but the clothes stay cold — and because every remaining cause is a gas component, this one goes to a licensed technician after a couple of safe checks.
What this code means
On a gas dryer the control expects the burner to light and heat, and HC2 is logged when ignition doesn't happen. The usual culprits are the igniter, the flame sensor, or the gas-valve solenoid coils — all part of the sealed gas burner assembly. That places HC2 firmly outside DIY territory: gas components are not something to test or replace at home.
HC2 is specific to gas models — an electric dryer won't show it. Beyond confirming the gas supply is turned on and giving the dryer one power reset, there's no safe user repair here; the burner assembly must be serviced by a qualified technician.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Failed igniter in the gas burner assembly | Common | No — technician job |
| Faulty flame sensor | Common | No — technician job |
| Defective gas-valve solenoid coils | Occasional | No — technician job |
| Gas supply shut off, or an LP / natural-gas setup mismatch | Occasional | Partly — check supply only |
| Tripped thermal fuse cutting the heat circuit | Occasional | No — technician job |
What you can try yourself
- Turn the dryer off at the breaker or unplug it, wait two to three minutes, and power it back on to rule out a one-time control glitch.
- Check that the gas shutoff valve behind the dryer is fully open and that other gas appliances in the home are working — this only means looking at the valve handle, not touching the gas line or its connections.
- Confirm the dryer is set up for the gas type you have (natural gas versus LP); a mismatch after a move or conversion can stop ignition. Read the rating plate, and leave any conversion to a professional.
- If the burner still won't light, stop here and book a technician — do not attempt to inspect, test, or replace the igniter, flame sensor, or gas valve yourself.
When to call a technician
- The dryer runs but never heats, and HC2 stays after a power reset.
- You smell gas at any point — leave the dryer off, ventilate, and if the smell is strong, leave and call your gas utility from outside.
- The dryer was recently moved, converted, or reconnected to gas.
Typical professional repair cost: Gas dryer ignition repairs — igniter, flame sensor, or gas-valve coils — generally run $150–$350 with labor, depending on which part has failed.
Frequently asked questions
Why is my Samsung gas dryer showing HC2 and not heating?
HC2 means the gas burner isn't igniting, so the drum spins but no heat is produced. The common causes are a failed igniter, flame sensor, or gas-valve coils — all gas-burner parts. After confirming the gas supply is on and doing one power reset, it's a technician repair; these components aren't safe to test or change at home.
Is HC2 dangerous?
The code itself is the dryer safely refusing to run without ignition, which is good. The caution is around the gas system: never try to inspect or repair the burner, valve, or gas line yourself. And if you ever smell gas, leave the dryer off, ventilate, and contact your gas utility — from outside if the smell is strong.
Does HC2 happen on electric Samsung dryers?
No. HC2 is a gas ignition error, so it only appears on gas models. On an electric dryer a heating problem shows up differently — usually as HC (overheating) or a temperature code — and those start with cleaning the lint filter and vent rather than a gas repair.
