Samsung Dryer HC2 Error Code: Causes, Cost & Fix

What is the Samsung Dryer HC2 error?#

The HC2 code is specific to gas Samsung dryers and means the burner failed to ignite — the machine tumbles but produces no heat. Unlike a general overheat code, HC2 is about the gas ignition system: the igniter did not glow hot enough, or the gas valve did not open, so no flame started. The tell-tales are cold, damp clothes at the end of a cycle, sometimes a clicking as the system tries to light, and occasionally a faint smell of unburned gas. If you ever smell strong gas, stop and ventilate — but a faint whiff during a failed light attempt is the system doing its job and shutting off. Power-cycle once to reset a transient lockout.

HC2 on a Samsung Dryer: likely causes and repair cost#

On a Samsung Dryer, the HC2 code signals: gas ignition failure (gas dryers).

Typical professional repair: $175–$350 · Difficulty: professional only · usually a technician job

Symptoms that often accompany HC2: Dryer runs but produces no heat; Dryer heats initially then stops heating; Faint gas smell near the dryer (unburned gas); Clicking sound from the gas valve but no ignition

Technician diagnostic sequence for HC2:

1. Confirm gas supply is on — check the gas shutoff valve behind the dryer (handle should be parallel to the gas line, not perpendicular). Also check the main gas meter valve
2. Access the burner assembly by removing the lower front panel. Start a cycle and observe: the igniter should glow bright orange within 30 seconds. If it does not glow at all, the igniter has failed
3. If the igniter glows but gas does not flow, the gas valve solenoid coils are the problem. Samsung gas dryers use two coils on the gas valve — both must work in sequence. Test each coil for approximately 1.0-1.5 k-ohm resistance
4. If the igniter glows and gas flows but does not ignite, the flame sensor may be misaligned or coated in carbon. Clean the flame sensor and verify its position relative to the burner opening

Parts a technician may check or replace: Samsung DC47-00076A; Samsung DC32-00008B — includes both coils; Samsung DC32-00009B

Field note: Samsung gas dryer valve coils have a characteristic failure pattern: they work when cold but fail after the dryer runs for a few minutes (heat weakens the coil magnetism). If the dryer heats for 10-15 minutes then goes cold while still running, the coils are the problem — not the igniter.

Safety note: Gas dryer repairs involve natural gas or propane lines. If you smell gas or suspect a leak, shut off the gas supply, ventilate the area, and do not operate any electrical switches. Call a licensed professional.

How to troubleshoot the HC2 error yourself#

HC2 leaves very little for an owner to do safely, because it involves the gas train. You can and should confirm the gas supply is on (check that other gas appliances work) and that the dryer is not simply out of gas at the shutoff. Clean the lint filter and vent as general maintenance. Beyond that, the causes in the table above — a failed igniter or gas valve coils — are strictly "professional." Working on gas components carries real risk, and diagnosing which part failed requires testing the igniter and valve safely. This is the dryer code where I firmly tell owners to stop after checking the gas supply and call a technician; do not open the burner assembly yourself.

Is the Samsung Dryer HC2 error worth fixing?#

HC2 is worth repairing on a gas dryer with life left, and the fix is usually a well-defined part swap. The table above lists $175 to $350, typically to replace the igniter or the gas valve coils — a standard repair for a technician. Against buying a new gas dryer that is a small share of the cost, so I fix it in most cases. Only on an old machine with other problems would replacement come up; a standalone HC2 on a sound gas dryer is comfortably worth the $175 to $350. One thing that makes this repair a good value is that the parts involved are common, well-documented service items rather than obscure electronics, so a technician can usually diagnose the failed igniter or valve and carry the replacement on the first visit. That keeps the labor time — and the total bill — near the lower end of the range for most owners.

Samsung Dryer HC2: frequently asked questions#

What does the HC2 error mean on a Samsung Dryer?#

On a gas dryer it means the burner failed to ignite, so the drum turns but there is no heat. A failed igniter or gas valve is the usual cause.

Is it safe to keep using a Samsung Dryer that shows the HC2 error?#

It will simply run cold, which is not hazardous, but if you smell strong gas, stop and ventilate. Otherwise arrange a gas-qualified repair before relying on it.

Can I clear the HC2 error myself, or do I need a technician?#

You can confirm the gas supply is on and power-cycle once, but the igniter and gas valve are a technician job — do not service the burner yourself.

How much does it cost to repair the HC2 error on a Samsung Dryer?#

The table above lists $175 to $350, typically to replace the igniter or gas valve coils.

Which parts usually fail when a dryer throws the HC2 code?#

The igniter or the gas valve coils, as shown in the table above, with the igniter the more common failure.

Why does an igniter failure trigger the HC2 error?#

If the igniter cannot glow hot enough to light the gas, no flame starts; the dryer senses no heat during the ignition window and flags HC2, shutting the gas for safety.
