Samsung Dryer Error HC2: Gas Ignition Error — Gas Dryer Only

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The gas dryer has detected a failure in the gas ignition system. The burner is not lighting correctly or at all, preventing the dryer from generating heat.

Severity

High - stop using the Samsung dryer until the cause is understood or professional help is arranged.

Can you fix it yourself?

No — call a technician

Most likely cause

Gas igniter failed or worn out — igniters have a limited lifespan

Estimated time for safe first checks: Professional service required.

Step-by-Step DIY Fix Guide

  1. SAFETY: If you smell gas, leave the building immediately and call your gas supplier. Do not use electrical switches.
  2. Confirm other gas appliances in the home are working — if not, the gas supply has been interrupted.
  3. Locate the gas supply valve behind the dryer and confirm it is fully open (parallel to the pipe).
  4. Reset by unplugging for 2–3 minutes, then restore power.
  5. If HC2 returns, call Samsung Support at 1-800-726-7864.

If the airflow problem comes back

  • If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
  • Any recurrence after power reset and gas supply confirmation
  • Dryer runs but produces no heat

What This Error Means

Error HC2 on your Samsung dryer means: The gas dryer has detected a failure in the gas ignition system. The burner is not lighting correctly or at all, preventing the dryer from generating heat. The dryer's self-diagnostic system has flagged this condition and may have paused the current cycle.

The most frequent cause is gas igniter failed or worn out — igniters have a limited lifespan. Work through the causes and steps below before calling a technician.

Samsung's official guidance classifies HC2 as a technician-only fault. A 60-second power reset is the only DIY step. If the code returns, contact Samsung Support at 1-800-726-7864.

Gas dryer ignition issues should never be ignored. A failed igniter means the gas valve may still be opening without a flame to ignite the gas. Stop using the dryer and call a technician immediately if you detect any gas smell.

Most Likely Cause by Symptom

The Samsung dryer may stop, pause, or refuse to complete the cycle normally.

Likely cause: Gas igniter failed or worn out — igniters have a limited lifespan

Check first: SAFETY: If you smell gas, leave the building immediately and call your gas supplier. Do not use electrical switches.

Common Causes

  • Gas igniter failed or worn out — igniters have a limited lifespan
  • Gas supply valve not fully open
  • Gas radiant sensor (flame sensor) failed — not detecting when igniter is hot enough
  • Gas valve coils failed — valve is not opening to admit gas
  • Gas supply interrupted — check other gas appliances in the home

What Not to Do

  • Do not attempt to inspect or replace gas components yourself — gas system work requires a licensed technician
  • Do not ignore HC2 on a gas dryer and continue running it — a failed igniter means gas may be flowing without igniting

Model and Display Variation Notes

Model-family notes

  • Samsung dryer display wording and code formats can vary by series.
  • If your model behaves differently, check the owner manual before trying any deeper maintenance step.

Display and panel differences

  • Panel wording can vary by series, so confirm the exact code pattern before buying parts.

Parts, Tools and Service Options

Service option

Samsung service visit if the warning returns after the basic checks are complete.

Manual and model check

Check your exact model and manual before ordering any Samsung dryer parts.

Common parts

  • Gas igniter ($20–$50)
  • Gas valve coil kit ($20–$40)
  • Radiant flame sensor ($15–$35)

This section stays service-first because the page points more strongly toward support or professional repair than a routine parts purchase.

When Not to Keep Troubleshooting

Any recurrence after power reset and gas supply confirmation

  • Dryer runs but produces no heat

How to Prevent It Recurring

  • Have a licensed technician inspect the gas ignition system every 3–5 years — igniters wear gradually and HC2 can be avoided with proactive replacement
