Also shown as: hC2, HC2

Last updated: October 6, 2026

Quick answer: Samsung dryer error code hC2: gas ignition system fault. The most common cause is gas supply valve to the dryer is closed. Try this first — check the gas supply valve. If that does not clear it, confirm gas is reaching the house.

What causes the hC2 error?

  • Gas supply valve to the dryer is closed
  • Failed igniter
  • Failed gas valve coils
  • Failed flame sensor
  • Loose or damaged ignition wiring
  • Failed electronic control board

How to fix Samsung hC2 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Check the gas supply valve
    Make sure the gas shut-off valve behind the dryer is fully open (handle parallel to the pipe). A valve bumped closed during cleaning is a common cause.
    Safety warning: If you smell gas, do not touch anything electrical - leave the house and call your gas company.
  2. Confirm gas is reaching the house
    Check whether other gas appliances (stove, water heater) work. If none have gas, the problem is the supply, not the dryer - call your gas supplier.
  3. Power-cycle the dryer
    Unplug the dryer for 2 minutes, plug it back in, and try a heated cycle. This resets the ignition control before you assume a parts failure.
  4. Clean the lint filter and vent
    Severe airflow restriction can prevent proper burner operation. Clean the filter and check the vent hose for blockages, then retry.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • hC2 returns with the gas supply confirmed on
  • The igniter, gas valve coils, or flame sensor needs testing
  • The electronic control board is suspect
  • Any smell of gas - leave and call the gas company first

Frequently asked questions

My gas dryer tumbles but there is no heat and hC2 shows. What failed?

The ignition sequence - the igniter, gas valve coils, or flame sensor is not doing its job, so the burner never lights. Gas-side parts are technician-only.

Can I fix the igniter myself?

No. Gas ignition work involves the gas line and high-voltage ignition parts. That is strictly professional work.

Is hC2 the same as hC?

No. hC is a general overheating/heating fault. hC2 is specific to gas models and means the gas burner failed to ignite.
