Samsung gas dryer HC2 indicates a gas ignition error—the dryer cannot ignite the gas burner. First verify the gas shutoff valve is OPEN (handle parallel to pipe). This is the ONLY officially documented Samsung gas ignition code. Due to gas safety concerns, professional service is recommended for most users.
| Error Code | HC2 |
|---|---|
| Meaning | Gas ignition failure—burner cannot ignite |
| Difficulty | Professional Recommended |
| Time to Fix | 30 min diagnosis, 1-2 hours repair |
| Tools Needed | Multimeter, Screwdriver |
| DIY Fixable | Professional recommended |
| Official Source | Samsung Support |
The HC2 error appears exclusively on Samsung gas dryers (DVG series) when the dryer cannot ignite the gas burner. This is a safety-critical error that requires careful diagnosis.
Important Clarification
HC2 is the ONLY officially documented Samsung gas ignition code. Other codes sometimes mentioned online (gF, nF, Et) were NOT found in Samsung’s official documentation and may be misattributed from other manufacturers.
What HC2 Means
The dryer’s control board detected that gas ignition failed. The drum may turn, but no heat is produced. This could indicate:
- Gas supply is not reaching the burner
- Igniter is not functioning
- Gas valve coils are defective
- Flame sensor is not detecting ignition
Gas Safety Warnings
If you smell gas strongly:
- DO NOT turn on/off any lights or switches
- DO NOT use your phone inside the home
- Leave immediately with everyone
- Call 911 or your gas company from outside
Carbon monoxide risk: Gas dryers produce CO during combustion. A blocked exhaust vent can cause CO to back up into your home. CO is colorless and odorless—install a CO detector near your laundry room.
CO poisoning symptoms: Headache, dizziness, weakness, nausea, confusion, flu-like symptoms without fever.
Safe DIY Troubleshooting
Step 1: Check Gas Shutoff Valve
Locate the gas shutoff valve behind or near your dryer (usually on the flexible supply line within 6 feet of the appliance).
| Valve Position | Status |
|---|---|
| Handle PARALLEL to pipe | Gas is ON (flowing) |
| Handle PERPENDICULAR to pipe | Gas is OFF (stopped) |
Ensure the valve is fully open (parallel).
Step 2: Verify Gas Service
Check if other gas appliances work (stove burners, gas water heater). If nothing works:
- Check if gas bill is paid
- Contact your gas company
Step 3: Clean Exhaust Vent
A severely blocked vent can interfere with ignition:
- Clean lint filter completely
- Disconnect and clean exhaust vent hose
- Brush clean entire duct to exterior
- Check exterior vent flap opens freely
Step 4: Power Reset
- Turn off dryer
- Wait 5-10 minutes
- Turn back on and start a cycle
- Listen for clicking sounds indicating ignition attempts
The gas burner flame should be steady blue. Yellow or flickering flames indicate incomplete combustion and potential CO production—call for service immediately.
Advanced Diagnosis (Requires Caution)
If you’re experienced with gas appliances and can safely access the burner area:
Observing the Ignition Sequence
- Access the burner viewing area (consult your model’s service manual)
- Start a heat cycle
- Watch the igniter
Diagnosis based on igniter behavior:
| Observation | Likely Cause |
|---|---|
| Igniter does NOT glow | Igniter failed—test continuity, replace if open |
| Igniter glows but gas doesn’t ignite | Gas valve solenoid coils defective |
| Igniter glows, dims with click, no gas | Flame sensor may be faulty |
| Everything works but error persists | Control board issue |
Common Failed Components
| Part | Part Number | Cost |
|---|---|---|
| Gas valve assembly | DC62-00201A | $80-150 |
| Igniter | Various by model | $30-60 |
| Flame sensor | Various by model | $20-40 |
| Gas valve coils | Various by model | $20-50 |
When to Call a Professional
Call a technician if:
- You smell gas at any point
- Gas supply is confirmed but igniter doesn’t glow
- Igniter glows but flame doesn’t ignite
- You’re not experienced with gas appliances
- Error returns after basic troubleshooting
Gas valve and igniter replacement should be performed by qualified technicians due to the risks of gas leaks, improper combustion, and carbon monoxide.
