The **HC2** display on a Samsung dryer points to **gas ignition error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **HC2**. Search normalization stores it as **HC2** while preserving the characters a homeowner actually sees.

Quick answer
Gas ignition error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so HC2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The **HC2** display on a Samsung dryer points to **gas ignition error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **HC2**. Search normalization stores it as **HC2** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
Depending on the exact model, the appliance can stop or limit the affected function when the code is detected.
Depending on the exact model, the same code can return at a repeatable stage of operation.
On affected Samsung dryer models, other symptoms depend on the model and the subsystem named by Samsung.
Depending on the exact model, hC2 appears and drying can pause or performance may change because of gas ignition error.
While HC2 is active, heat, airflow, motor, drainage, door, or sensor behavior can be affected depending on the code family.
Why it happens
Possible causes
varies by model/region — cross-region baseline — Gas ignition error
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Before opening any service area, record the exact code, model number, and operating stage before resetting power.
Before opening any service area, complete only the owner-accessible checks described in the model manual.
With HC2 recorded, do not replace parts solely from a display code when wiring, conditions, or control feedback can create the same result.
Before opening any service area, record the code and whether the dryer is vented or heat-pump/ventless.
As an external check for HC2, clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
As an external check for HC2, stop repeated resets if the code reappears; model-specific electrical/refrigeration diagnosis may be required.
Important safety warning. When working around a dryer that shows HC2, keep the checks external and non-invasive. Stop for burning smell, smoke, gas odor, repeated breaker trips, or abnormal overheating. Do not bypass thermal protection.

When to request repair service
If the owner-accessible checks do not clear HC2, If the code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
You can try the one reset Samsung documents for the model, but **HC2** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
The code alone is not enough to justify a part. **HC2** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Dryer HC2** separate from same-looking codes used by other Samsung appliance families.
