If a Samsung dryer shows **1 HC**, the verified Samsung meaning in this research set is **heating / over-temperature error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **1 HC**. Search normalization stores it as **1HC** while preserving the characters a homeowner actually sees.

Quick answer
Heating / over-temperature error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 1HC 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
If a Samsung dryer shows **1 HC**, the verified Samsung meaning in this research set is **heating / over-temperature error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **1 HC**. Search normalization stores it as **1HC** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
A symptom that fits 1 HC is that heating can be weak, absent, excessive, or stop unexpectedly.
The 1 HC display becomes more meaningful if the appliance can pause when the control detects an unsafe or implausible temperature condition.
One clue that supports the 1 HC diagnosis is that drying, washing, cooking, or defrost performance can change depending on the appliance.
One clue that supports the 1 HC diagnosis is that 1 HC appears and drying may pause or performance may change because of heating / over-temperature error.
Depending on the exact model, heat, airflow, motor, drainage, door, or sensor behavior can be affected depending on the code family.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Before requesting service for 1 HC, confirm the selected cycle or cooking mode is supposed to use heat.
The next non-invasive check is to check airflow, vents, filters, water supply, or door closure when those conditions affect temperature.
To rule out an accessible cause, allow the appliance to cool before any owner-accessible inspection.
To rule out an accessible cause, do not open energized high-voltage or heating sections.
Before opening any service area, record the code and whether the dryer is vented or heat-pump/ventless.
A safe owner-level check is to clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
Important safety warning. When working around a dryer that shows 1 HC, 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
A returning heating/over-temperature code after external checks requires model-specific testing of sensors, heaters/ignition, relays, wiring, airflow, or control electronics. If 1 HC keeps returning, record the stage at which it reappears so the technician can test the heating / over-temperature error path instead of replacing parts by guesswork.

Resetting can clear a temporary state, not a persistent issue. If **1 HC** comes back, preserve the code and move to the safe checks or model-specific service path.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **1 HC**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
No. **1 HC** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
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 1 HC** separate from same-looking codes used by other Samsung appliance families.
