Quick answer
Power-frequency error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so FC 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 **FC**, the verified Samsung meaning in this research set is **power-frequency error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **FC**. Search normalization stores it as **FC** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
The FC display becomes more meaningful if the appliance can stop, restart, or refuse a high-load function.
On affected Samsung dryer models, the code can appear after a surge, brownout, outage, incorrect supply, or frequency problem.
On affected Samsung dryer models, some models preserve the display even when one required power leg or voltage range is abnormal.
The FC display becomes more meaningful if fC appears and drying may pause or performance may change because of power-frequency error.
Depending on the exact model, heat, airflow, motor, drainage, door, or sensor behavior may be affected depending on the code family.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
The next non-invasive check is to confirm the breaker has not tripped and the appliance is connected as specified by Samsung.
With FC recorded, if the event followed an outage or surge, perform only the documented one-time power reset.
With FC recorded, do not perform live mains-voltage measurements unless qualified.
The next non-invasive check is to stop if breakers trip repeatedly, plugs/outlets overheat, or there is arcing.
Before opening any service area, record the code and whether the dryer is vented or heat-pump/ventless.
For FC, start by doing this: clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
Important safety warning. Stop for burning smell, smoke, gas odor, repeated breaker trips, or abnormal overheating. Do not bypass thermal protection. If resolving FC would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
Persistent power/voltage codes need the household supply and appliance power/control circuits checked safely before parts are replaced. If FC keeps returning, record the stage at which it reappears so the technician can test the power-frequency error path instead of replacing parts by guesswork.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **FC** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
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. **FC** 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 FC** separate from same-looking codes used by other Samsung appliance families.
