Samsung Dryer Error Code FC — Frequency Error
What this means
The FC error code indicates the dryer's control board has detected that the incoming electrical frequency is outside the normal 60 Hz range (50 Hz in some regions). This is usually caused by a power supply issue, a faulty control board, or an incompatible power source such as certain generators.
Alternate codes: FE
Step-by-step fix
3 stepsPower cycle the dryer
Unplug the dryer for 10 minutes and plug it back in. A temporary power fluctuation can trigger this code.
Check the power source
If you are running the dryer on a generator, ensure it provides clean, stable 240V at 60 Hz. Cheap or overloaded generators can produce unstable frequency. Test with a multimeter that has a frequency (Hz) measurement function.
Inverter generators produce much cleaner power than conventional generators.
Check for local power issues
If other appliances in your home are also behaving unusually, contact your power utility company. Voltage and frequency irregularities from the grid can cause this error.
A whole-home surge protector can help protect appliances from power anomalies.
When to call a professional
If the power supply is normal and the error persists after a power cycle, the dryer's main control board may be faulty and should be diagnosed by a technician.
