Samsung Dryer FC Error Code

Invalid power source frequency error

Applies to: All digital display dryers. May also appear as FE, 1 FC.

What's going on

The FC code on a Samsung dryer means the dryer sensed that the electrical power coming in does not match the frequency it expects. Sometimes this is a brief glitch from your home's power, and a reset clears it. If the code keeps coming back, the main control board may need service from a qualified appliance technician.

Household power in the US switches back and forth at a steady rate, called the frequency. Your dryer's main control board checks this incoming power when it starts up and while it runs. If the signal looks wrong or unstable, the board shows FC and stops the dryer to protect itself.

This code applies to Samsung dryers with a digital display. Codes can differ between model generations, so confirm the meaning using your model number, found on the label inside the door or on the back.

Because this code involves the power supply, treat it as an electrical issue. Unplug the dryer or switch off its breaker before you touch anything beyond the control panel buttons.

Likely causes

main control board — The main control board reads the incoming power and decides whether it is valid. If the board is faulty, it can misread normal power and show FC even when your home's electricity is fine.

The same code can mean different things on different model generations. Check the model number on your dryer's rating plate before ordering parts.

Can you fix it yourself?

Hard to do yourself. Most people end up calling a technician.

Safe things to check first

Reset the dryer: unplug it or switch off its breaker, wait a few minutes, then restore power and try a cycle.
Make sure the dryer is plugged straight into its own wall outlet, not into an extension cord, adapter, or power strip.
Check whether other appliances or lights flickered or lost power around the same time, which can point to a household power issue.
If you use a generator or backup power, switch back to regular utility power and see if the code clears.

When to call a technician

If FC returns after a reset while the dryer is on normal household power, call a qualified appliance technician to check the main control board and power supply. Do not open panels or test wiring yourself.
