FC
Samsung FC on a dryer: invalid power source frequency
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On a Samsung dryer, FC or FE means the frequency of the power supply is invalid. Samsung says to restart the cycle; if the code stays, contact a Samsung service centre.
Safety first
Stop and check this first
- Do not open the dryer or the plug to take measurements: with FC the issue is the mains supply and any measuring is a job for an electrician.
Safe checks you can perform
- Exact code
- Restarting the cycle
- How the dryer is plugged in
- Measuring the supply at the socket
Leave these tasks to a qualified professional
- Do not attempt this professional task: Supply check by an electrician

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Supply check by an electrician
What they doThe electrician measures voltage and frequency at the dryer socket and checks the circuit that feeds it.
They must show youthe values measured at the socket.
In writingthe values, the instrument used and the conclusion about the installation.
Dryer electronics diagnosis
What they doIf the supply is correct, the Samsung technician checks the power input and the dryer control board using the service documentation.
They must show youthe check carried out and the part or connection at fault.
In writingthe cause, the part number replaced and the reason.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Exact code
- Who:
- you, no tools.
- How:
- photograph the display and check whether it reads FC, FE or 1 FC. Note the model from the label.
- Result that matters:
- confirming it is the frequency warning.
- If it is FC, FE or 1 FC:
- go on to restarting the cycle.
- If it is another code:
- look it up, because Samsung gives each one different steps.
- Evidence to keep:
- photo of the display and the label.

Restarting the cycle
- Who:
- you.
- How:
- stop the dryer, start the cycle again and watch whether the code reappears.
- Result that matters:
- whether the warning was a passing one.
- If the cycle runs without FC:
- it was a one-off disturbance; note the date and time.
- If FC returns:
- the warning persists; check how it is plugged in and contact the service centre.
- Evidence to keep:
- time of the restart and the result.

How the dryer is plugged in
- Who:
- you, looking without touching the wiring.
- How:
- check whether it is plugged straight into the wall or through an extension lead or power strip, and whether other appliances fail or switch off at the same time.
- Result that matters:
- useful details for the technician without opening anything.
- If it runs on an extension or power strip, or other appliances fail:
- tell the service centre and an electrician.
- If it is plugged straight in and nothing else fails:
- the warning points to the dryer or the grid; contact Samsung.
- Evidence to keep:
- photo of the connection and a note of other affected appliances.

Measuring the supply at the socket
- Who:
- a qualified electrician.
- How:
- measure voltage and frequency at the dryer socket with a suitable instrument.
- Result that matters:
- whether the supply reaching the dryer is correct.
- If it is correct:
- the fault is in the dryer; Samsung service.
- If it is not:
- the repair belongs to the electrical installation, not the dryer.
- Evidence to keep:
- measured values in writing.
Measuring at the socket means mains voltage: only an electrician with a suitable instrument. Do not open sockets or measure yourself.

What it means
Samsung UK and Samsung Canada group FC, FE and 1 FC as a power source frequency problem: the dryer electronics consider that the supply it receives does not have a valid frequency. The official routine is to restart the cycle and, if the code continues, call the service centre. The frequency comes from the grid, but the warning can also come from how the dryer itself measures it. FC does not prove your home wiring is at fault or that the board has failed.
