Samsung dryer FC: Power frequency is invalid

THE SHORT ANSWER

Power frequency is invalid.

FC reports a power-source frequency problem. Restart the cycle once as directed; continued FC needs support.

First safe check

Record whether the dryer was installed in a different country from where it was sold.

Applies to

Samsung dryer families covered by the cited US guidance. Match the full model number and exact display; this is not an exact-model compatibility claim.

Before you start

Do not bypass the door switch, run with disconnected exhaust, or open electrical or gas components. Stop for smoke, scorching, or a gas odor.

WHAT YOU MAY NOTICE

Symptoms to record

  • The dryer displays FC.

WORK THROUGH THE BASICS

Safe troubleshooting checks

0 of 2 checked

Use the checkboxes to keep track as you read. Stop at any warning or step that does not match your appliance.

  1. Use the normal controls to restart the interrupted program.

    What to note

    The frequency warning either clears or repeats.

  2. If FC returns, provide the model and installation location to Samsung; let a qualified person assess supply compatibility.

    What to note

    No live electrical measurement is attempted by the owner.

THE DETAILS MATTER

Scope & troubleshooting notes

How to interpret this result

Frequency is different from voltage. A plug adapter does not establish electrical compatibility, and this code is not a reason to change the dryer’s wiring yourself.

YOUR NEXT DECISION

When to stop and get help

Arrange Samsung service if the condition remains after the listed owner checks, or if damage prevents completing them safely.

Record what you see

Keep the full model number, exact displayed code, and your observations together for the next conversation.

Use the right support

Contact the manufacturer or a qualified appliance technician when the guide calls for service.
