What to check first
Can I keep using it?
Do not keep using the appliance while this warning is active.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Dryer not on its own circuit
- Extension cord use
- Incorrect electric dryer power-cord installation
- Power-grid mismatch after moving a dryer between countries
Basic checks
- Confirm the dryer is on its own circuit.
- Do not use an extension cord.
- For electric dryers, review power-cord installation only at the safe owner-check level.
- Check for a tripped breaker or recent outage; if power symptoms repeat, stop using the dryer.
- Confirm the display is stable after power is restored; if it flickers or drops, avoid another cycle.
- Reset only after power is stable; if the code returns, treat supply or control checks as unresolved.
Reset or retry steps
- Retry only after the power supply setup has been checked.
- If a stacked multi-control setup reports 9C1, check Samsung's SmartThings software-update note.
When to call a technician
- Contact an electrician for voltage or power-cord concerns.
- Request Samsung service if the voltage code continues after safe power checks.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
