What to check first
Can I keep using it?
Electrical warning: stop and verify
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.
Dryer heat and airflow warning
Do not keep running a dryer that overheats, smells hot, or has a severe airflow restriction warning.
- Safe next step
- Stop the cycle, let the dryer cool, clean the lint screen, and check only visible vent restrictions before retrying.
- Stop when
- Airflow stays weak, the dryer overheats, the outside vent cannot open, or gas/electrical supply concerns appear.
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.
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.
