Seeing **9C1** on a Samsung dryer narrows the problem to **voltage / power-supply error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **9C1**. Search normalization stores it as **9C1** while preserving the characters a homeowner actually sees.

Quick answer
Voltage / power-supply error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 9C1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Signs
Symptoms you may notice
Depending on the exact model, the appliance may stop, restart, or refuse a high-load function.
Depending on the exact model, the code can appear after a surge, brownout, outage, incorrect supply, or frequency problem.
While 9C1 is active, some models preserve the display even when one required power leg or voltage range is abnormal.
While 9C1 is active, 9C1 appears and drying may pause or performance may change because of voltage / power-supply error.
On affected Samsung dryer models, heat, airflow, motor, drainage, door, or sensor behavior may be affected depending on the code family.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Before opening any service area, confirm the breaker has not tripped and the appliance is connected as specified by Samsung.
Before opening any service area, if the event followed an outage or surge, perform only the documented one-time power reset.
As an external check for 9C1, do not perform live mains-voltage measurements unless qualified.
As an external check for 9C1, stop if breakers trip repeatedly, plugs/outlets overheat, or there is arcing.
With 9C1 recorded, record the code and whether the dryer is vented or heat-pump/ventless.
The next non-invasive check is to clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
Important safety warning. When working around a dryer that shows 9C1, keep the checks external and non-invasive. Stop for burning smell, smoke, gas odor, repeated breaker trips, or abnormal overheating. Do not bypass thermal protection.

When to request repair service
Persistent power/voltage codes need the household supply and appliance power/control circuits checked safely before parts are replaced. A repeatable 9C1 event is more useful diagnostically than repeated resets, because it shows when the voltage / power-supply error check is failing.
Book your repair
Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **9C1** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **9C1** before replacing anything.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Dryer 9C1** separate from same-looking codes used by other Samsung appliance families.
