For the Samsung Oven & Range families covered by the source set, **door** means **oven door not detected as closed**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. 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 **door**. Search normalization stores it as **DOOR** while preserving the characters a homeowner actually sees.

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, open and close the door or lid firmly without forcing it.
To rule out an accessible cause, remove clothing, racks, cookware, packaging, or debris that can interfere with closure.
For door, start by doing this: inspect the visible latch/strike area for obstruction or damage without bypassing the safety interlock.
For door, start by doing this: if water is trapped in a washer or dishwasher, resolve the drain condition before trying to force the door open.
As an external check for door, record the exact code and model number.
To rule out an accessible cause, verify door/divider/pan placement, vent obstruction, settings, and household power only when relevant.
Important safety warning. When working around an oven or range that shows door, keep the checks external and non-invasive. Stop for arcing, repeated breaker trips, uncontrolled heating, damaged wiring, or gas odor. Internal live-voltage and gas-system diagnosis is not a homeowner check.

When to request repair service
Once door has returned after the safe checks, Request service if the door closes normally but the code returns, the latch will not release safely, or diagnosis requires testing the interlock, wiring, or control circuit. Preserve any accompanying noise, water level, temperature, or operating-stage details for the technician.

Resetting can clear a temporary state, not a persistent issue. If **door** comes back, preserve the code and move to the safe checks or model-specific service path.
Do not keep operating the appliance through a hazardous symptom just to see whether **door** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
No. **door** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
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.
