For the Samsung Oven & Range families covered by the source set, **E-0b** means **cooling motor blocked**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **E-0b**. Search normalization stores it as **E0B** while preserving the characters a homeowner actually sees.

Cooling motor blocked.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E0B 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 can refuse to start or continue a cycle.
E-0b can be accompanied by this pattern: a door, lid, divider, or latch may not be recognized as closed or locked.
The E-0b display becomes more meaningful if the code can return immediately when the appliance reaches a door-safety verify.
On affected Samsung oven or range models, e-0b appears on the range/oven and the related cooking, sensing, door, or control function can be limited.
Why it happens
Possible causes
varies by model/region — cross-region baseline — Cooling motor blocked
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.
For E-0b, start by doing this: remove clothing, racks, cookware, packaging, or debris that can interfere with closure.
The next non-invasive check is to inspect the visible latch/strike area for obstruction or damage without bypassing the safety interlock.
With E-0b recorded, if water is trapped in a washer or dishwasher, resolve the drain condition before trying to force the door open.
Before opening any service area, record the exact code and model number.
The next non-invasive check is to check door/divider/pan placement, vent obstruction, settings, and household power only when relevant.
Important safety warning. 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. For E-0b, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

When to request repair service
If the owner-accessible checks do not clear E-0b, 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. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Resetting can clear a temporary state, not a persistent issue. If **E-0b** 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 **E-0b** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
The code alone is not enough to justify a part. **E-0b** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
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 **Oven & Range E-0b** separate from same-looking codes used by other Samsung appliance families.
