If a Samsung oven or range shows **C-24**, the verified Samsung meaning in this research set is **oven temperature rising faster than normal, commonly associated with a blocked vent**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **C-24**. Search normalization stores it as **C24** while preserving the characters a homeowner actually sees.

Quick answer
Oven temperature rising faster than normal, commonly associated with a blocked vent.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so C24 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
One clue that supports the C-24 diagnosis is that the appliance can refuse to start or continue a cycle.
C-24 can be accompanied by this pattern: a door, lid, divider, or latch can not be recognized as closed or locked.
C-24 can be accompanied by this pattern: the code can return immediately when the appliance reaches a door-safety check.
When the C-24 condition is present, c-24 appears on the range/oven and the related cooking, sensing, door, or control function can be limited.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
To rule out an accessible cause, open and close the door or lid firmly without forcing it.
For C-24, start by doing this: remove clothing, racks, cookware, packaging, or debris that can interfere with closure.
For C-24, start by doing this: inspect the visible latch/strike area for obstruction or damage without bypassing the safety interlock.
A safe owner-level check is to if water is trapped in a washer or dishwasher, resolve the drain condition before trying to force the door open.
With C-24 recorded, record the exact code and model number.
Before opening any service area, 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. If resolving C-24 would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
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. In a service visit for C-24, model-specific testing should follow the oven temperature rising faster than normal, commonly associated with a blocked vent circuit rather than treating the code as proof of one failed part.

Resetting can clear a temporary state, not a persistent issue. If **C-24** comes back, preserve the code and move to the safe checks or model-specific service path.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **C-24**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
No. **C-24** 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. This page therefore keeps **Oven & Range C-24** separate from same-looking codes used by other Samsung appliance families.
