If a Samsung dryer shows **Cg**, the verified Samsung meaning in this research set is **vent blockage detected**. 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 **Cg**. Search normalization stores it as **CG** while preserving the characters a homeowner actually sees.
Content status: Verified
Vent blockage detected.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so CG may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Important safety warning. Stop for burning smell, smoke, gas odor, repeated breaker trips, or abnormal overheating. Do not bypass thermal protection. Do not bypass a safety device merely to see whether Cg disappears.
Service is not automatically required. Request diagnosis only if the status cannot be cleared as designed or normal operation does not resume. In a service visit for Cg, model-specific testing should follow the vent blockage detected circuit rather than treating the code as proof of one failed part.

Vent blockage detected.
You can try the one reset Samsung documents for the model, but **Cg** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
The display can be normal in the documented context. If **Cg** appears unexpectedly, cannot be cleared, or prevents normal operation, then the issue deserves diagnosis.
Treat **Cg** as a starting point, not a replacement instruction. Wiring, feedback signals, operating conditions, and electronic controls can mimic a failed component.
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 Cg** separate from same-looking codes used by other Samsung appliance families.
