Photograph the model/serial label, cycle selection, error display and accessible vent layout. Note fuel type, recent installation or move, whether a breaker tripped, whether other gas appliances work normally, and when the symptom began. Also record load size and whether the symptom occurs on every heat-enabled cycle, because that distinction helps support teams avoid a misleading single-cycle diagnosis. Use Samsung’s reset guidance only when its stated conditions fit; a reset can clear a transient state but does not repair a recurring airflow, supply or component fault.
Stop immediately for smoke, burning odour, scorching, sparking, abnormal gas smell or repeated power trips. Keep the door switch and thermal devices intact; never test live terminals, light a burner manually or assume a generic button combination applies to every model. If safe external checks do not restore heat, Samsung’s official no-heat flow directs the unresolved case to service.
