In brief
Fault code E154 on Samsung Mural / Cassette means: Fault code E154 indicates that the indoor fan speed is not detected (no tachometer feedback). Most common cause: Mechanically blocked fan wheel (object, excessive dust), faulty fan motor, start capacitor (on older AC models) or electronic board (motor control circuit). First action: Push the fan wheel with a pen (power off): it should rotate freely without resistance.. Call a registered engineer if the fault returns after basic checks or involves refrigerant work (F-Gas registered engineer required).
According to the Samsung Service Manual, the most common cause of E154 is a mechanically blocked fan wheel or a faulty fan motor.
