Genuine Daikin 1879045 Indoor Fan Motor is a 54-watt DC motor running from a 310-volt supply, driving the indoor blower at the variable speeds the unit calls for. Failure often appears as airflow that wavers, a fan that won't settle on a speed, or new running noise. The genuine motor matches the unit's DC control, so the fan holds its set speed instead of drifting the way a substitute can.
