Genuine Daikin 4015250 Outdoor Fan Motor is a compact 70-watt motor that keeps the condenser fan turning so the outdoor unit can shed heat into the air around it. When it begins to fail, the fan might cut in and out, slow noticeably, or refuse to turn while the compressor still loads up. The genuine part delivers the modest output the unit was built around, holding steady airflow where an off-spec motor can run hot or wear out early.
