Built to Lennox factory specifications, it is matched to the airflow programming and control interface of the platforms it was designed for, delivering precise comfort staging and lower energy consumption.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e the blower not starting or shutting down mid-cycle, surging or fluctuating fan speeds, furnace control error codes, intermittent operation, clicking from the control module with no rotation, and bearing noise. As with most ECM motors, the electronic module often fails before the motor itself.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the \u003cstrong\u003e81W63\u003c\/strong\u003e arrives with the correct factory airflow profiles for its Lennox system.
