Consistent, rated airflow is what allows the refrigerant to condense properly, so this motor is essential to your Lennox system's cooling capacity and efficiency. It is built for continuous outdoor duty against heat, weather, and vibration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e the outdoor fan runs slowly or not at all, the unit overheats and trips on high-pressure lockout, warm air from the vents, loud humming or bearing noise, or a motor that's hot to the touch and shuts down after a few minutes. A failing fan motor frequently causes the compressor to overheat, so prompt replacement protects the rest of the system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the \u003cstrong\u003e78F90\u003c\/strong\u003e matches your Lennox unit's exact horsepower, RPM, rotation direction, and shaft dimensions.
