OEM Lennox ECM 5.0 Eon Blower Motor (No Module) — 10B67

The genuine OEM Lennox 10B67 is an ECM 5.0 Eon variable-speed blower motor, supplied as the motor only (control module not included). This electronically commutated motor drives the indoor blower in compatible Lennox furnaces and air handlers, continuously adjusting speed to deliver precise, energy-efficient airflow for both heating and cooling while running quieter than a standard PSC motor.

Common failure symptoms: A failing ECM motor may hesitate or rock back and forth on start-up, run intermittently, cycle on and off, produce grinding or humming noises, or stop entirely — leaving you with no airflow, weak airflow, or inconsistent comfort between rooms. Because the module and motor are separate on this platform, confirm the motor is the failed component before ordering; the existing module transfers to this replacement.

Why OEM matters: Lennox pairs the ECM 5.0 Eon motor to its specific control module, blower housing, and system programming. A non-OEM or mismatched motor can fault the module, disrupt airflow staging, and undermine the efficiency ratings your equipment was certified to. The factory 10B67 guarantees correct electrical fit and communication so your Lennox system runs at rated performance.
