Lennox 10B68 Control Module Kit

The Lennox 10B68 Control Module Kit is a direct OEM replacement designed for high-efficiency ECM blower motors found in a wide range of Lennox, Armstrong, and Ducane residential gas furnaces and air handlers. As a veteran-grade motor control module kit, it serves as the "brain" for variable-speed blower assemblies, managing airflow ramps, static pressure adjustments, and signal processing from the main furnace control board. When the indoor blower fails to start or exhibits erratic RPM fluctuations, a breakdown in the ECM motor end cap electronics is often the culprit. This kit allows technicians to replace the integrated control module separately from the motor windings, provided the 3-pin internal connector and phase-to-phase resistance tests are within spec.

Engineering-wise, the 10B68 (also identified under part number 10B6801) ensures precise torque and speed control for Genteq 3.0 and similar constant torque motors. Compatibility includes popular high-efficiency series like the Lennox EL297UHE and EL196UHE units. Swapping the module requires disconnecting the 4-pin signal and 5-pin power harnesses, removing the two hex-head mounting bolts, and ensuring a proper drip loop is maintained during re-installation. Using a genuine Lennox replacement part ensures that the factory-programmed airflow profiles and communicating logic remain consistent with the unit's original design parameters.

• Compatible with Lennox, Armstrong, and Ducane high-efficiency HVAC equipment.
• Restores variable speed blower functionality without the cost of a full motor assembly replacement.
• Factory-programmed ECM motor module ensures accurate airflow and static pressure response.
• Durable OEM construction facilitates a seamless bolt-on installation using existing hardware.
• Critical for maintaining system AFUE ratings and consistent indoor air distribution.

• How do I verify if the module is bad versus the motor? Check phase-to-phase resistance on the 3-pin motor connector; if the motor windings show equal resistance and no short to ground, the 10B68 module is the likely failure point.
• Does this require special programming in the field? No, this motor control module kit comes pre-configured with the necessary protocols for compatible Lennox systems.
• What are the signs of a failing 10B68? Common indicators include a "clunking" start-up, the blower motor "hunting" for speed, or a complete lack of airflow despite receiving a 24V signal.
