Lennox 16A66, also listed as Lennox LB-94724AL, is an OEM induced draft blower motor designed to ensure proper combustion airflow and safe venting in compatible Lennox gas furnaces. This induced draft blower plays a critical role in pulling flue gases through the heat exchanger and vent system, helping the furnace ignite reliably and operate within manufacturer specifications.

This OEM Lennox induced draft blower features a 9 inch housing and a 1/20 HP motor engineered for variable-speed operation. With a wide operating range of 33–110 VAC and 60–180 Hz, the motor delivers flexible performance across multiple furnace platforms. The variable RPM range of 1500 to 4700 allows the control board to precisely regulate airflow based on system demand, improving combustion efficiency and overall furnace reliability.

Built to Lennox factory standards, the 16A66 induced draft blower is designed for long service life in high-temperature furnace environments. OEM construction ensures proper fit, correct electrical characteristics, and quiet, balanced operation when installed as a direct replacement. Using a genuine Lennox draft inducer helps prevent ignition faults, pressure switch errors, and incomplete venting issues commonly associated with worn or non-OEM replacement motors.

This part is commonly used in high-efficiency Lennox gas furnaces that require a variable-speed induced draft motor. Always confirm compatibility using the furnace model and serial number before ordering to ensure proper fit and operation.
