What is the correct rotation for the Lennox 32624?
The 32624 is a clockwise (CW) rotation wheel, determined by looking at the hub end. Installing the incorrect rotation will significantly reduce airflow and can overheat your blower motor.

Does this wheel fit other brands besides Lennox?
Yes, as an OEM-spec part, it is commonly cross-referenced for use in Allied, Armstrong, Concord, and Ducane equipment. Always verify the individual furnace blower wheel dimensions before installation.

What causes a blower wheel to fail?
Typically, failure is caused by excessive dust accumulation leading to imbalance, or a loose set screw on the 1/2-inch bore. Professionals should check the motor shaft for scoring whenever replacing a centrifugal wheel.
