Deciding whether to fix an attic fan often comes down to one part: the motor. When the fan stops spinning, the rest of the assembly is usually fine, so a targeted replacement can save the unit. Without a matching motor, the attic loses its ventilation and the house feels the heat. This replacement motor is aimed at exactly that scenario.
Quick verdict: For a homeowner who has already confirmed the old motor's shaft and mounting setup, this is a focused fix at USD 45.95. Rather than replacing the entire fan assembly, you address the failed component directly.
Who it suits: This motor is for the person repairing a Lomancool 2000 or 1800 attic fan, and it also lists some Broan models in its compatibility. It runs on a 115-volt, 60Hz supply and draws 3.4 amps. The motor body is 5 inches in diameter, with a 1/2-inch shaft that measures 1.75 inches and has a flat along it. If those dimensions match the motor you're removing, this is the part. It's a straightforward replacement for someone comfortable with basic attic fan repairs.
What stands out from the listed details: The package includes three mounting brackets and nylon locking nuts, so you avoid a separate hardware run. There are three studs on the back of the motor, which points to a standard three-point mounting pattern. A one-year manufacturer warranty also gives a defined coverage window. The model cross-reference helps too because it replaces older motors carrying numbers like A0416B2059 and A0510B2389.
Meaningful trade-offs: This is not a universal fit. You need to verify your fan's mounting pattern and rotation direction; the motor spins clockwise when you face the shaft. The speed rating is modest, which suits attic venting duties but not high-speed work. And because this is a bare motor, you'll be reusing the existing fan blade, housing, and wiring from your current setup. Be sure the shaft length and flat orientation work with the fan blade assembly you have.
Bottom line: If the geometry and rotation match your existing fan, USD 45.95 is a sensible repair investment. Those measurements are the gate before ordering.
