Behonor F0510B2944 Attic Ventilation Motor – Lomanco 2000/1800 Series Replacement Kit

The Behonor F0510B2944 is a replacement motor kit for Lomanco 2000 and 1800 series powered attic ventilators. When an attic fan starts humming without spinning, runs noisily or stops altogether, swapping the motor is usually far less work than replacing the whole roof-mounted unit.

Motor specifications

• Voltage: 120 V, 60 Hz
• Current: 3.4 A
• Speed: 1100 rpm
• Power: 1/10 HP

Those numbers are what to compare against the label on your old motor. Matching voltage, speed and horsepower keeps the fan blade turning at the rate the ventilator was designed for, so airflow stays where it should be.

What comes in the kit

Along with the F0510B2944 motor, the box contains three bridge pieces, three locking nylon nuts and an instruction manual. The bridge pieces are the mounting brackets that hold the motor in the ventilator frame, and the nylon-insert nuts resist loosening from vibration, which matters on a fan that runs for hours through hot weather.

A working attic fan pulls hot, humid air out of the attic space, helping keep heat from building up under the roof deck in summer. How much difference you notice depends on your attic's size, intake vents and layout, but a seized motor provides no ventilation at all.

Before you start: shut off power to the fan at the breaker, note how the old motor is wired before disconnecting it, and work from a stable position in the attic. Motor manufacturer Behonor designed this kit specifically around the Lomanco 2000 and 1800 series, so confirm your model before ordering.
