OEM Lennox Motor Mount Band — 50W89

The genuine OEM Lennox 50W89 motor mount band is the steel support strap that cradles and secures a blower or condenser fan motor inside your Lennox unit. It holds the motor in precise alignment with the fan wheel or blade while its integral isolation points absorb vibration, keeping the motor quiet, balanced, and running true. Because Lennox motor housings are dimensioned to specific band diameters and bolt spacing, using the correct 50W89 band is essential for a secure, rattle-free fit.

Common failure symptoms: a worn, cracked, or corroded mount band lets the motor sag or shift, producing loud vibration, a metallic buzzing or rattling noise, wobble in the fan wheel, and accelerated bearing wear. In severe cases the motor can drop out of alignment and contact the blower housing or blades.

Why OEM matters: aftermarket bands often use lighter-gauge steel or slightly different geometry that won't clamp a Lennox motor securely, leading to renewed vibration and premature failure. The factory 50W89 band is built to Lennox's exact specifications for gauge, diameter, and mounting-point placement, ensuring a proper fit, correct motor position, and long service life.
