Condenser Fan Motor
Internal bearing wear or failure of the thrust washers allows the motor shaft to shift along its axis or tilt under the aerodynamic load of the blades. This deviation from the center axis causes the blade tips to exceed their clearance tolerances and strike the surrounding shroud.

Fan Motor Mounting Grommet Set
These rubber isolators decouple the motor vibration from the chassis; when they degrade or 'dry rot' from outdoor exposure, the motor loses level support. The resulting tilt causes the fan blade to rotate on an elliptical path relative to the shroud, leading to mechanical interference.

Condenser Fan Blade
Centrifugal forces acting on a weakened or previously impacted aluminum blade can cause 'blade creep' or warping. If the blade pitch is altered or the hub is no longer perpendicular to the shaft, the blade tip will strike the shroud at specific points in its rotation.
