Possible Causes

Worn blower bearings, Debris in blower wheel, Loose mounting hardware, Imbalanced wheel

How to Fix / Troubleshooting

Safety: Turn off power before touching the blower or mounting hardware.

  • Inspect blower mounting: Check that all blower mounting bolts and brackets are tight. Loose mounts can cause vibration and noise.
  • Check for debris: Remove the blower cover and inspect the wheel for leaves, insects, or buildup. Clean carefully without bending the blades.
  • Spin test: Rotate the blower wheel by hand. If it feels rough, wobbles, or grinds, the bearings are likely worn.
  • Replace blower assembly: Install a new Zodiac-compatible blower assembly if bearings are noisy or the wheel is damaged. Reuse gaskets or replace as needed to maintain proper sealing.
