How to Fix / Troubleshooting

Safety: Turn off power before removing inducer assembly or covers.

Steps:

  • Inspect inducer wheel: Remove inducer cover if accessible and check for debris (insulation, leaves) in the wheel. Clean carefully.
  • Check for water: On high-efficiency models, ensure condensate is draining and not pooling in the inducer housing.
  • Spin by hand: With power off, spin the inducer wheel. Roughness, grinding, or excessive play indicates bearing failure.

If the inducer is noisy or seized, replace the inducer assembly with the correct Goodman OEM part. This is typically a professional-level repair.
