Possible Causes

Worn inducer bearings, Debris in inducer wheel, Loose inducer mounting, Water intrusion into inducer housing

How to Fix / Troubleshooting

Safety: Turn off power and gas before servicing the inducer. Components may be hot.

Steps:

  • Inspect inducer: Remove the burner access panel and locate the inducer assembly. Check for loose mounting screws and tighten.
  • Listen closely: Briefly run the furnace and confirm the noise originates from the inducer, not the blower.
  • Check for water: On condensing models, ensure condensate is not backing up into the inducer due to a clogged drain.

Note: Inducer motors are sealed units; if bearings are noisy, the entire inducer assembly should be replaced with a Concord-approved part.
