Possible Causes

Aging Daikin inducer motor bearings, Debris in inducer wheel, Misaligned inducer housing, Excessive condensate in inducer assembly

How to Fix / Troubleshooting

Safety: Turn off power and gas before inspecting the inducer. Do not operate the furnace with a failing inducer motor.

Steps to check:

  • Listen closely: Confirm the noise originates from the inducer housing (top/front of furnace) and not from the blower or ductwork.
  • Inspect for debris: Remove the inducer cover if accessible and check for foreign objects in the wheel.
  • Check for water: Look for signs of water accumulation in the inducer housing, which may indicate a condensate drainage issue.

Inducer motors are sealed units; bearing noise usually means the Daikin inducer assembly must be replaced by a technician.
