If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
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.
