Possible Causes
How to Fix / Troubleshooting
Safety: Turn off power before touching the inducer assembly. Do not attempt to force the inducer to spin while powered.
Steps to check:
- Spin test: With power off, try to spin the inducer wheel gently by hand. It should rotate freely without grinding.
- Inspect for debris: Look for foreign objects in the inducer housing or vent connection.
- Listen on startup: Restore power and call for heat. If the motor only hums and does not start, it is likely failing.
When to call a technician: Inducer motor replacement and sealing to the heat exchanger should be done by a professional.
