Possible Causes
Loose blower wheel, failing blower motor bearings, loose panel screws, vibrating flue or ductwork on Ideal furnace installation
How to Fix / Troubleshooting
Safety: Turn off power before tightening or adjusting any components. Keep hands clear of moving parts.
Steps:
- Check panels: Ensure all access panels are properly fitted and screws are tight. Loose panels can rattle loudly.
- Inspect blower wheel: With power off, remove the blower compartment cover and gently move the blower wheel. It should not wobble on the shaft. Tighten the set screw if loose.
- Listen to bearings: A high-pitched squeal often indicates worn motor bearings. This requires blower motor replacement by a technician.
- Secure ductwork: Check nearby ducts and flue pipes for contact with framing; add supports or padding where necessary.
