Possible Causes
Imbalanced blower wheel, debris caught in the blower, loose mounting of the Ideal furnace to its base, or flue or duct resonance.
How to Fix / Troubleshooting
Safety: Turn off power before inspecting the blower or ductwork.
Steps:
- Inspect blower wheel: Remove the blower access panel and check for debris (insulation, screws, etc.) inside the blower wheel. Remove any foreign objects.
- Check mounting: Ensure the furnace cabinet is firmly secured to its base or platform and that any anti-vibration pads are intact.
- Observe operation: After reassembly, run the furnace and note if vibration is reduced. Persistent heavy vibration suggests a bent or imbalanced blower wheel that should be replaced.
