Furnace cabinet vibrates excessively or rattles loudly during operation.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

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

Possible Causes

Loose blower housing or motor mounts, Unbalanced blower wheel, Loose panel screws, Ductwork not properly supported

Safety: Turn off power before tightening or adjusting mechanical components.

Steps to check:

Tighten panels: Ensure blower and burner doors are properly seated and all screws are tight.
Inspect blower mounts: Check that the blower housing is firmly secured to the furnace and that motor mounting bolts are tight.
Check blower wheel: Look for bent fins or debris stuck in the wheel. An unbalanced wheel may need replacement.
Support ducts: Add or adjust hangers on nearby ductwork to reduce vibration transfer.
