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

Worn blower motor bearings, Loose blower wheel, Debris in blower housing, Resonance in vent piping

Safety: Turn off power and gas before removing blower covers.

Inspect blower wheel: Remove the blower access cover and check for debris or foreign objects contacting the wheel. Clean carefully.
Tighten mounting hardware: Ensure blower mounting bolts and vent connections are tight to reduce vibration.
Check motor bearings: Spin the blower wheel by hand. If it feels rough or wobbly, replace the blower assembly.
Support vent piping: Add hangers or supports to long vent runs to reduce resonance and rattling.
