Broil King Combustion Fan Imbalance or Bearing Wear

Grill makes loud rattling or humming noise from fan area

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

Debris caught in fan blades, Loose fan mounting screws, Bent fan wheel, Worn fan motor bearings

Safety first: Unplug the grill before accessing the fan.

Access fan: Remove the side or rear panel to reach the combustion fan.
Inspect blades: Remove any debris or grease buildup from the fan wheel. Ensure no wires are contacting the blades.
Tighten mounts: Check and tighten the fan mounting screws.
Spin test: Rotate the fan by hand. If it feels rough or wobbles, the motor bearings or wheel may be damaged.
Replace fan assembly: Install a new Broil King-compatible combustion fan assembly if noise persists.
