Possible Causes

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

How to Fix / Troubleshooting

Safety first: Unplug the grill and allow it to cool before accessing the fan.

  • Access fan: Remove the side or rear panel to expose the combustion fan assembly.
  • Inspect blades: Remove any debris, grease, or ash from the fan blades. Straighten slightly bent blades carefully.
  • Check mounting: Tighten any loose screws or brackets securing the fan to the housing.
  • Spin test: Rotate the fan by hand. If it feels rough, wobbles, or grinds, the motor bearings are likely worn and the fan motor should be replaced.
  • Reassemble and test: Reinstall panels, plug in the grill, and run a startup to confirm noise is resolved.
