Excessive vibration or rattling noise from grill body during operation.

Safety first: Unplug the grill and allow moving parts to stop before touching any internal components.

Steps to reduce vibration and noise:

• Identify source: Run the grill briefly with the lid open (at low temp) and listen to locate the noise source (fan area, auger area, or body panels). Then unplug before touching anything.
• Check fan mounting: Access the combustion fan and tighten any loose mounting screws. Ensure the fan housing is not contacting the grill body.
• Inspect auger motor: Tighten auger motor mounting bolts and verify the gearbox is secure. Check that the auger shaft is not rubbing the tube.
• Tighten panels: Check internal heat shields, drip pan supports, and exterior panels for loose screws or bolts. Tighten as needed.
• Balance grill: Ensure the grill is on a level surface and all casters or legs are firmly contacting the ground.

Note: Some fan noise is normal, but loud rattling or grinding should be corrected to prevent premature component wear.
