Grill makes rattling or vibrating noise from under the cook chamber during operation.

Safety first: Turn off and unplug the grill before tightening any hardware.

Steps to eliminate rattle:

• Access fan area: Remove lower or rear panels to reach the combustion fan.
• Tighten screws: Check and tighten all fan mounting screws and nearby sheet metal fasteners.
• Inspect fan blades: Ensure blades are not bent and do not contact the housing. Replace the fan if damaged.
• Secure panels: Tighten any loose internal heat shields or baffles.
