Rattling or vibrating noise from fan area during operation.

Safety first: Unplug the grill and allow moving parts to stop before accessing the fan.

Steps to fix noise:

• Access fan: Remove the lower or rear access panel to reach the combustion fan.
• Inspect blades: Check for bent blades or debris stuck in the fan. Carefully straighten minor bends or remove debris.
• Tighten mounting: Ensure all fan mounting screws are tight and the fan housing is secure.
• Replace if damaged: If the fan blade is cracked or severely bent, replace the entire combustion fan motor assembly.
