Smoker makes loud rattling or grinding noises during operation.

Safety first: Unplug and cool the smoker before inspection.

Steps:

• Check racks and pans: Ensure all racks and trays are properly seated and not vibrating against the walls.
• Inspect fan assembly: Access the fan and check that the blade is tight on the motor shaft and not contacting the shroud. Tighten or adjust as needed.
• Secure panels: Tighten any loose screws on interior and exterior panels.
• Replace fan motor: If noise persists and seems to come from the motor itself, replace the fan motor.
