Smoker makes loud rattling or grinding noises during operation.

Safety first: Unplug the smoker before investigating noises.

• Identify source: Run the smoker briefly with supervision to locate the noise area, then unplug before touching anything.
• Check fan assembly: Access the fan and ensure the blade is tight on the motor shaft and free of debris.
• Tighten hardware: Tighten any loose screws on internal panels, racks supports, and the cabinet.
• Replace noisy fan: If the fan motor makes grinding sounds even when clean and tight, replace the convection fan motor assembly.
