Smoker makes popping or clicking noises during heating and cooling.

Safety first: Normal expansion noises are generally harmless, but investigate any sudden loud bangs.

• Secure racks: Ensure racks are fully seated in their rails and not loose.
• Check element mounts: With the smoker cool and unplugged, verify the heating element brackets are tight.
• Inspect cabinet seams: Tighten any loose screws on the outer cabinet that may allow panels to flex excessively.
• Monitor changes: If noises become louder or are accompanied by performance issues, inspect for structural damage.
