Smoker produces a loud buzzing, humming, or rattling noise during operation.

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

• Identify source: Run the smoker briefly and listen carefully to locate the noise source, then turn it off and unplug.
• Tighten screws: Check and tighten screws on the door, hinges, internal panels, and element brackets.
• Secure trays: Ensure the wood chip tray and drip pan are fully seated and not loose. Bend tabs slightly if needed to reduce play.
• Check leveling: Make sure the smoker is on a level surface and all legs or casters are stable.
