Excessive smoke leaks from around the door and seams, making it hard to maintain temperature.

Safety first: Work on the smoker only when it is cool and unplugged.

Steps to reduce smoke leakage:

• Replace door gasket: If the gasket is brittle or torn, remove it and clean the mounting surface. Install a new Landmann-compatible high-temperature gasket, pressing firmly along the entire length.
• Inspect cabinet seams: Look for gaps where panels join. Tighten any loose screws or rivets. Small gaps can be sealed with high-temperature silicone sealant on the exterior.
• Check exhaust vent: Ensure the vent damper is present, moves freely, and can be adjusted to control smoke flow. Replace if missing or damaged.
• Test with a smoke run: Run the smoker with a small wood load and observe where smoke escapes. Address remaining leaks as needed.
