2. Setup and Initial Use
2.1 Assembly
Assembly of the Masterbuilt smoker typically requires more time than initially estimated. Take your time and follow the instructions carefully. Ensure all components, especially the leg kit, are securely fastened for stability. The unit is designed for outdoor use only.
2.2 Initial Curing Process
Before first use, it is crucial to perform an initial curing process to burn off any manufacturing oils and residues. Follow the detailed instructions in the official user manual for this process. This step helps to properly season the smoker and prepare it for cooking.
For detailed assembly and curing instructions, please refer to the Official User Manual (PDF).
3. Operating Instructions
3.1 Digital Control Panel
The digital control panel, located on top of the smoker, allows for precise temperature and time management. Use the arrow buttons to adjust the desired temperature up to 275°F and set the cooking timer. Indicator lights provide status updates.

3.2 Wood Chip Loader
The patented side wood chip loader allows you to add wood chips without opening the main smoker door, ensuring consistent smoke and heat retention. Simply pull out the loader, add your preferred wood chips, and push it back in to drop them onto the heating element.

3.3 Adjustable Air Damper
Control the amount of smoke and airflow using the adjustable air damper located on the top of the smoker. Adjusting this damper allows you to fine-tune the smoke intensity for different types of food.

3.4 Internal Racks and Capacity
The smoker features four chrome-coated smoking racks, providing 970 square inches of cooking space. These racks are removable, allowing you to customize the interior for larger items like turkeys or roasts. The spacious vertical design can accommodate up to 16 chickens, 4 turkeys, 8 pork butts, or 8 racks of ribs.


3.5 Monitoring Food
A convenient window in the smoker door allows you to monitor your food's progress without opening the door, thus preventing heat and smoke loss. The lockable door latch ensures a tight seal to retain heat and smoke inside the fully insulated smoker body.
4. Maintenance and Cleaning
Regular cleaning is essential for maintaining your Masterbuilt smoker's performance and longevity. The smoker is designed with features to simplify this process.
4.1 Water Bowl and Grease Tray
The removable water bowl serves a dual purpose: it adds moisture to your smoked foods and catches drippings. The removable rear grease tray makes it easy to clear excess grease, ensuring a cleaner cooking environment and simpler cleanup.

4.2 General Cleaning
After each use, allow the smoker to cool completely. Remove racks, water bowl, and grease tray for cleaning. Wipe down the interior and exterior surfaces as needed. While some seasoning is normal and desirable for a smoker, excessive buildup should be cleaned to ensure optimal performance.
5. Troubleshooting
If you encounter issues with your Masterbuilt smoker, consider the following common troubleshooting tips:
- Temperature Control: If the smoker struggles to reach or maintain the set temperature, ensure the door is properly latched and the air damper is adjusted correctly. External factors like extreme cold or wind can also affect performance.
- Error Messages: If the digital display shows an error message, consult the official user manual for specific error codes and their corresponding solutions.
- Smoke Production: Ensure wood chips are properly loaded and the heating element is functioning. Adjust the air damper to control smoke levels.
