Maintenance
Cleaning the Ash System
Regular cleaning of the ash system is crucial for optimal performance. After each use, allow the grill to cool completely. Open the ash door and use the provided ash tool to scrape any remaining ash and debris into the ash pan. Dispose of ash safely.
Ensure the ash pan is clean before starting a new cook to prevent airflow restrictions and maintain consistent temperatures.
General Care
- Clean cooking grates after each use with a grill brush.
- Wipe down exterior surfaces with a damp cloth. Avoid abrasive cleaners.
- Periodically check and tighten all hardware, especially U-bolts on clasps, to ensure proper sealing and sensor activation.
- Store the grill in a dry, covered area when not in use to protect it from the elements.
Troubleshooting
This section addresses common issues you might encounter with your Masterbuilt Gravity Series 1050 grill.
| Problem | Possible Cause | Solution |
|---|---|---|
| Grill not reaching desired temperature or fan not running. | Lid, hopper, or ash door not fully closed, preventing safety switches from engaging.
