Grill cannot reach high temperatures (e.g., stuck below 350°F) even with lid closed.

Safety first: Allow the grill to cool before deep cleaning. Wear gloves and a dust mask when handling ash.

Steps to improve heat:

• Deep clean firepot: Remove internal components and vacuum all ash from the firepot and air holes.
• Check fan strength: Start the grill and feel for strong airflow from the combustion fan into the firepot area. Replace the fan if airflow is weak or intermittent.
• Use fresh pellets: Empty the hopper and refill with dry, high-quality hardwood pellets recommended by Z Grills.
• Inspect door and seals: Ensure the lid closes fully and that there are no large gaps allowing excessive heat loss.
