Grill struggles to reach or maintain high temperatures (e.g., cannot exceed 350°F) even with lid closed.

Safety first: Allow the grill to cool before disassembling internal parts.

Step-by-step checks:

• 1. Confirm pellet quality: Use fresh, dry hardwood pellets. Discard any that are swollen or crumbly.
• 2. Clean firepot and burn area: Remove ash and debris that can restrict airflow and reduce combustion efficiency.
• 3. Inspect fan and intake: Ensure the combustion fan spins freely and the air intake is not blocked by grease, foil, or debris.
• 4. Check exhaust path: Clean the chimney and interior surfaces to remove heavy soot that can restrict exhaust flow.
• 5. Inspect lid seal: Check the door/lid gasket for gaps or damage. Replace with a Grilla Grills-compatible gasket if heat is visibly escaping.

When to call a technician: If the grill still cannot reach high temperatures after cleaning and gasket replacement, the fan or control board may need professional diagnosis.
