Grill struggles to reach high temperatures (e.g., cannot exceed 350–400°F) even on maximum setting.

Safety first: Turn off and unplug the grill; allow it to cool fully.

• Deep clean fire pot and burn chamber: Remove all internal components and thoroughly clean ash from the fire pot, burn chamber, and under the drip tray.
• Clean combustion fan and air inlets: Access the fan and remove dust, ash, and grease. Ensure intake holes and exhaust paths are clear.
• Use high-quality pellets: Replace pellets with a premium, dry hardwood pellet. Avoid pellets stored in humid environments.
• Check lid seal: Inspect the lid and any gasket material for gaps or warping. Replace the lid gasket if present and damaged.
• Test again: After cleaning and pellet replacement, run the grill on its highest setting and monitor temperature. If it still cannot reach target, the combustion fan or control board may be under-driving the fire and may need service.
