Uneven cooking; one side of the grill is much hotter than the other.

Safety first: Allow the grill to cool before adjusting internal components.

• Inspect the heat diffuser: Remove and check the Nexgrill heat diffuser/heat baffle for warping or misplacement. Reinstall it correctly centered over the fire pot.
• Clean air holes: Ensure all air holes around the fire pot are clear of ash.
• Rotate food and use zones: Until perfect balance is restored, place sensitive foods away from the hotter side and rotate them during cooking.
• Shield from wind: Position the grill so wind does not blow directly into the side vents or under the lid.
