What to do if the infrared burner flashes back on my Napoleon ROGUE SE 425 RSIB Grill?

If the Napoleon Grill's infrared burner flashes back, characterized by a loud 'whoosh' sound and a dimming flame, turn off the burner and let it cool for at least two minutes. Relight it and burn on high for at least five minutes, ensuring the ceramic tiles glow evenly red. Make sure no more than 75% of the grill surface is covered. If the issue continues, allow the burner to cool, inspect for cracks, and contact your Napoleon dealer for a replacement if needed. This issue can be caused by ceramic tiles overloaded with grease, clogged ports, overheating due to inadequate ventilation, cracked ceramic tiles, or a leaking gasket.
