What causes the infrared burner on my Napoleon Grill to flash back?
- DDenise FloresAug 31, 2025
If the infrared burner on your Napoleon Grill flashes back (makes a loud “whoosh” sound, followed by a continuous blow-torch type sound and grows dim), it could be due to ceramic tiles overloaded with grease, clogged ports, overheating due to inadequate ventilation, a cracked ceramic tile, or a leaking gasket. Turn the burner off and allow it to cool for at least two minutes. Relight the burner and burn on high for at least five minutes or until the ceramic tiles are evenly glowing red. Ensure that no more than 75% of the grill surface is covered. Allow burner to cool and inspect very closely for cracks.
