Product Identity

This Nexgrill heat diffuser carries part number 04004549A0 and measures 17 1/4" X 5". It is a genuine appliance part designed to sit above the burner and spread heat evenly across the cooking surface. The component is sold new as a single unit.

Compatibility Guidance

The diffuser fits three specific grill models: Kenmore 122.16654900 and Nexgrill 810-0010 plus 860-0003. Owners of any other grill make or model should verify their part number before ordering because this item will not align with different burner configurations.

Critical Dimension

The 17 1/4" X 5" footprint is the single specification that determines fit; if the original diffuser on your grill does not match these exact measurements the part will not seat correctly and heat distribution will be compromised.

Questions about this item

When should the 17 1/4" X 5" heat diffuser be replaced on my 860-0003 grill?

Replace the diffuser when the metal shows warping, deep pitting or holes that let flames contact food directly.

What part fails first on the NEX04004549A0 diffuser during long grilling sessions?

The thin steel edges warp first under sustained high heat, creating uneven protection for the burners below.

How much hotter does the grill run once this diffuser is installed and used all day?

The diffuser spreads heat evenly across the 17 1/4" surface, reducing flare-ups without raising overall grill temperature.
