The DF48450CG/S/P is the 48-inch Dual Fuel configuration with four open burners alongside an infrared charbroiler and an infrared griddle. Because the gas manifold and the oven’s high-voltage heating circuit sit in the same chassis, a proper diagnosis checks both systems independently instead of assuming one explains the other.
Because the DF48450CG/S/P carries a gas manifold and a high-voltage oven circuit in one chassis, we shut the gas supply off at the appliance valve before any work near the burners or the manifold, and isolate the range at the breaker before opening the oven’s electrical side. The infrared charbroiler is its own heating assembly with its own burner and igniter, so a charbroiler that will not light says nothing about the open burners beside it. The infrared griddle is a separate heated surface with its own burner and control, and a cold spot on it is a griddle-side diagnosis rather than a cooktop one.
If you are working out exactly which unit you have, the number spells it out: DF for Dual Fuel, 48 for the cabinet width in inches, 4 for the four open burners, C for the infrared charbroiler, G for the infrared griddle and S/P for a stainless front with Professional handles.

Most Common Issues on This Model
Surface burner clicks continuously but will not light
Oven side will not reach temperature while the cooktop works normally
Uneven baking, or a convection fan that is noisy or silent
Display shows one of the Dual Fuel line's numeric fault codes
Charbroiler will not heat, or heats unevenly across its surface
