The DF48450DG/S/P is the 48-inch Dual Fuel configuration with four open burners alongside an infrared dual 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 DF48450DG/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 dual griddle doubles the heated plate area and runs on two independently controlled infrared burners, so one half going cold while the other stays hot is a normal symptom pattern and a useful one to report.
For anyone matching parts or a replacement, the number reads as DF for Dual Fuel, 48 for the cabinet width in inches, 4 for the four open burners, DG for the infrared dual 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
Dual griddle will not heat, or heats unevenly across its surface
