On the DF48450F/S/P, the 48-inch top carries four open burners alongside a French top and runs on gas, while the oven underneath is electric and convection-assisted. That split means a no-heat complaint has two completely separate diagnostic paths depending on which half of the range it came from.
The DF48450F/S/P’s oven uses convection, so uneven baking is worth separating from no-heat. A cavity that heats but browns unevenly often traces to a convection fan motor or a sensor reading slightly off, while a cavity that never warms is an element or relay question. The French top is a solid heated plate with a hot centre and a cooler perimeter by design — a gradient that is intentional, not a fault, though a top that never gets hot in the middle is.
Read the number back and it describes the appliance: DF for Dual Fuel, 48 for the cabinet width in inches, 4 for the four open burners, F for the French top and S/P for a stainless front with Professional handles.
