On the DF48850/S/P, the 48-inch top carries eight open burners 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.
On the DF48850/S/P, a cooktop that ignites fine while the oven refuses to reach temperature is the classic split-diagnosis case: the gas side is healthy and the fault sits in the electric bake or broil circuit, the temperature sensor, or the relay board driving them.
Read the number back and it describes the appliance: DF for Dual Fuel, 48 for the cabinet width in inches, 8 for the eight open burners, the 50 or 51 before the option letters for the control generation and S/P for a stainless front with Professional handles.
