On the DF604CF, the 60-inch top carries four open burners alongside an infrared charbroiler and 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.
On the DF604CF, 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. 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 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.
The suffix carries more information than people expect: DF for Dual Fuel, 60 for the cabinet width in inches, 4 for the four open burners, C for the infrared charbroiler and F for the French top.
