The PRD486WDHU is a 48-inch Pro Harmony® dual-fuel range combining 6 Star burners and a built-in griddle over two separate oven cavities (a larger 4.4 cu. ft. and a smaller 2.4 cu. ft.), for 6.8 cu. ft. of total capacity. Because it has two independent ovens, a problem affecting only one cavity is useful diagnostic information — it usually isolates the problem to that cavity’s own heating element, sensor, or door-lock circuit rather than the shared control board.
The griddle section runs off its own burner and is diagnosed the same way as the other Star burners — worn igniter or clogged port first, gas-valve issue if that doesn’t resolve it.
