A rangetop like the MAST366RTXE is a gas cooktop built for installation over open cabinetry or a separate wall oven, rather than a drop-in cooktop that sits over a closed cabinet — worth knowing at diagnosis time, since access to the burner valves and ignition wiring underneath depends on what’s actually installed below it rather than a fixed cabinet layout the way a standard cooktop assumes.
