The NGM5058UC was a 500 Series 30 inch gas cooktop with five sealed burners at 41,400 BTU. Discontinued Bosch gas cooktops are among the easiest appliances to keep going, because the parts that fail on them – burner caps, crowns, electrodes, grate feet and valve seals – are mechanical, standardised and still widely stocked. A gas cooktop rarely dies; it accumulates small faults until somebody decides it looks tired.
