Care for cast grates on a legacy DCS cooktop or rangetop by hand washing, drying fully and oiling lightly. Avoid the dishwasher, which causes rust and finish loss.

When one burner on a DCS cooktop won’t light but the others work, the cause is local to that burner. Check the cap, the igniter and the knob first.

An RGT griddle that heats unevenly is usually caused by clogged burner ports, a warped plate or a backed-up grease trough. Check them in this order.

The CTD-365 is the 36-inch, five-burner drop-in from the same DCS brochure. Its sealed surface keeps spills out of the burner box, but liquid that finds its way under a cap can still short the ignitor wiring and cause constant clicking. If the simmer is too hot on low, the burner’s low setting needs adjustment […]

The CDU-304 is a later DCS drop-in cooktop, from the DCS by Fisher & Paykel era. After cleaning, burner heads and caps must go back exactly as they came off; a head turned slightly out of line stops the spark reaching the gas. If no burner sparks at all, the spark module or its power […]

The C-24W is DCS’s professional wok cooktop, a single high-output burner built to heat a wok quickly. Because the burner runs very hot, its ignition parts and ring wear faster than on a regular cooktop. A flame that roars or lifts off the burner needs air and gas adjustment by a licensed technician.

The CT-304 uses DCS’s sealed Dual Flow Burners, which DCS advertised as dropping the main flame at the lowest settings and keeping only an inner simmer flame. When that inner flame will not light or keep burning, the burner’s small inner ports are blocked or the cap is off center. A 30-inch drop-in with four […]

The CT-365 is the 36-inch five-burner drop-in cooktop. Its center burner is often used hardest, and a flame that lifts off the burner or roars points to a gas adjustment issue for a licensed technician. Wobbling grates usually have worn cushion supports under the grate feet.

The CTD-304 appears in DCS brochures from Fall 2006 and Summer 2008 as the 30-inch, four-burner drop-in. Its platform grates have high-temperature cushion supports so pans slide easily; when those wear, grates scratch the top. Metal knobs get warm with large pots on the front burners; that is expected, but hot knobs with small pans […]

The CPV-364GD is a professional rangetop: burners and a griddle with front controls, built into the counter with no oven below. DCS calls these “professional cooktops” in its guides. The griddle has its own thermostat, so a griddle that swings from too hot to too cool is diagnosed separately from the burners. Boil-overs are the […]
