The heavy cast grates on a DCS cooktop or rangetop hold up for decades with the right care, but the wrong cleaning routine shortens their life and can eventually affect how evenly pots sit and heat.

When a single burner on a legacy DCS CT, CS or CP cooktop stops working while the others are fine, the cause is almost always specific to that one burner’s own hardware.

On DCS RGT rangetops built with an integrated griddle section, uneven heat is checked at the burner beneath the plate before the griddle plate itself is suspected.

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 CS-364GL is the rangetop version of the RGS range family, with four burners and a grill. Because DCS put both products in the same guide, cooktop parts often match those of the RGS-364GL range. Cracked radiants over the grill burner cause flare-ups and uneven heat.

The CS-366 is a six-burner rangetop in the CS series. Sparking on every burner when one is turned on is normal on many ranges; sparking that continues after the flame is lit is not, and usually points to moisture or a failing spark switch. An unstable low flame calls for a licensed technician to check […]

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.
