A gas smell near a cooktop or rangetop is not a troubleshooting moment. The steps below come before any call to a repair company, not after.

A single lazy, yellow-tipped flame on an otherwise normal cooktop is one of the most common calls we get, and usually one of the least expensive to fix.

Dacor’s DTT48M876 spreads its Pro burners across 48 inches. On LP homes, flames that are too tall and lazy usually mean the rangetop was not converted, or the regulator was not set for propane. Valve stiffness is serviced, not lubricated by the owner; sprays can damage the valve seals.

The DYCT365G came in black, stainless and white variants. A burner that lights and then goes out when the knob is released is the most common complaint, and on many cooktops that points at the burner’s flame safety or the gas supply rather than the igniter. We check gas pressure and the burner assembly before […]

The DTT48M976 pairs six burners with a 1,400-watt electric griddle, all on a 120-volt, 15-amp supply. A griddle that stays cold while the burners work is diagnosed at the griddle element and its control. Grease finds its way around griddles over time, and we check the surrounding wiring while the griddle is out.

The DTCT365G is the 36-inch Distinctive gas cooktop. Burner caps that have been overheated or dropped can warp slightly, and a warped cap gives a lopsided flame that looks like a valve problem. We check caps first because they are the cheapest fix.

Two 22,000 BTU burners make the DTT36T960G one of the stronger 36-inch Dacor rangetops. High-output burners tolerate little debris in their ports, and a flame that is short on one side is usually a cleaning issue. Its user guide covers burner care in detail, and following it prevents many service calls.

The DTCT466G is the widest cooktop in the Distinctive DTCT line. Many burner switches feeding one spark module mean that a worn switch shows up as clicking across the whole cooktop. Chipped grates are replaced for safety, since sharp edges and unstable pans are a hazard.

The DTT48T960G is the 48-inch Transitional rangetop. When several burners click together without being turned on, a burner switch behind one knob has usually stuck and is energizing the shared spark module. That is a small repair once the knob that causes it is found.

The RNCT365G is the knob-controlled Renaissance gas cooktop, distinct from the electronic touch-control RNTT365GB. Without electronics, its repairs center on igniters, switches, valves and burner parts. Staining on the top is cleaning, not repair, and the manual lists cleaners that are safe for the finish.
