RT484F

Most common issues on this model

1. Burner needs repeated attempts before the flame catches
2. Flame that pulses or lifts when you turn it down
3. Valve stem turns but the burner stays cold
4. No heat from the French top even with the knob on
5. Faint but lasting gas smell by the cooktop, which is a safety job first

The RT484F spans 48-inch of countertop, and in most kitchens it is built into an island or a perimeter run under a vent hood. Built in the 2002–2011 range of years, it is old enough that we check wiring and connectors on every visit.

Because the French top runs separately from the open burners, we test it on its own instead of assuming the whole top is affected. Low flame performance suffers first as parts age, so a burner that was fine on high may struggle at the lowest setting. With a micro-switch at each valve, a burner that keeps sparking can come from the switch side as easily as from the electrode.

Our starting point is the ignition circuit, since a clicking burner and a silent one lead to different parts. You get a written price before we begin, and our work carries a 30-day workmanship warranty.
