RT484DG

Most common issues on this model

1. Burner ignition is slow or inconsistent
2. Burner goes out at the lowest setting
3. Turning the knob gives no click and no flame
4. The dual griddle does not respond to its control
5. Gas smell that will not clear, handled as safety work first

The RT484DG is a 48-inch legacy gas rangetop that sits in a counter cut-out, with a cabinet or a separate wall oven underneath it. Production ran 2002–2011, so most of these now have years of daily use behind them.

Grease collects around the dual griddle more than anywhere else on the top, so we clean and inspect that burner area as part of the work. The ignition parts live close to the heat and to spills, so they age faster than anything else on the top. Each burner here has its own spark module, electrode and valve micro-switch, so a single dead burner usually points to that burner’s own set.

We start with the simplest checks, cleaning and reseating burner parts, so you only pay for parts that are really needed. Our process is simple: a written price, your go-ahead, the repair, then 30 days of workmanship coverage.
