- Oven temperature accuracy
- Burner cap and grate fit
The RDU-366 is a 36-inch dual fuel range with six gas burners and an electric oven. With no griddle or grill, the whole cooktop is burners, which makes it a popular choice for home cooks who want every position available for pots and pans.
With six burners the first job is to test each one: does it light on the first try, does it hold a steady blue flame, and does it respond across low to high. A burner that clicks but does not light often comes down to a dirty port, a misplaced cap or a weak igniter. We then move to the oven, where we check bake and broil heat and compare the actual temperature with the dial setting.
This range is from the DCS Professional line and is an older model in many homes. We say plainly that some parts are scarce, confirm them before the repair, and give you a written price. Gas line work beyond the appliance goes to a licensed plumber. Before ordering anything we read the model and serial number from the label.

Error codes this model can show
One burner on my RDU-366 clicks but never lights. Why?
It is often a dirty burner port, a cap that is not seated, or a worn igniter. We clean and test it first so you only pay for a part if it is actually needed.
What is the difference between six burners and a griddle model?
The 366 has six burners across the top, while the griddle versions swap two positions for a flat cooking surface. Service checks differ because griddles add their own burner and control.
Will you tell me if my range is not worth fixing?
Yes. We give a written price before work begins, and if the repair costs too much for the range, we say so directly. Some parts for this older line are hard to find, which is why we confirm them before starting.
