About this model
Model overview
About this rangetop
Dacor lists the DYRTP486SNG in the Discovery iQ series, and it is no longer sold new. It belongs with the DYRTP366SNGH, though check the labels, since the two may differ in size or features. Treat each as its own unit, identified by its own label.
Typical reasons owners call
People usually notice a burner first. It sparks but does not catch, or it catches and then goes out when you lower the knob. Next comes the control side: a knob that no longer feels connected, a clicking that continues after ignition, or a unit that behaves differently after the power flickers. These patterns separate into gas flow, spark and control logic, and each has its own tests.
Working on a rangetop built into a counter
- Gas and electrical connections run below the surface, so the cabinet beneath must be cleared.
- Knobs along the front face can hide wiring behind them.
- An island installation needs room to approach from several sides.
- Heavy burner grates are lifted off before any inspection begins.
Since the model is discontinued, a good diagnosis matters more than speed. We would rather confirm the cause than order a part that may not be needed.
Ventilation next to the burners
Professional-style rangetops often work with a large hood. If the hood draws too strongly, flames can lean or lift. If the hood is down or blocked, heat and moisture build up near the controls. The article on a noisy range hood can help you describe what you hear.
Owner checks
- Look for a tripped breaker.
- Clean cold caps and let them dry.
- Confirm the gas valve handle is parallel to its pipe.
- Try the burner with the hood off.
If you notice gas, go outside, avoid switches and call the gas utility or 911. Sparks or a burning smell mean breaker off.
Where to go next

Frequently asked questions
Yes. It is discontinued as a new product, but a technician can diagnose and repair it where parts are available.
The model number suggests nothing we can safely decode, so we confirm the fuel from the label and the connection at your home.
That depends on the fault and your kitchen. The diagnosis tells you what is wrong, and the written estimate lets you decide.
