Wolf CG Pro Gas Knob Lights Flash: Normal Burner Start-Up Signal

What Pro gas knob lights flash means

On Wolf CG Pro gas cooktops such as the CG304P/S and CG365P/S, all knob LEDs flash momentarily when you turn a burner on. This is normal. It is the cooktop's own signal during burner start-up, not an error code. You will see the lights blink once or twice as the burner lights, and then they settle. Our technicians read the code against your model, and that matters for the repair choice.

Common causes of Pro gas knob lights flash

Normal burner start-up signal
Igniter sparking as the burner lights

✓ One safe check you can try

1. Turn one knob to light and watch the LEDs blink briefly; this is expected. 2. If the burner does not light, make sure the burner cap is seated and dry. 3. Never ignore a gas smell: leave the house and call the gas utility from outside. 4. If lights flash continuously or the burner will not light, call us.

! Why to stop there

Nothing is broken when the lights flash briefly at start-up.
A continuous flash or no ignition is a different matter, which we can inspect.
Gas work should be done by a trained technician.
A 30-day warranty on workmanship comes with every job.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.
