I have a 13 or 14 year old Miele gas cooktop. It's just burners. My oven is an electric built in.I haven't seen these gas ranges with an auto re-ignition system. Are they found on new or older gas ranges??
The Miele cook top is a very solid unit. The burners all feature electronic ignition. I can blow the flame out on a buner on low with just with my lung power. Almost instantly, tap tap tap and the unit will relight itself. If it doesn't, the unit will cut the gas flow.
I can also light the unit with a match should the electronic ignition fail. Turn the control knob on, press down to manually bypass the safety protocols and the gas will flow. Bring the light up to the burner and ignite the gas. Hold the knob down for a few seconds and then release. If the burner fails to remain lit, the unit cuts the gas.
