This 36-inch gas cooktop turns up in kitchens where the owner wanted real knobs under the hand instead of a glass touch panel. With sealed burners and no control board to speak of, it ages differently from Thermador’s induction cooktops, and the trouble tends to be physical: wear at the spark igniter, crust in the burner ports, or a gas valve that no longer meters the flame evenly.
When a call comes in, we start by watching how the burner behaves. Clicking without ignition sends us to the igniter and electrode first, a ragged or lazy flame sends us to the ports and the cap seating, and a flame that fades after lighting points toward the valve. No error code is involved, because nothing on this cooktop displays one.
One caution on identification: this model number was read from product-page image data instead of listed in body text. Check the rating plate under the cooktop before any model-specific part is ordered.
No. With mechanical knobs there is no display to report one, so diagnosis comes from watching the ignition and flame directly and from checking the igniter, ports and valve in that order.
Look for the rating plate on the underside of the cooktop body, or in the purchase paperwork. Matching it before parts are ordered avoids a wrong-part delay, especially on a model whose listing is only lightly documented.
Repeated sparking with no flame means gas may be reaching the burner unlit, so turn the knob off and ventilate the room. If you smell gas, close the shutoff valve and call us before trying again.
