That removes the commonest failure on older cooktops and leaves a short list: the cap, the igniter, the port, the mixture, and the flame sensing. This job works through them in that order because that is the order of likelihood and the order of cost. ### What actually goes wrong - **A cap seated wrong after a clean.** Free to fix and easily half the calls of this kind. - **An igniter that has aged past lighting the gas.** Replaced for that burner alone. - **A blocked port.** Cleared rather than replaced, and visible as an uneven ring of flame. - **Wrong orifices after a fuel conversion.** Yellow flame across every burner rather than one. ### What decides the figure Whether a part is involved at all. A cap and a clean is the visit; one igniter is the visit plus a part; a set of orifices after a botched conversion is a longer job on a machine that has been wrong since it was installed. What this involves Cap seating checked before any part is named Igniter replaced per burner, not per cooktop Flame color and port blockage looked at properly The cap first, every time A burner cap sitting a fraction off after a clean is the commonest cause of a burner that sparks and never catches. It takes ten seconds to check and it is free. Watch it spark Whether the spark is at the right place, whether it is reaching, and whether every burner sparks when one knob is turned — which is normal on this equipment and alarms people. The igniter, if it is the igniter Replaced for the burner that has failed rather than as a set. They age individually and there is no saving in changing four. Ports, flame and the gas itself A yellow flame is a burner port or the air mixture, and on a range converted between natural gas and propane it is the orifices. That is worth knowing before parts are ordered. Sealed burners, and why the list is short A sealed burner has no open well under it, so spills do not reach the gas train.
