They are told apart by what the burner does rather than by what it fails to do, which is why the first questions on the phone are about clicking, smell and how recently it was cleaned. ### Dual-stacked burners, and what they add The professional ranges and rangetops on this make use burners with two rings of flame stacked one above the other under a single grate, so one position can sear and also genuinely simmer. That is why they cook well and it is why they have more to go wrong: two gas paths, two sets of ports, and a control that has to manage both. A range where the high flame is perfect and the simmer will not hold has one specific problem, not a general one. ### What we are called out for - **Caps and ports**, which is the free half of this work. - **Igniter electrodes and the spark module**, which serve several burners at once — so all of them misbehaving together is one part, not six. - **Flame sensing**, which is what a burner that lights and drops out is telling you about. - **Valves and the simmer stage** on dual-stacked burners. - **The grill and griddle zones**, which are separate circuits and have their own page. ### What it costs From $185, which is one igniter on one burner. A real share of these calls are a cap seated wrong and cost the visit only. The exact cost is confirmed after the diagnostic and agreed before anything is opened. What this involves Cap seating and port cleaning before any part Spark, sensing and gas told apart rather than lumped together Each stage of a dual-stacked burner proved separately Which burner and which stage One burner or all of them, and on a dual-stacked burner the high flame, the low flame or both. Those answers split this job into four very different searches before anybody kneels down. The free half Caps lifted, seated squarely, ports cleared. A burner cap put back a fraction out of place after a cleaning is one of the most common reasons one of these ranges misbehaves, and it costs the visit only. Spark, sensing, gas A burner that clicks without lighting, one that lights and goes out, and one that does nothing are three circuits. Flame-sensing re-ignition means the range is watching the flame and will spark again if it thinks it has gone — which is normal behavior with a boiling pot and a symptom without one. Prove every position Every burner is lit, taken to simmer and held before the appointment ends, because a range with six positions has six chances to be half right.

Not necessarily a problem. These burners use flame-sensing re-ignition and will spark again if they think the flame has gone — a pot boiling over, a draft from an open slider, or a cap sitting a fraction proud will all do it. Take the pot off, let it cool, lift the cap and reseat it squarely. If it still clicks with a clean dry cap and a steady flame, it is the sensing side rather than the ignition side. ### The simmer will not stay lit but the high flame is perfect. That is specific to a dual-stacked burner and it is genuinely useful information. There are two rings of flame under that grate with two gas paths and two sets of ports. A low stage that will not hold while the high one is faultless is a different diagnosis from a burner that is simply out, and telling us which you have shortens the visit. ### Can I clean the burners myself? Yes, and it is worth doing. Caps and heads lift off, wash, dry completely, and go back one way round only — the alignment matters and it is what people get wrong. Do not poke the ports with anything metal. If it misbehaves right after a clean, the cap is the first suspect and it costs nothing to check. ### Is the smell of gas ever normal? A brief whiff at ignition, yes. Anything you can smell in the room with the range off, no — turn off the supply, leave the house and call the gas company before anybody else. That is not a service call, it is an emergency, and we would rather lose the booking. --- **[Read full article: Range burner & ignition repair](https://jennairmiami.support/services/range-burner-and-ignition-repair/)**
