--- title: "Cooktop Problems — Symptoms and What They Mean" description: "Every cooktop symptom we are called out for, from a burner that will not catch to an induction zone that ignores the pan, what each tends to mean, and its…" url: "https://cooktoprepair.center/problems/" --- Start with the symptom # Cooktop problems, symptom first. Every symptom we are called out for, traced to the causes that actually explain it — cheapest first. Start from what you are seeing rather than from what you think is broken. ## Needs a visit now A cooktop that gives off a gas smell, sends up smoke or a hot-plastic smell from under the counter, keeps a burner or zone heating after the control says off, has a crack running through its glass, or drops the breaker the moment a zone comes on is a hazard set right into the counter, so these problems come first — each with its usual causes, the cheapest first. With an electric or induction top, switch its breaker off and keep hands and pans away from broken glass. With gas in the air, leave every switch, lighter and phone alone inside: get everyone out, then phone the gas utility from the street. [Book a visit](https://cooktoprepair.center/schedule/) Gas, fire, broken glass or live current ### [Cooktop Gas Smell](https://cooktoprepair.center/problems/cooktop-gas-smell/) A rotten-egg or sulfur odor rises from the cooktop, from the seam where it meets the counter, or from the cabinet doors underneath, whether a burner is lit or not. Causes, cheapest first 1. Seeping joint at the regulator or connector under the counter *varies* 2. Knob valve that no longer seals *moderate* 3. Flame snuffed out while the knob stayed on *low* [All 5 causes and what to check](https://cooktoprepair.center/problems/cooktop-gas-smell/) Gas, fire, broken glass or live current ### [Cooktop Burning Smell](https://cooktoprepair.center/problems/cooktop-burning-smell/) A hot, electrical, plastic or scorched odor comes from the cooking surface, the knobs, the downdraft grille or the cabinet under the counter. Causes, cheapest first 1. Spill charring under a cap, in a drip bowl or on the glass *no repair* 2. Browned wire in the junction box under the counter *moderate* 3. Coil receptacle overheating *low* [All 6 causes and what to check](https://cooktoprepair.center/problems/cooktop-burning-smell/) Gas, fire, broken glass or live current ### [Cooktop Burner or Element Won't Turn Off](https://cooktoprepair.center/problems/burner-or-element-wont-turn-off/) A gas flame keeps burning, a coil or radiant ring stays red, or an induction zone keeps heating after its knob or key has been set to off. Causes, cheapest first 1. Infinite switch contacts welded shut *low to moderate* 2. Knob stripped on its stem *low* 3. Gas valve not seating at off *moderate* [All 6 causes and what to check](https://cooktoprepair.center/problems/burner-or-element-wont-turn-off/) Gas, fire, broken glass or live current ### [Glass Cooktop Cracked](https://cooktoprepair.center/problems/glass-cooktop-cracked/) A line, a star-shaped break or a chipped edge has appeared in the glass-ceramic top of a radiant or induction cooktop. Causes, cheapest first 1. Impact from a dropped pot, lid or jar *moderate to highest* 2. Thermal shock from a pan boiled dry *moderate to highest* 3. Pressure from a tight counter cutout *varies* [All 6 causes and what to check](https://cooktoprepair.center/problems/glass-cooktop-cracked/) Gas, fire, broken glass or live current ### [Cooktop Tripping Breaker](https://cooktoprepair.center/problems/cooktop-tripping-breaker/) The circuit breaker for the cooktop trips as a burner or zone switches on, at one particular setting, or a few minutes into cooking. Causes, cheapest first 1. Coil element or receptacle shorting *low* 2. Radiant element shorting beneath the glass *low to moderate* 3. Burned connection in the cabinet junction box *moderate* [All 6 causes and what to check](https://cooktoprepair.center/problems/cooktop-tripping-breaker/) ## Everything else we are called out for Nothing below involves a gas smell, smoke, broken glass or a zone that refuses to switch off, so these can wait for a booked visit. Each page lists the safe checks worth making before a technician arrives. [The repairs behind them](https://cooktoprepair.center/services/) ### Cooktop Burner Won't Light The igniter clicks but the gas never catches, the burner lights only after several tries, or nothing happens at all when the knob is turned. 6 causes ### Cooktop Igniter Keeps Clicking The spark keeps ticking after the burner has lit, ticks with every knob off, or every burner clicks together whenever one is turned. 5 causes ### Cooktop Flame Yellow or Uneven Burner flames are yellow or orange, lift off the ports, burn high on one side and low on the other, or leave soot on pan bottoms. 6 causes ### Cooktop Element Not Heating A coil stays black, a radiant ring under the glass never glows, or a zone warms so weakly that a pot of water will not boil. 6 causes ### Cooktop Element Only Heats on High An element works at full power but does nothing at medium or low, or it jumps between full heat and none with nothing in between. 5 causes ### Cooktop Simmer Too Hot The lowest setting still boils sauces, scorches rice, or will not hold a gentle simmer on a gas burner or an electric element. 5 causes ### Induction Cooktop Not Detecting Pan An induction zone flashes a pan symbol, beeps, or switches itself off even though a pot is sitting squarely on it. 6 causes ### Induction Cooktop Buzzing or Clicking An induction cooktop hums, buzzes, whines or clicks while cooking, louder with some pans than with others. 5 causes ### Cooktop Controls Unresponsive Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element. 5 causes ### Cooktop Hot Surface Light Stays On The hot surface light or residual heat indicator stays lit long after the glass has cooled, or it never comes on at all. 5 causes ### Cooktop Fan Runs Constantly The cooling fan under an induction or touch-control cooktop keeps running long after cooking, or a downdraft blower will not shut off or retract. 6 causes ### Cooktop Error Code Characters or a blinking symbol appear on the cooktop display, it beeps, and a zone, or the entire cooking surface, stops working. 6 causes ## Not every cooktop breaks the same way. A gas cooktop sparks its burners alight, an electric one heats coils or ribbon elements under smooth glass, an induction top warms the pan itself through a magnetic field, and a pro-style rangetop brings heavy gas burners and front knobs to a base cabinet. Find the one in your counter. [All cooktop types](https://cooktoprepair.center/types/) ### Gas cooktop A gas cooking surface dropped into a countertop cutout, with its gas line and power cord running down into the cabinet underneath. ### Electric cooktop A coil or smooth-glass radiant cooking surface built into the countertop and wired to its own circuit in the cabinet or wall behind it. ### Induction cooktop A glass cooktop in the counter that heats the pan itself through magnetic coils, run by power boards and cooled by a fan underneath. ### Rangetop A pro-style gas cooking top with its knobs across the front, set into a notch above a base cabinet, often with a griddle or char-broiler beside the burners.

These are the jobs a visit usually turns out to be. [All 10 repairs](https://cooktoprepair.center/services/) diagnostic ### Diagnostic visit A visit that runs every burner or zone on the cooktop, looks under it from the cabinet below and names the failed part before anything is ordered. low ### Burner and igniter repair Gas cooktop and rangetop burners that will not light, light late or burn with a ragged flame, traced to the electrode, the burner head, the cap or the ports. low to moderate ### Spark module and gas valve repair The parts deeper in a gas cooktop: the spark module that fires the electrodes, the switches on the valve stems, the valves that meter the flame and the regulator. low to moderate ### Radiant element repair Zones under a smooth glass cooktop that stay dark, heat weakly or cut out, traced to the ribbon element, its limiter or the relay that feeds it. moderate to highest ### Glass top replacement A new glass-ceramic surface for a radiant, induction or gas-on-glass cooktop that has cracked, chipped at the edge or been pitted beyond cleaning. lowest ### Coil element and receptacle repair Coil elements on an electric cooktop that stay cold, spark at the plug or heat unevenly, along with the receptacles, drip bowls and wiring they plug into. moderate to highest ### Induction board and coil repair Induction zones that stop sensing pans, cut out, buzz or show codes, traced to the power boards, the coils, their sensors and the links to the controls. moderate ### Touch control repair Glass touch keys and sliders that ignore a finger, start zones by themselves or stay locked, traced to the keys, the control board or the lock setting. low ### Infinite switch and knob repair Knob-controlled cooktop zones that heat only on high, will not simmer or will not switch off, and the worn knobs and switches behind them. low to moderate ### Cooling fan and downdraft repair The fan that cools an induction or touch-control cooktop's boards, and the downdraft vent that rises behind the cooking surface or pulls air down between the burners. For the heart of your home. ## Questions about the problems. ### My cooktop has a problem that is not listed. Will you still come? Yes. Only the most frequent cooktop complaints have pages; many rarer ones reach us too. Describe the flame, the glow, the sound or the smell in the booking notes, and that becomes the starting point on site. ### The cooktop shows two of these problems. Which should I read first? Begin with whichever appeared first, since the second often follows from it: an igniter that keeps ticking after a spill is often the one that later will not light at all. Each problem page links to the problems it tends to arrive with. ### Which cooktop problems are emergencies? A smell of gas, smoke or a hot-plastic smell, a burner or zone that will not switch off, a crack or chip in the glass, and a breaker that drops when a zone comes on. Each page states how urgent its problem is. A slow boil, a knob that feels loose or a hot-surface light that lingers can wait for a booked visit. ### Can I keep cooking on the working burners until the visit? Only on burners or zones that still behave normally, with no gas or burning smell and a control that still shuts them off. Never cook on cracked glass. If you smell gas, get out and call the gas utility from outside; for an electrical problem, switch the cooktop off at its breaker. --- **[Read on the site: Cooktop Problems — Symptoms and What They Mean](https://cooktoprepair.center/problems/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
