Without gas, shut the stove's breaker off A burner you cannot turn down or off is an emergency. Cut the power at the breaker on an electric stove, or close the gas shutoff only if it is within reach without going near the flame; otherwise leave and call the gas utility or 911 from outside. Keep the stove off until the repair. ## What it usually means. On an electric coil stove each burner has a switch behind its knob that clicks the power on and off to keep the heat you chose. When the contacts inside that switch weld together, the burner gets full power all the time, and turning the knob to off may do nothing. On a glass stovetop with touch controls the same thing happens when a relay on the control board sticks closed. On a gas stove the cause is usually mechanical: a valve that no longer turns down, or a knob that spins on a worn shaft without moving the valve at all. Whatever the fuel, a burner that will not turn down or off can overheat a pan, scorch the counter beside the stove and start a fire, so the first job is to cut its heat at the source. The 5 causes, cheapest first Answer these first 01 Does the burner stay red or keep its flame even with the knob pointing at off? 02 Does the knob turn normally, spin loosely, or feel stiff and gritty? 03 Is it one burner, or more than one? 04 Is it a coil burner, a burner under smooth glass, an induction zone or a gas flame? 05 Did this start after a boil-over or after cleaning around the knobs? ## Check these before you book. Stove burner stays on high: 5 checks, and none of them costs anything. 01 Do not lean over the burner; on an electric stove, switch off the stove's breaker at the main panel and watch from a step back until the glow fades. 02 On a gas stove, if the flame will not go out with the knob, close the shutoff behind the stove only if you can reach it without leaning over the flame; if you cannot, leave the house and call the gas utility from outside. 03 Keep towels, oven mitts, paper and plastic well away from the burner until it has cooled. ### Also worth checking - Once it is off and cold, move pans away and do not switch the breaker back on to use the other burners. - When you book, tell us which burner it was and whether its knob turned normally or spun loosely. ## The causes, cheapest first. 5 things stove burner stays on high turns out to be, from knob loose on its shaft to gas valve that will not turn down. [The cost guide](https://stoverepair.center/cost/) 1. 01 lowest ### Knob loose on its shaft A cracked knob can spin without turning the switch or valve behind it, so what the knob shows is not what the burner is doing. A new knob for your model fixes it once the switch behind it has been checked. [Fixed by knob and switch replacement](https://stoverepair.center/services/knob-and-switch-replacement/) [See stove knob broken or loose](https://stoverepair.center/problems/stove-knob-broken-or-loose/) 2. 02 low to moderate ### Burner switch stuck on The contacts inside a coil burner's switch can fuse after years of clicking, often helped along by a spill running into the back panel. The switch must be replaced; the coil itself is usually fine. [Fixed by knob and switch replacement](https://stoverepair.center/services/knob-and-switch-replacement/) [On an electric stove](https://stoverepair.center/types/electric-stove-repair/) 3. 03 moderate ### Wires fused behind the control panel Heat and old insulation can let two wires behind the knobs melt together, feeding a burner power that bypasses its switch. The wires and usually the switch are replaced together.

The display may still show the zone as off. [Fixed by control board and display repair](https://stoverepair.center/services/control-board-and-display-repair/) [On an induction stove](https://stoverepair.center/types/induction-stove-repair/) 5. 05 moderate ### Gas valve that will not turn down A worn or damaged burner valve can stay wide open or refuse to close fully, leaving a tall flame at every setting. Nobody should take a gas valve apart at home.

It is safer not to. A stuck switch will run that burner at full power the moment the breaker is back on, whether you want that burner or not. ### My glass stovetop still looks hot after I turned it off. Is it stuck on? Probably not. The hot-surface light stays on until the glass cools. If the element glows red or the glass keeps getting hotter with no zone selected, treat it as stuck and switch off the breaker. ### Why does my burner only work on high? That is usually the same switch failing in a milder way: its contacts stick instead of cycling. Have it replaced before it stops turning off at all. ### Can a child's knob covers cause this? A cover that does not fit the knob can hold it at a setting or wear down the knob's insert. Use covers made for your stove and check the knob points to off when you close them. --- **[Read on the site: Stove Burner Stays on High: Causes and Fixes](https://stoverepair.center/problems/stove-burner-stays-on-high/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
