Automatic stove shutoff devices: what exists and what needs a professional
Updated
Some devices cut power or gas to a stove when no one is in the kitchen, but electric ranges and gas lines call for a licensed installer. Compare the types, their limits and cheaper steps first.

Why people want a stove shutoff
Cooking is the leading cause of home fires and home fire injuries, according to the U.S. Fire Administration. In 2021 fire departments responded to an estimated 170,000 home cooking fires, with about 135 deaths and 3,000 injuries, and unattended equipment was the leading factor in ignition (37% of nonconfined cooking fires). For an older adult who sometimes forgets a burner, a device that turns it off can add a layer of protection. It reduces the chance of a fire; it cannot remove it.
Do not use a smart plug on a range
Electric ranges use a 240 V circuit and draw far more than the 15 A / 1,800 W rating of a typical smart plug. A smart plug on a range is a fire risk and cannot work. Smart plugs have a place only for small 120 V appliances within their rating, such as a coffee maker, and only if the appliance is meant to be switched on and off that way.
Types of stove shutoff devices
| Type | How it works | Who installs it | Typical cost | Main limits |
|---|---|---|---|---|
| Sensor-based cutoff for electric ranges | A sensor above the range detects motion or heat; if no one is present, it warns and then cuts power to the range | Licensed electrician (240 V circuit, may require a permit) | Roughly $200–$600 for equipment plus labor | Must be compatible with your range; false triggers and nuisance shutoffs possible |
| Timer-based cutoff | A timer on the range circuit cuts power after a set time unless reset | Licensed electrician | Roughly $150–$500 installed or more | Cooks need to reset it; dementia or confusion can make it frustrating |
| Automatic gas shutoff valve | A valve on the gas line closes on a signal from a sensor, timer or alarm | Licensed plumber or gas fitter; utility may need to be involved | Roughly $300–$1,000 or more installed | Gas work is never DIY; leaks and pilot lights need a professional |
| Cooktop with built-in auto-off | Newer induction and electric cooktops can include timers or automatic shutoff | Appliance installer | Cost of a new cooktop or range | Features vary by model; check the manual |
| Knob covers or removable knobs | Physically prevent use when no one should cook | You | $10–$40 | Not for people who still cook; no protection while in use |
Prices vary widely by region and installer; get at least two quotes and confirm that the device and installation meet local code. Cost ranges are rough estimates, not quotes.
Electric stove: what a pro will check
- The range’s make, model and circuit (typically a 240 V circuit and a dedicated breaker).
- Whether the shutoff device is rated for the load and listed by a recognized testing laboratory.
- Where the sensor will be mounted so it sees the cooking area but not other rooms.
- How the device warns before shutting off (beep or light) and how someone resets it.
- Whether a permit is required where you live. Ask the installer; rules vary by city and county.
Always turn off the breaker for any electrical work and hire a licensed electrician if you are unsure.
Gas stove: licensed professional only
An automatic shutoff valve on a gas supply line changes how gas reaches your home’s appliances. It requires a licensed plumber or gas fitter, and in some places the gas utility. If you smell gas, leave the house, then call the gas utility or 911 from outside. Also install carbon monoxide alarms on every level and near sleeping areas, as the CPSC recommends (see CO detector placement).
Cheaper steps that work alongside a shutoff
- Stay in the kitchen while cooking, and turn the burner off if you leave, as the USFA advises.
- Use a kitchen timer or a voice timer. “Set a timer for 20 minutes” on a smart speaker is easy; see smart speakers for older adults.
- Keep a smoke alarm about 10 feet from the stove, and use a heat alarm if smoke from cooking causes false alarms. Read more in smoke alarm near the kitchen.
- Switch to appliances with auto-off: kettles, rice cookers, microwaves, toaster ovens and induction cooktops with timers.
- Keep pot handles toward the back and anything that can burn away from the burners.
Renters and limits
A shutoff device is a change to the electrical system or gas line, so ask the landlord first and get approval in writing. Do not install anything that disables the range’s own safety features. These devices can fail or be switched off, so test them as the maker instructs, and treat the system as a backup to attention in the kitchen, never a replacement. If the cook is regularly forgetting to turn things off, talk to their doctor; a device is not a solution to a memory problem.

Can I put my stove on a smart plug?
No. Electric ranges use a 240 V circuit and draw far more than the 15 A / 1,800 W rating of a typical smart plug, and gas ranges do not plug into outlets that way. Smart plugs are for small 120 V appliances.
Do automatic stove shutoff devices work on gas stoves?
Yes, as a gas shutoff valve installed by a licensed professional, usually connected to a sensor or timer. Gas work is not a DIY job.
Will a shutoff device stop every kitchen fire?
No. It can cut power or gas when the stove is left on, but it cannot stop a grease fire in progress or a fire from other causes. Keep a working smoke alarm and stay in the kitchen when cooking.
Can renters install a stove shutoff?
Only with the landlord’s written approval, since it changes the range’s wiring or the gas line. A plug-in kitchen timer and a heat alarm need no installation.
