Automatic stove shut off devices

What does an automatic stove shut off device do?

It watches for a sign of trouble, such as an empty kitchen, a timer running out or a smoke alarm. Then it cuts power or gas to the stove. To cook again, you reset it or turn the burner back on yourself. Most sit between the stove and its outlet or gas line. A few replace the stove’s knobs instead. Some people call this a stove auto shut off.

The problem they target is real. NFPA says unattended equipment is a factor in 25 percent of reported home cooking fires. It is a factor in half the deaths from those fires. Ranges and cooktops account for 51 percent of home cooking fires. All three are 2020 to 2024 averages. Source: NFPA.

What types of stove shut off device are there?

There are five common types. They differ in what they cut, what makes them act and how hard they are to install.

1. Plug-in power cut-off for electric ranges

A box plugs into the range outlet, and the range plugs into the box. When it decides to act, it cuts power to the burners. No electrician is needed if your range has a plug. Check whether it is a 3-prong or 4-prong plug before you order.

• · Prices: FireAvert lists its Auto Stove Shutoff at $249.99. It cuts power if your smoke alarm keeps sounding. iGuard lists its plug-in electric model at $549 plus shipping in the U.S. It acts when it senses that you have left the kitchen.
• · Good for: electric ranges with a plug, renters, and cooks who may not respond to an alert.
• · Drawbacks: no help for a gas stove. A hard-wired cooktop needs a different model. A smoke-alarm unit acts only once there is smoke, so the food is already burning.

2. Gas valve shut-off kits

These add an automatic valve to the gas line behind the stove. When the device acts, the valve closes and the flames go out. iGuard says its gas model requires a certified gas plumber, and lists it as coming in 2027. FireAvert sells a gas version at the same $249.99 and calls the install plug-and-play. Either way, have a licensed plumber connect it and test for leaks.

• · Good for: gas stoves where the cook may not respond to an alert.
• · Drawbacks: the plumber adds to the cost. Renters will usually need the landlord's permission. There must be room for the valve behind the stove.

3. Timers

A timer turns the burner off after a set time, whether or not anyone is there. Ome Smart Knobs replace your stove knobs and work with gas and electric stoves. Ome says each knob ships with a 15-minute default. If a burner stays on longer, it turns the stove off and sends a notification. Ome lists $129 for one knob and $479 for four. Every pack size was listed as unavailable when we checked.

• · Good for: busy cooks who forget a pot and want a hard stop.
• · Drawbacks: a timer cannot tell whether you are standing at the stove. It can cut a long simmer, and it does nothing if it is set too long. Replacement knobs only fit stoves whose knobs come off.

4. Motion-based shut-off

A motion or presence sensor watches the kitchen. If it sees no one for a set time while a burner is on, it cuts the power or gas. iGuard works this way. Its app can set a master lock and a schedule for when the stove works. iGuard includes the first year of the app free. CookStop makes a device for electric stoves that turns the stove off once it has been left unattended for a set time.

• · Good for: cooks who wander off mid-meal, including people with memory loss.
• · Drawbacks: it can cut power while you are still nearby if the sensor misses you. Most models are for electric stoves.

5. Alert-only monitors

These watch the stove and warn you, but never touch the power or gas. Stovyn, which we make, is one of them. The cook, or someone they trust, still has to turn the burner off. Our comparison of stove safety devices covers other options side by side.

• · Good for: cooks who will respond, gas stoves, rentals and long simmers.
• · Drawbacks: if nobody responds, the burner stays on.

How much does a stove shut off device cost?

Listed prices we checked in October 2026: FireAvert, $249.99 for electric or gas. iGuard, $549 plus shipping for its U.S. plug-in electric model. Ome Smart Knobs, $129 for one or $479 for four, listed as unavailable. A gas valve kit also needs a plumber, which adds to the cost.

Prices and stock change often, so check the maker's page before you buy. Several products we looked at were sold out or not yet on sale.

What is the best automatic stove shut off device for elderly people?

It depends on whether the person will notice and act on an alert. For someone with dementia or serious memory loss, a shut-off device is the safer choice. It works without them. The Alzheimer’s Association advises using appliances with an automatic shut-off feature. For a parent who still cooks well but sometimes forgets, an alert that also reaches family may be enough.

The Alzheimer's Association also suggests knob covers, removing the knobs or turning off the gas when the stove is not in use. A shut-off device keeps the stove usable while adding a backstop.

A few practical points for families. Pick a model your parent cannot easily switch off. Check the stove type and plug before you buy. Then test it together while they cook. Our guide to stove safety for elderly parents covers the rest.

How does a gas stove automatic shut off valve work?

An automatic valve is added to the gas supply behind the stove. When the control unit decides cooking has been left alone, the valve closes and the flames go out. Because the work is on the gas line, plan on a licensed plumber and a leak test. iGuard says its gas model requires a certified gas plumber.

Can you put a shut off timer on an electric stove?

Yes, in a few ways. Smart replacement knobs such as Ome add a timer that turns the burner off, if your knobs come off. Plug-in units such as iGuard include an extended cooking timer. Many ovens already have a timer built in. GE says most modern ranges shut the oven off after 12 hours. That covers the oven, not the burners.

GE's note on this is in its Sabbath mode press release. Some newer cooktops go further. Bosch lists an automatic safety shut-off on its 800 Series induction cooktop. Check your manual to see what yours does. iGuard's timer is described on its product overview.

Do building codes require a stove shut off device?

Under the model codes, not in a typical house or apartment. They call for cooktop fire protection only in certain buildings, such as assisted living, nursing care and college dormitories. There, cooktops need either a hood fire-suppression system or burners listed to keep cooking oil from igniting. Your state or city decides which code edition applies and can add its own rules.

The details sit in Section 904 of the International Fire Code and International Building Code. The 2018 International Fire Code requires protection for household-style cooking appliances in care facilities. The 2024 International Building Code text gives two routes. One is a hood with an automatic fire-extinguishing system listed to UL 300A. The other is burners tested and listed to keep cooking oil from igniting at maximum heat for 30 minutes. Ask your local fire marshal or building department whether a given product qualifies.

Separately, UL 858, the U.S. safety standard for household electric ranges, added a cooking oil ignition test for coil cooktops. Intertek, a testing lab, lists April 4, 2019 as the effective date. NIST describes one way to pass: a dry pan on the highest setting must stay below 385°C (725°F) for 30 minutes. NIST notes that stoves built for this commonly use a heat-sensing switch that cuts the power. The test covers coil elements only. It does nothing for gas burners or a stove you already own.

Should you get a shut-off device or an alert-only monitor?

A shut-off device is the better choice when:

• · The cook has dementia or memory loss and may not notice an alert.
• · The cook lives alone and nobody nearby could respond in time.
• · Burners have been left on before, even with reminders in place.
• · A care plan or a care team calls for one.

An alert-only monitor may be enough when:

• · The cook can respond and mostly needs a reminder.
• · You have a gas stove and do not want plumbing work.
• · You rent and cannot change the gas line or the outlet.
• · You cook long simmers that a motion sensor or timer might cut short.

Some families use both. Neither replaces good habits, which our stove fire prevention guide lists. If a pan ever does catch fire, here is how to put out a grease fire.
