Stove safety buyer's guide

Stove knob covers and locks

Stove knob covers are clear plastic caps that fit over the front knobs of a range. They make it harder for a child, a pet or an adult with dementia to turn a burner on. Most fit front-facing gas and electric knobs. A 5-pack ran $7.75 to $13.99 in listings we checked. Touch-control induction cooktops use a built-in lock instead.

What do stove knob covers do?

A cover blocks the knob so a quick twist or a bump cannot turn it. Most have a hinged lid. An adult opens the lid, turns the knob and closes it again. The clear plastic lets you see whether a burner is on. A cover does not turn anything off. If a burner is already on, the cover does nothing about it.

Bumped knobs are a real cause of fires, not only a toddler problem. CPSC recall notices say the front-mounted knobs on some ranges can be turned on by accidental contact from people or pets. Samsung reported over 300 such cases and about 250 fires before its 2024 recall of about 1.1 million ranges. Source: CPSC.

What types of stove knob covers and locks are there?

There are five common options. They differ in who they stop, how they attach and what they cost.

1. Clear flip-top covers

This is the most common kind. You pull each knob off, fit the cover's base around the knob's post and push the knob back on. To cook, you open the lid. One maker's instructions say to press both sides of the cover and lift. The listings we checked attach without glue.

· Good for: toddlers, pets, and anyone who might bump a knob.
· Drawbacks: older children learn to open them. Any adult can open them by design.

2. Locking covers, sold as stove knob locks

These use a stiffer release than a simple flip lid. Some listings describe a two-point "double key" squeeze. They are still made to stop children. Before you buy one for an adult, check how it opens. If any grown-up can open it in a few seconds, it will not stop an adult who wants to cook.

· Good for: curious children who have learned to open flip lids.
· Drawbacks: harder for the household cook too. We could not confirm a stable price, so none is listed here.

3. Taking the knobs off

On many ranges the knobs pull straight off their posts. The Alzheimer's Association lists removing knobs as one way to prevent unsafe stove use. Keep them somewhere the household cook can find them.

· Good for: a stove that should not be used at all for a while.
· Drawbacks: knobs get lost, and everyone who cooks has to put them back each time.

4. One-piece knob guards

A single clear panel covers the whole row of knobs instead of one cap per knob. One maker's guard holds on with magnets and fits control panels that a magnet sticks to.

· Good for: rows of knobs that are too close together for single covers.
· Drawbacks: the panel must be magnetic, and the guard has to come off each time you cook.

5. The stove's own control lock

Some stoves have a lock built in. KitchenAid says its Control Lock stops the surface cooking areas from being turned on by the touch controls. Frigidaire says the Child Lock on its induction cooktop stops wandering hands from turning on any cooking zone.

· Good for: touch-control cooktops, and any range that has the feature.
· Drawbacks: anyone who knows the key press can turn it off. It only works if you set it each time.

Do stove knob covers fit gas, electric and induction stoves?

Covers are made for knobs on the front of a gas or electric range. One maker says its covers fit most front-facing stove knobs. Many induction cooktops have touch controls, so there is no knob to cover. For those, use the cooktop’s own Child Lock or Control Lock. Some electric ranges with knobs have a lock setting too.

· Gas range with front knobs. Most covers fit. A gas knob turned by accident can let gas out, which is why a cover is worth having here. KitchenAid tells owners who smell gas with the cooktop off to check that no burner was turned on by accident.
· Electric range with front knobs. Most covers fit. Some also have a lock setting. LG's recall label tells owners to use the Lock Out or Control Lock function when the range is not in use.
· Knobs on a back panel. Covers are sold for front-facing knobs. If your knobs sit on a panel behind the burners, read the cover maker's fit notes before you buy.
· Induction cooktop. Many have touch controls, so covers do not apply. Use the built-in Child Lock or Control Lock. If your induction range has knobs, the same fit checks as an electric range apply.

Measure your knobs and the gap between them before you order. One cover listing warns that minor marks may appear under a cover over time on delicate finishes.

How much do stove knob covers cost?

Not much. Three U.S. store listings we checked in October 2026 priced a 5-pack of clear flip-top covers at $7.75, $11.99 and $13.99. Taking the knobs off costs nothing. A built-in control lock is free if your stove has one. Two recent range recalls sent owners free covers or locks.

The three prices were all for the same kind of 5-pack, on the Indiana University Safety Store, Mega Babies and Hemlock Hardware. Prices change often. The free covers and locks came with the Samsung and Insignia recalls, for those models only.

Do stove knob covers work for adults with dementia?

They can help early on, but they are rarely enough on their own. The Alzheimer’s Association suggests knob covers, removing the knobs or turning off the gas when the stove is not in use. It also suggests appliances that shut off by themselves. Most covers are built so any adult can open them, so a person who wants to cook may simply lift the lid.

Watch how the person reacts. The Alzheimer's Association lists changes in surroundings, and the frustration of trying to make sense of a confusing world, among the common triggers of agitation. A knob that suddenly will not turn is that kind of change.

If covers cause upset, or the person gets around them, try a quieter option. A shut-off device sits behind the stove and cuts power or gas on its own. Talk with their doctor or care team about the kitchen as a whole. Our guide to stove safety for elderly parents walks through which device fits each stage.

What are the limits of stove knob covers?

· Heat. They are plastic. One maker says to remove its covers before using the broiler, to prevent damage from heat.
· Fit. They are made for front-facing knobs of a certain size. Closely spaced or odd knobs may not take them.
· Children learn. The same maker calls its covers only a deterrent, not a substitute for adult supervision. It says to stop using them once a child is old enough to defeat them.
· Adults can open them. They are built for easy adult access. That is the point for a parent, and the problem for someone with dementia.
· They do nothing once a burner is on. A cover cannot help with a pot someone started and forgot. NFPA says unattended cooking is the leading cause of kitchen fires.

One more point. CPSC's own childproofing guide lists anti-tip brackets for ranges, plus smoke and carbon monoxide alarms. It does not list stove knob covers. They are a useful extra, not a core safety device.

What else keeps young children safe at the stove?

· Keep a "kid-free zone" of at least 3 feet around the stove and wherever hot food or drinks are made or carried (NFPA).
· Check that the range is held by an anti-tip bracket. CPSC says many range tipover deaths involved children younger than 10 (CPSC).
· Turn pot handles inward while cooking.
· Move cookie jars and other tempting items away from the range, so the oven door is not used as a step.
· Check that every knob is off before you leave home or go to bed.

The last three come from CPSC's tipover alert and its advice to owners of the recalled ranges. None of them replaces an adult in the kitchen.

Why do range recalls include knob covers?

Because knobs on the front of a range are easy to bump. Three recent CPSC recalls deal with this:

· Samsung, August 2024. About 1,120,905 slide-in electric ranges. Over 300 reports of knobs turned on by people or pets, about 250 fires and about 40 injuries. The fix was a free set of knob locks or covers.
· LG, February 2025. About 500,000 electric ranges. At least 86 reports and more than 28 fires. The fix was a free warning label that tells owners to use the range's lock function.
· Insignia gas ranges, July 2026. About 3,820 ranges in the U.S. One report of knobs turned on by accidental contact. The fix was a free set of compatible knob covers.

If you own a range with front knobs, look up your model on CPSC's recall site. The remedies in these three recalls were free.

When is a monitor or a shut-off device the better step?

A cover solves one problem: a knob turned on by someone who should not turn it. It does not help when the cook turns a burner on and forgets it. For that, look at a device that watches the stove.

· A shut-off device cuts power or gas when cooking is left alone. It fits a cook who may not respond to an alarm, such as a person with moderate dementia. Our guide to automatic stove shut off devices compares types and prices.
· A monitor watches the burners and alerts someone. It fits a cook who still cooks well but sometimes forgets, when someone can act on the alert.

Many homes use a cover and one of these together. For a gas stove, also learn what to do if you smell gas.

Where Stovyn fits

We make Stovyn, a stove monitor. It does not lock knobs and does not shut the stove off. A thermal sensor above the cooktop reads each burner. If one is left on, Stovyn beeps at the stove, then alerts your phone, then texts the family or friends you chose if nobody responds. It works on gas, electric and induction. A cover stops the knob. Stovyn tells you about the burner that got turned on anyway. Stovyn Standard is $99 and Pro is $199. It is a pre-order and ships December 20, 2026.

Frequently asked questions

Do gas stove knob covers stop gas leaks?

No. A cover only makes a knob harder to turn. It does not seal anything. If you smell gas, leave the home and call 911 or your gas utility from outside. Our guide to a gas smell near the stove has the full steps.

Can I cook with the covers on?

Yes, that is how most are used. You lift the lid, turn the knob and close the lid. Check the maker’s instructions for heat limits. One maker says to take its covers off before using the broiler, to prevent heat damage.

At what age can a child open stove knob covers?

There is no set age. One maker says its covers are only a deterrent, not a substitute for adult supervision, and to stop using them when a child is old enough to defeat them. Keep a kid-free zone of at least 3 feet around the stove, as NFPA advises.

What are gas stove safety knobs?

The phrase is used two ways. Some gas cooktops have knobs you must push in before they turn. Others mean covers or locks added on top of the knobs. Check your manual to see which kind your stove has.

How do I know if my stove has a built-in knob or control lock?

Look in the manual or on the control panel for a setting called Lock, Lock Out, Control Lock or Child Lock. On the cooktops we checked, you press and hold a lock key. LG told owners of recalled ranges to use the Lock Out or Control Lock function when the range is not in use.

Does Stovyn stop someone from turning on the stove?

No. Stovyn is a monitor. It does not lock knobs and it does not shut the stove off. A thermal sensor reads each burner. If one is left on, Stovyn beeps at the stove, then alerts your phone, then texts the people you chose if nobody responds.
