StoveTop FireStop Review: Rangehood 675-3D and the Recall

StoveTop FireStop Rangehood review: what the maker's manual warns, the 2019 CPSC recall, why it isn't UL-listed, and magnets vs stainless hoods.

By Maksud · Published Sep 26, 2026 · Updated Sep 27, 2026

The StoveTop FireStop Rangehood is a pair of powder canisters that hang by magnet under a range hood. Per the maker, they burst open when flames from a stovetop fire touch a fuse underneath. It’s a cheap extra layer for an electric stove. But it isn’t UL-listed, its own manual says it may not suppress all stovetop fires, and a 2016 batch was recalled by the CPSC.

It’s one of three devices in our kitchen safety devices guide. Mounting is covered step by step in how to install StoveTop FireStop. This page draws on the maker’s documents, the CPSC, a published review and local news; see how we research.

StoveTop FireStop Rangehood specs: $56.95 a pair, six-year life

The powder is potassium bicarbonate, per the Rangehood manual. That’s true of the 2017 edition and of the current one (675-3-117 Rev G, April 2025) linked from the product page. The maker’s current web FAQ calls it only a proprietary powder, blended to be gravity fed onto a cooking fire.

What the StoveTop FireStop manual warns

The Rangehood user manual (675-3-117 Rev B, dated February 2017) is more candid than the product page. It says the product:

• may not suppress all stovetop fires, and reignition is possible;
• is not recommended for gas stoves, because the powder may put out the burner flame (the 2025 Rev G manual drops this line and points to a gas-stove page saying the unit has been tested on gas and electric stoves but does not shut off the gas);
• is designed only for indoor residential stovetop grease fires using no more than 3/8 inch of oil before food is added;
• may briefly flare or splash grease when the powder hits the fire, which the manual calls normal;
• makes a loud pop when it activates, and should be discarded after activation or if dropped or damaged.

The manual also tells you to turn the burner off right after activation, if it’s safe to do so.

Is StoveTop FireStop UL listed? No, per the maker

StoveTop FireStop isn’t UL-listed, per its own FAQ, read on Sep 27, 2026. The FAQ answers “Is StoveTop FireStop UL Listed?” with no. The company says it doesn’t have UL certification yet, and that UL hasn’t found a standard to test it to. It says it conforms to “elements of UL 300A, 199, 711 and 1254,” but none of them completely.

That is the maker’s description of its own product, not a listing by UL. I couldn’t check UL’s Product iQ database, which requires a sign-in. I found no other certification.

Does StoveTop FireStop work? Demos, not lab tests

No lab I could find has published measured activation times, powder coverage or knock-down results. What exists:

• Reviewed.com tried one in its parking lot under the eye of a former fire chief, without setting a real fire. It noted the pop is slightly louder than a firecracker and each pod holds a surprising amount of powder. It listed single use and the chance of putting out a gas burner flame as cons (Reviewed, updated May 2022).
• Maple Grove Fire Department (Minnesota) ran an on-camera demonstration, reported by local community station CCX Media on April 15, 2024. An investigator heated a small pot of oil on a propane burner until it ignited. When the flames reached the canister mounted above, it released its powder, and the report says the fire went out. It was a single demonstration set up to show the product, not a measured or repeated test.
• Oshkosh Fire Department (Wisconsin) gave canisters free to food-pantry visitors aged 60 and older, WTAQ reported on April 2, 2024. The department’s spokesman also told residents to keep working smoke alarms. He said to call the fire department after any activation.

Those are real signs of confidence from fire services. But they aren’t the same as a certification or a published test.

The 2019 StoveTop FireStop recall: date code 4516

On December 6, 2019, WilliamsRDM recalled about 9,300 pairs of StoveTop FireStop Rangehood (675-3D) and Microhood (677-2) suppressors, CPSC recall 20-037. Per the CPSC notice, the suppressors can fail to activate. The company knew of two that failed during product demonstrations. No injuries were reported.

• Affected: units made November 7 to 13, 2016, sold in November 2016 through HD Supply, Interline, Louisville Fire and Safety, Central Wholesalers and HomeDepot.com for about $56 (Rangehood).
• How to check a Rangehood: silver metal with a red label and date code 4516 stamped under the magnet assembly, per the CPSC.
• Remedy: free replacement; the CPSC lists the company at 888-616-7976.

Those units are also well past the six-year life the maker gives, so they should be replaced regardless.

Will StoveTop FireStop stick to a stainless steel hood?

The canisters hold on with magnets, and many stainless range hoods aren’t magnetic. A fridge magnet tells you which case you’re in. If the magnets won’t stick but your hood is 27 to 35 inches above the stove, the maker’s FAQ says to order its alternative mounting kit. The kit page lists it at $2.75 (Sep 27, 2026) and says it fits the Rangehood and Plus models.

For microwaves or cabinets 15 to 27 inches above the cooktop, the maker’s 2017 FAQ points to a different model, the Microhood. The installation guide walks through both mounting methods.

StoveTop FireStop owner reviews: none we could read

I couldn’t load Amazon’s or Home Depot’s review pages, and found no forum threads. So I can’t describe a pattern of owner complaints. The known issues are the recall and the stainless-hood magnet problem, both documented above by the CPSC and the maker.

It doesn’t replace the basics

Unattended cooking was the leading factor in U.S. home cooking fires and casualties from 2017 to 2021, per NFPA (NFPA, Home Cooking Fires, 2023). The U.S. Fire Administration’s advice is to stand by your pan and turn the burner off if you leave the kitchen (USFA).

NFPA’s tip sheet says to smother a small pan fire with a lid and turn off the burner. If you have any doubt, get out and call 9-1-1 from outside. A canister is an extra layer on top of that, not a substitute. The maker says it supplements a handheld extinguisher, and the Kidde FA110G is our pick for that.

Who the StoveTop FireStop suits (and who should skip it)

Consider it if your stove sits under a range hood 24 to 35 inches up (per the current manual). It suits someone who wants a device that can react to a pan fire when nobody is standing there. Accept going in that it isn’t UL-listed, and that the maker itself doesn’t promise it will put out every fire.

Think twice on a gas stove. The maker says it won’t shut off the gas and the powder may put out the burner flame, so you still have to turn the burner off. Skip it for deep frying beyond 3/8 inch of oil, or if you want a certified product. If the bigger risk in your home is forgetting the stove is on, the iGuard stove shut-off is designed to cut power before a fire starts.
