The condensate dish inside the boiler can crack during a delayed ignition, allowing unburned gas to build up inside the sealed cabinet. If the gas ignites, the front cover can suddenly detach, posing a risk of serious injury or death from fire, carbon monoxide (CO) poisoning, and impact hazards.
A combi (or combination) boiler is a type of gas boiler that provides both a home's hot water and central heating. The hot water can exceed the temperature set on the control panel, posing a burn hazard to users.
The boiler door can fail to seal properly, due to incorrect burner door studs, allowing flames and gases to escape, posing fire and carbon monoxide (CO) poisoning hazards that can result in death or serious injury.

The boiler door can fail to seal properly due to incorrect screws, allowing carbon monoxide (CO) gases to escape, posing a carbon monoxide poisoning hazard.
The boilers can release carbon monoxide (CO) due to delayed ignitions or component damage, posing a risk of serious injury or death.

Crown Boiler
The blocked vent switch (BVS) can fail to shut down the burners if the boilers are installed at altitudes above 2,000 feet and the vent system becomes blocked. In such an event, the boiler can emit excessive amounts of carbon monoxide into the building, posing a carbon monoxide (CO) poisoning hazard to consumers.
The recalled residential boilers can be missing the flue inspection cover plate, posing a risk of exposure to combustion flue gasses and a carbon monoxide poisoning hazard.

The blocked vent temperature switch (BVTS) can malfunction, which can cause the release of gases, including carbon monoxide (CO), into consumers' homes, posing a risk of carbon monoxide poisoning.
Flue gas can escape from the gas boilers if the vent adapter is not securely reattached to the boiler after maintenance or repair, posing a carbon monoxide poisoning hazard to consumers.
The siphon can become blocked, leading to a delayed ignition that can damage the boiler's exhaust system, creating a carbon monoxide hazard.
The boiler heat exchanger back plate can corrode and leak flue gases, allowing the boiler to emit excessive amounts of carbon monoxide, posing a CO poisoning hazard to consumers.
Totals add up the figures the notices state, counting a reannounced or restated recall once; 34 of 37 notices add a unit count. A notice that gives no number adds nothing.
Counted across all 37 notices on file as of October 31, 2026. Each line says how many notices it rests on.
Amazon (1), Lowe's (1), and The Home Depot (1) are the stores named most often in the 34 notices that say where boilers were sold. 1 of the 34 notices mentions online sales.
The 32 notices that give a price range from $80 to $24,000. Half of them name a price of $3,300 or less.
By the 33 notices that give sale dates, half the products were on sale for 22 months or less; the longest for 11.5 years. Half the recalls came within 2 years of the first sale; the other half reached products that had been on sale longer.
A repair in 20 of the 21 notices that name a remedy, a replacement in 2. Some notices offer more than one.
Carbon monoxide is named in 26 of the 37 notices (70%), against 1% of all CPSC notices on file. Then poisoning (20), fire (11), explosion (3), and burn (2).
14 of the 34 notices that describe incidents report at least one. 20 said none had been reported when the recall was announced.
13 of the 37 notices list model numbers. They also name serial numbers in 20, date codes or manufacture dates in 14, UPC codes in 2. A matching model number is a reason to open the notice, not the last word.
Where the notices say the numbers are: “on separate labels on the outside of the left panel” (2 notices), “on a label on the bottom left side of the boiler”, and “on a silver label on the inside panel”.
United States (15), Canada (7), Germany (5), Belgium (2) and Japan (1), in the 33 notices that name a manufacturing country.
8 boiler notices in 2021–2025, the same as in 2016–2020. Across all CPSC notices on file, the count rose 16% over the same years.

Find the model number on the product's rating label, then type it into the model-number lookup on this page. A match means the number appears in an official CPSC notice; open that notice to confirm any date codes or serial ranges it lists. No match is not proof that a product is safe. 13 of the 37 notices here list model numbers. They also name serial numbers in 20 and date codes or manufacture dates in 14. The place they name most often is “on separate labels on the outside of the left panel”.
Follow the remedy in the official notice and contact the firm it names. Across boiler recalls, the remedies offered most often are repair (20) and replacement (2).
