A missing cap on a kitchen range can let gas leak, and the ranges were recalled

Thousands of high-end dual fuel kitchen ranges are being recalled after the manufacturer discovered that some units left the factory without a cap on a gas test port, a gap that can let gas escape unnoticed inside a home. The recall, announced September 10, 2026, covers premium ranges built by AGA Rangemaster and its La Cornue brand and sold through authorized dealers for between $6,000 and $20,000. No fires, injuries or gas-related incidents have been reported, but the company is treating the fix as urgent enough to qualify for CPSC’s fast-track recall process, which moves a correction to market faster in exchange for the manufacturer accepting the hazard finding without a lengthy investigation.

The Recalled AGA and La Cornue Ranges

The recall covers freestanding AGA Elise and Mercury Series Dual Fuel Ranges, in 36- and 48-inch widths, and freestanding La Cornue CornuFé Series Dual Fuel Ranges, in 36- and 43-inch widths, built between March 19, 2025 and July 24, 2026. Affected models include the AEL361DF, AEL481DF, AMC36DF, AMC48DF, LAC9 and LAC1, sold in stainless steel, white and 13 additional colors, according to the Consumer Product Safety Commission. Every recalled range combines gas surface burners, configured for either natural gas or liquid propane, with one to three electric ovens depending on the model size. The serial number needed to check a specific unit against the recall is printed on a rating plate located on the bottom panel, underneath the storage drawer.

How a Missing Test-Port Cap Becomes a Hazard

Every gas range includes a test port used by technicians to check gas pressure and line integrity during installation or service; once that check is complete, the port is supposed to be sealed with a cap so the connection cannot leak during normal use. On the recalled units, that cap can be missing, leaving an opening in the gas line that allows gas to escape slowly into the surrounding air rather than being fully contained within the appliance. Because the leak originates inside a sealed test port rather than at a burner or connector a homeowner would normally inspect, it is not the kind of defect a consumer could reasonably catch through routine use, which is part of why CPSC classified the risk as fire or explosion rather than a lesser hazard category.

Why This Recall Moved Through CPSC’s Fast Track

This recall qualified for CPSC’s Fast Track Recall Program, an option available to manufacturers willing to act quickly once they identify a defect. Under the program, a company reports the hazard to CPSC as required under the Consumer Product Safety Act, then works directly with the agency’s compliance staff to launch a voluntary recall within about 20 working days, without CPSC first conducting its own extensive technical investigation or issuing a preliminary hazard determination. In exchange for that speed, the manufacturer effectively accepts the hazard finding rather than contesting it, and the recall reaches the market faster than a standard investigation-first process would allow. AGA Rangemaster’s use of that path tracks with the company’s own messaging that consumers should shut off gas to an affected range immediately rather than wait for a scheduled repair, treating the missing cap as urgent even though no fires or injuries have been reported.

A slow leak from an unsealed test port is particularly hard for a homeowner to notice because natural gas and propane are odorless in their raw form; utilities and manufacturers add a sulfur-smelling compound specifically so a leak has a detectable warning sign, but a small, steady seep behind or beneath a range can disperse before it reaches a concentration a person would recognize by smell, especially in a well-ventilated kitchen. Left unaddressed, an accumulating leak raises the risk of ignition from something as ordinary as a pilot light, a spark from an electrical switch, or the range’s own igniter, which is why CPSC’s hazard description centers on fire and explosion rather than a slower-developing risk like carbon monoxide exposure.

Scope of the Recall and Where the Ranges Were Sold

Roughly 3,992 of the recalled ranges were sold in the United States, with an additional 336 sold in Canada. The ranges were distributed through authorized appliance dealers nationwide from March 2025 through July 2026. Given the price point, the recalled units are concentrated among higher-end kitchen renovations rather than mass-market retail, which narrows the affected population but also means many owners may not check a government recall list the way they would for a common household appliance bought at a big-box store.

The scope also extends beyond the United States: Canadian regulators issued a companion recall covering roughly 336 of the same ranges sold north of the border, describing the identical missing test-port cap and instructing Canadian owners to take the same immediate gas-shutoff step, according to the Canadian recall notice. A dual-market recall like this one is typical for premium European-designed appliances, which are often imported and distributed through the same authorized-dealer networks in both countries rather than being manufactured separately for each market.

The Gas Shutoff and Repair Process

AGA Rangemaster is telling consumers to shut off the gas supply to their range immediately and determine whether their unit is subject to the recall by checking the model and serial number against a dedicated recall webpage set up for the AGA and La Cornue brands. Units confirmed to be affected qualify for a free inspection and repair by a certified technician. In the meantime, the company says the electric oven sections of an affected range can continue to be used safely, but the gas surface burners cannot be operated until the repair is complete. Owners with questions can also reach the AGA Rangemaster recall line by phone, staffed on weekdays.
