Check your smoke detectors – that’s the word of caution by the U.S. Consumer Product Safety Commission after a manufacturing glitch was found in a Kidde dual-sensor smoke alarm.

According to the recall, a yellow cap left on during assembly can cover one of the two smoke sensors, ultimately failing to alert consumers of a fire in their home.

The recall includes nearly 452,000 Kidde detectors, models PI2010 and PI9010, sold at The Home Depot, Walmart, Amazon, and several other home and hardware stores.

The company encourages consumers who purchased these detectors between September 2016 through January 2018 to remove the alarm and inspect it through the opening on the side to see if the yellow cap is present.
