Almost 500,000 Kidde smoke alarms sold in the U.S. are potentially being recalled because they may not alert people to a fire, according to the U.S. Consumer Product Safety Commission. The recall applies to Kidde dual-sensor (photoelectric and ionization) smoke alarms, models PI2010 and PI9010.

The alarms were sold at Menards, Home Depot, Walmart and online at Amazon.com, ShopKidde.com and other websites from September 2016 through January 2018. According to the Kidde website: "A yellow protective cap in limited instances may have been left on one of the two smoke sensors in affected products during the manufacturing process, which could compromise the smoke alarms’ ability to detect smoke."

Kidde can be reached toll-free at 833-551-7739 from 8:30 a.m. to 5 p.m. Monday through Friday, from 9 a.m. to 3 p.m. on Saturday and Sunday, or online at www.kidde.com.
