Kidde smoke detector recall.

Kidde has recalled almost 500,000 dual-sensor smoke detectors in the U.S. and Canada because a manufacturing malfunction can compromise the devices' ability to detect smoke. Specifically, a yellow cap that was left on during manufacturing can cover one of the two smoke sensors, posing a risk of people not being alerted to a fire in their home.

Dual-sensor smoke detectors use photoelectric and ionization technology to detect both smoldering and fast-moving fires.

Both recalled models—the Kidde PI2010 and Kidde PI9010—performed very well in CR's tests. During our testing we did not encounter the problem for which the detectors were recalled.

"Given that recall response rates are typically low, we wanted to get the word out right away on this one," says Don Huber, Consumer Reports' director of product safety. "Smoke alarms can remain in homes for a long time, putting a lot of people at risk should there be a fire in their home. If you have either model of these Kidde smoke alarms in your home, check the date code of your smoke alarm and, if it is covered by the recall, follow the instructions in the remedy section of the recall notice."

Kidde is a well-known brand in fire prevention. In November 2017, Kidde recalled more than 40 million fire extinguishers because they can become clogged or fail to discharge during a fire. If you missed that recall, take a moment to read about the fire extinguisher recall now. Kidde is offering free replacements for anyone who owns the faulty fire extinguishers.

Details of the Kidde Smoke Detector Recall

The recall: This recall includes Kidde dual-sensor (photoelectric and ionization) smoke detectors (models PI2010 and PI9010). There were 452,000 sold in the U.S. and 40,000 in Canada.

The risk: A yellow cap left on during the manufacturing process can cover one of the two smoke sensors and compromise the detector’s ability to detect smoke, posing a risk of consumers not being alerted to a fire.

Incidents/injuries: The firm has received one report of the yellow protective cap being present on a smoke detector before it was installed. No reports of incidents or injuries as a result of a yellow cap being present have been reported.

Where and when sold: Menards, Home Depot, Walmart, and other department, home, and hardware stores nationwide, and online at,, and other websites from September 2016 through January 2018, for $20 to $40.

The remedy: The CPSC recall notice says consumers should remove a recalled detector from the wall/ceiling and visually inspect it through the opening on the side of the alarm for the presence of a yellow cap. Don't attempt to take apart the alarm, open the casing, or otherwise remove the yellow cap.

If a yellow cap is present, contact Kidde to receive instructions and request a free replacement smoke detector. Remove and discard the recalled smoke detector only after you receive and install a replacement detector. If no yellow cap is present, you can safely reinstall the smoke detector without taking further action.
