Kidde carbon monoxide alarm chirping every 30 seconds after about seven years: meaning and exact next steps

chirping every 30 seconds after about seven years means End-of-life warning. Kidde says that seven years after initial power-up a Kidde CO alarm begins chirping every 30 seconds, and the chirp does not stop until the unit is powered off. Kidde warns the alarm will not respond to carbon monoxide in this condition.

Kidde carbon monoxide alarm code error-condition-chirp-every-30-seconds

Error condition. Kidde says the alarm chirps every 30 seconds to indicate a very low battery or a unit malfunction.

Replace the battery with the type the alarm specifies, if it takes a replaceable battery.

Kidde lists the very-low-battery cause first, so a fresh battery is the safe first step. If the chirp continues, the malfunction, end-of-life and error conditions share the same interval, so the age of the unit and Kidde's Product Support are the next step.

Kidde carbon monoxide alarm code low-battery-chirp-every-60-seconds

Low battery. Kidde says the alarm chirps once every 60 seconds to indicate the batteries need to be replaced.

Confirm it is a single chirp on a timer and not the loud repeating alarm.

Kidde's step is to replace the batteries and then test the alarm. If it keeps chirping after a fresh battery, the other conditions on this page apply, and Kidde says an end-of-life or sensor error will not respond to a battery change.

Kidde carbon monoxide alarm code malfunction-chirp-every-30-seconds

Malfunction condition. Kidde says the alarm chirping every 30 seconds could indicate a unit malfunction.

Note the interval and check the age of the alarm against its label.

Kidde's step is to call its Product Support when this occurs. Because the same 30-second chirp is also the end-of-life warning, the age on the label decides which of the two you are dealing with.
