Thank youRe: Chirping alarmsSo despite being only 2 yrs old it probably needs to be replaced :o(Re: Chirping alarmsNo I didn't. But one more comment is that it is is hard wired, not a battery ThanksRe: Chirping alarmsoh, our detector is a combo CO/LPRe: Chirping alarmsI just coincidently found this. Our detector has also been chirping. Our Entegra is a 2020 so the detector is only 2 years old.

It is just green. any suggestions on that? thanks ahead of time Michele
