The other night after going to bed we heard this intermittent beep. Finally traced it to the CO Detector. The Error Code = Replace Unit. Found the instructions and it said after 7 years it would start to beep indicating it would need to be replaced. 7 years 2 month!
Anyone else have this happen?
CO Detector Replacement!
The nighthawk out in the shop did that early this year. I rotate them from the house to the shop. So I bought a new one for the basement next to the stoker, moved that one that is 3 years old upstairs and moved the 4 year old one from there out to the shop.
