when I came into shop this morning both carbon monoxide alarms were going off in camper. The camper is pluged in and gas is turned off. any ideas what could set off?
Strange it is a 2015 AF990 I have had about 1 yr the hard wired detector and the battery 1 I installed were both going off. nothing is turned on not even the heat in the shop. battery shows 13.1 volt. I had run a truck in the shop about 12 hr earlier and nothing happened.anything else set of carbon monoxide detector like sewer gas battery gas ect.
