Carbon Monoxide dectector going off
Have a new-ish truck camper and our CO alarm has been going off lately. It's closed up not in use, the propane is turned off and the alarm goes off every couple of days. I air it out and it stops but then starts back up after a few more days. We've had it since April and been camping with no issues, this just started recently. No it's not the low battery chirp, it beeps 4 times and says "alert carbon monoxide detected". What could possibly be causing a build up of CO when nothing is turned on and no on is in it? Do I just need a new detector, it's only 5 months old.
