The CO Monitor in our Regency has been acting weird, or at least I hope it's the monitor. While at Anastasia Island a couple of weeks ago it alarmed and indicated 290 ppm of CO. From what I know of CO at that level we should have been exhibiting symptoms. I cleared it and it was okay for about two or three hours and it alarmed again at 288 ppm.
When we returned home I took it inside and put it on our kitchen counter for a couple of days and it never alarmed. When I put it back in our coach it alarmed after a few hours, again at 288 ppm.
Is the monitor defective or is there something that could be emitting CO in bursts? We did not have any appliances using propane other than the water heater which we turned off when we were not using it. What other gases could trigger the alarm?
I am very curious as to what it happening. Does anybody have any ideas?

Buy another CO2 detector and try it. We have a plug-in one in the house that registers readings...

I have 2 battery powered CO2 detectors in the Barth. One behind driver (near where our boys sleep on the front couch) and one in the very back (at the twin bed sofas where my wife and I sleep). I found out that (if we are parked) after running the gas Kohler generator for 1 hour or longer (it is mounted underneath the dinette which is next to the front sofa) the front CO2 detector would go off.

You can't be too cautious.

One of the guys on one of the bus boards found out that his was being set off by his batteries outgassing as they got older.

Not to nit-pick, but CO [Carbon Monoxide], and CO2 [Carbon Dioxide], are two different things. The threat from exhaust fumes is CO.

This link was posted years ago, but it's even better today. I interviewed the Doctor for a NASCAR article, which might still be here someplace, and he's a pretty extrordinary guy, in that he is so into what he does that he takes a mundane subject and makes it interesting.
