carbon monoxide detector going off (update)

We have a 1 year old house and our basement carbon monoxide alarm (hard wired)went off. There was no possible source in the house so I suspected the CO detector. I plugged in a portable CO detector and it showed nothing. I replaced the bad CO detector and no more problems. They do fail. Replace your CO detector and if the new one alarms you really do have carbon monoxide entering your RV.

Every year, 28,000 to 35,000 individuals in the United States are sickened by unexpected carbon monoxide poisoning and roughly 500 individuals pass away, lots of in their own house. Carbon monoxide is colorless, odor free, and unappetizing. It can not be discovered by human beings without the assistance of a detector.
A brand-new research study, launched today in the Journal of the American Medical Association (JAMA), has actually discovered that carbon monoxide quickly goes through plaster wallboard (likewise called drywall), the product utilized to complete walls and ceilings in a lot of domestic houses. The permeable product not does anything to stop the gas from leaking through.
Here's where the issue becomes worse: Twenty-five states need that locals have a carbon monoxide alarm in their houses however in December 2012, 10 states excused houses that do not have an internal carbon monoxide-producing source, such as a gas oven or fireplace, or a connected garage where a vehicle might be left idling. This relocation stresses toxicologists who fear that these exemptions might offer individuals an incorrect complacency. It's thought that getting rid of the requirement for all the homes of have such alarms will result in an increased variety of unintentional carbon monoxide poisonings, especially in multi-unit structures.
In 2002, a North Carolina regulation in Oldenburg County needed carbon monoxide alarms in a lot of houses, however all-electric houses (multi-unit and single) without connected garages were exempt. There were likewise no constraints on the kinds of alarm utilized, a lot of utilized gadgets that run by electrical energy just.
According to a report by the Centers of Disease Control (CDC), there were 124 reported cases of symptomatic carbon monoxide poisoning over the following 9 days. Throughout power interruptions, individuals are more most likely to utilize carbon-monoxide-producing heating and cooking devices as well as generators that might be located close to vents, which can draw gas into the house.***Link Removed***

First thing I would do, is replace the battery, next, check the date on it, they have a replace by date on them.

And/or a vent fan is drawing heater exhaust back into the camper? Maybe a bathroom vent fan is on high or something? Our water heater is under the kitchen window, so when the heater is running we close the window to keep the exhaust outside.

Happens to us too. Is it windy?

Have u ever had the wh worked on or is your rv new to u?

Mine was a disaster that I ended up replacing. some idiot ripped it apart welded the tank and decided to slap it back together without seals. Major no no I constantly had the co2 monitor going off and smelling Burnt propane in the coach. Found out the seals on intake and exhaust were NOT THERE. They are pressed fit and mine was old enough the new one was a better choice.

You will have to yank it out to see if this is the problem which very much sounds like the case mine was an atwood model.

Get this fixed immediately or leave it off especially at night!

Check the outside screen, if it is plugged that could be the problem,

New battery in defector or new detector might be needed. They do get dirty/fail and need replacement after a few years. Good luck!

Turned it on again to check flame, got a blue flame and plenty of heat coming out. Any more thoughts?

Check that the water heater flue is clean and the flame looks good and the burner is adjusted properly. Incomplete combustion results in the production of much, much more carbon monoxide than proper combustion. My first guess would be insect nests or something similar in the burner or flue assembly. My guess may be completely wrong, of course; it would not be the first, and probably not the last time!

I would doubt that your detector is on the fritz since it correlates very closely to using a gas appliance. Figure out what's happening with the burner, and be thankful you had a working alarm to alert you to a potentially quite dangerous situation.

Good looking flam will be all blue. If more than the very tiniest flame tips are yellow, it means flame is starved for air and will be making carbon monoxide. Usually that is due to spider webs, wasp nests, or even dead stink bugs clogging things up.
