CO 2 gas alarms keeps beeping

[Mberwick]

I have a 2019 Jayco Eagle. The CO 2 alarm goes off almost every night between 9 and 10. It's hard wired. All asleep and nothing on. Any help to resolve wood be appreciated.

Does your dog sleep near the Co2 alarm? He may have gas.

(No, I am not kidding!)

No dog. It was beeping like 4 or 5 times now it's up to 20+ beeps.

Lots of things can set it off.

12v power being low will set it off. But this does not sound like the issue, but maybe worth checking your dc voltage.

Generally any bad odor, such as a dog's gas, shoe odor, trash can, will set it off. Anything near it? What is in the cabinet behind it? Leaking aerosol can?

They are also known to have a short life, so it could be having issues too.

We are full time. So not running on battery. Always plugged in. Nothing in cabinet but dishes.

The average life of these detectors is around 5 years. You may have gotten a bad one from the get go. Replacement is easy and available on Amazon. If you're still under warranty the dealer can replace it although I probably wouldn't drag my camper to the dealership, let it sit there for a month just for an $80 part.

What is the beep frequency? Usually a short beep every minute or so means low power, constant means a malfunction, and a true alarm is often 3 beeps, pause, repeat for a smoke warning, and 4 beeps, pause, and repeat for Co2 (I am not sure all brands do that). If it is the pattern of beeps then that could be caused by a quick change in temps or humidity. It shouldn't need replacement but possibly. ~CA

It beeps like 20+ times and then stops.

When it beeps, note the green and red lights. There's a description on the face of it describing what it's alarming to, power on, CO alarm, propane alarm, low battery, and end of life.

Do either of you use any aerosol product before it starts alarming? Mouth wash that contains alcohol? If it's the propane side alarming, there may be a minute leak that it's detecting, but you may not be able to smell. They can be very sensitive.

We had one that alarmed randomly, in a closed pop up in our driveway. No reason we could find, except for possibly the odors from the wood and canvas inside. We put a new one in, and it still did it.

Possibly a critter of some sort died in your underbelly/wall. Methane gas is a byproduct of decomposition and there could be your issue. Ask me how I know this. Full Time 11 years.

Had the same issue about a month ago. Read all the posts about how to clean it and make sure it is dust free, etc. etc. Tried it all...nothing.

Contacted the manufacturer as the unit was only 6 months old. They wanted serial # and pic of the current alarm. They sent replacement immediately. Very easy to undo 2 screws and it had wire clamps...undo and hook right back up...now we can sleep.

Manufacturer sent return label - boxed old one back up and sent it back to them.

All I was out was 10 minutes of my time.

Hope that helps.

Thanks I will look at it when it does it again.
