CO2 detector/multi function

[Recently retired]

I currently have a 2022 Montana. The CO2 alarm thingy is in the outside wall of my kitchen table slide. This stupid thing keeps going off for no reason. We have had things checked and no leaks, however if my husband happens to be having an alcoholic drink and is sitting too close to it, it goes off. If I use hairspray too close to it, yes it goes off. Sometimes for no reason like in the middle of the night.
Anyone having issues with this thing? Very annoying having to open a window, put fan on and wait for it to go green again. Any suggestions? I just want to rip it out of the wall.

You need to replace it. With all the outgassing of the materials these rigs are made with, the sensors in the CO detector have been contaminated causing it to be way to sensitive to hairspray and hubbies farts. Notice I said CO and not CO2. CO2 is part of what you exhale when you breathe and is not what the sensor looks for. CO is the dangerous part of what is produced by burning propane and other fuels, so that's why you have that device inside your rig. Replace it with the exact same model so it will fit the same as the old one. The new one should last much longer than two years, but normally should be replaced about every five years or so. Do not use hairspray near the detector as that will definitely kill it fast.

If you mean the CO/Propane detector, we just replaced ours (5 year lifespan max) because it started beeping .

Thank you. I will order a new one. This one says 2026 but like you said it’s probably contaminated.
