both are lethal is concentration, but the CO2 is an expired gas from animals and has too reach MUCH higher levels...
and there isn't a readily available CO2 detector, unless you are gonna buy a used space shuttle.
first assume it is NOT a false alarm or faulty detector,
but you really should CHECK the device for reliability.
next what are the potential sources for co in the trailer air?
-the cook stove
-hydrocarbon burning space heaters
-the water heater
-the tow vehicle
-cigarettes (the primary cause of co levels in human blood)
-candles and oil burning lamps
-that campfire on the lounge floor?
and so on.
IF the only thing running OR burning fuel is the furnace, start there.
i m no hvac guy but with a 20+ year old central furnace...
-it should be CLEANED and free of obstructions (mice/nests/webs/paper n stuff)
-it is supposed to EXHAUST out of doors, so go open the outside cover and look
---AFTER turning it OFF and TURNING OFF the gas supply, and perhaps disconnecting the juice (12vdc and 120AC)
-look 4 the stuff blocking the exhaust and for gaps in the sealant or trim pieces
-now go INSIDE and remove the cover, again looking for stuff and gaps.
beyond THAT a qualified RV hvac tech needs to inspect it.
imo the MOST likely, major issue is failure in the heat exchanger/manifold thingy...
old ones CRACK and leak co, this is NOT a good thing.
any of the hydrocarbon burning STUFF can be an issue and each item needs 2b checked for venting, proper combustion and so on....
are u sure it's a CO detector and not a LPGAS detector?
does the detector take batteries or is it wired to the 12v
be safe, be sure, read the manuals and get a pro 2 check it out.
