lp fumes in camper

Ok let's get a few things straight:

- LP gas leak smells like rotten eggs. Will not set off a CO2 alarm
- Fridge leak smells like ammonia (because it is), also will not set off a CO2 alarm
- You can't smell CO2 - it's colorless and odorless

If the CO2 alarm is going off, you have combustion gasses (not LP gas) entering the camper. That's bad. I know you've cleaned your vent top and bottom. The fridge also as a chimney that runs up the back of it from where the flame peep hole is the whole way up. It could be clogged.

Sulfur smell will not set off a CO2 alarm. CO2 will set off a CO2 alarm (again, you can't smell what it's alarming on).

Since you typed CO2 so many times, I just have to point out, CO2 makes your soda fizz, CO is the carbon monoxide that can kill you. None of us have a CO2 alarm.

The likely cause of a carbon monoxide alarm is clogged air intake or exhaust on the burner. I'd say op was on the right track but something still needs cleaning.

Ha! That's funny. I saw CO2 and went with it. Of course it's CO (monoxide vs dioxide). Though I wonder if a CO2 alarm really exists (though not in the RV world).

OP
What model is your fridge???

To access/reach/clean flue out .....need to remove that roof vent again
Flue baffle (spiral plate that hangs down inside flue) pulls out and needs to be clean and flue cleaned

thankyyou for info on co2. there was mud dabber nest in where the flame lights. will try to see how that vent like tube can be taken out and cleaned. Will try after rain. thankyou

You may be smelling the coolant in the refrigerator. Pull off the back and see if there is evidence of a leak. I've been told that is a yellowish powder. The odor should be strong there.

thankyou. I have the burners on stove working and the WH going. So I have gas. Everything is turned off all gas things. Only have fumes when the refrig is on. Enough over night so alarm goes off. Like I said earlier, Vent up on top is clean underneath it. PS: did have sulfer smell when I run water thru camper. Put bleach and rinsed out.Refilled no problem with smell. thankyou for your response.

If you get a,rotten egg smell its quite possibly your out of gas.
