strange smell

the wife calls me today and says there is a strong smell of propane in the RV, she shut the tanks off, shut the furnace off. I've already winterized the unit, we were keeping it warm while we clean it out for the season. its been mild and i have a 100# pig hooked up. I get home and go into RV, there is a strong smell but it doesn't smell like propane to me, what else could this be? I don't want to turn on the propane again to check for leaks, but i might have to. anyone experience this? Does Propane leave a different lingering smell after it clears?

Could be an air admittance valve. I had one go bad under the island sink and it was a faint sewer smell.

went out and checked that, we have emptied tanks and have 1/2 gallon of pink in them. its almost like a faint burnt smell, i have a warranty visit to the dealer on the 5th of December, might let him chase it down.

I thought the air admittance valve was above the trap, I have not looked but it is below susceptible to sewer gas?

Jeff, the valve is physically higher than the trap but installed between the trap and tank. If it gets stuck you will know it. Mine smelled for a couple of days and stopped, replaced it as soon as I could...

Did the propane leak detector sound off? Might want to check the 12v. Trailer batteries.

When that valve goes bad it stinks. When mine went bad I first thought it was propane.

Sulfide from the batteries, check water level?
Refer ammonia leak?

It happened to me (batteries), except it set off the CO/Propane alarm

I checked the furnace exhaust and a critter had built a nest, some leaves and something, looks like a steel scouring material, it was jet black and wife confirmed, that was the smell when i took it to her. I fired up the furnace and now its sounds like its sputtering flame and it is smoking, white smoke coming out, shut it all down, i guess its time to clean it out, do you think this damaged anything?

try sucking out the exhaust with a shop vac. See if anything comes out.
